gas oven safety valve leaking supplier

I picked up a second-hand Kenmore 790.70613210 and found out the oven did not work. After replacing the igniter (which didn"t fix the problem), I got this valve. While I do not know if the valve in the oven had ever been replaced before, this was the same valve as the one that I took out, and it fixed the problem. Box the valve came in said Robert Shaw which is a good brand. Time will tell if it holds up, but so far so good.

Igniter was glowing red and current flowing through it to the gas valve read just shy of 3 amps. Troubleshooting videos will generally lead you towards the igniter if the current flowing to this valve is less than ~3.2 Amps, so I replaced the igniter. No change in current and still no working oven. I installed this new valve, and current came up to spec and everything worked as it should. I am using propane, so I had to adjust the orifice a bit to get proper combustion, but otherwise this was a quick and painless process.

Thank you for your inquiry. The oven safety valve is one part that may fix the issue, but there are some other parts that you will need to check to see which one is causing the issue. You will need to check the igniter, the electronic control board and the temperature sensor. I hope this helps. Thank you and have a great day!

Can this oven valve work on my range? The range was plugged into the wrong outlet and it shorted out, the igniter glows when the stove is turned on however the burner isn"t lighting. I was told the the valve needs to be replaced.

Thank you for your question. This is not the correct safety valve for your appliance. I have listed the correct valve below for you. I hope that helps. Good luck with your repair.

Oven doesn"t heat. Igniter glows when gas is turned on, voltage on value starts near zero and slowly ramps up to just under 3 volts, but gas never ignites. The slow ramp seems normal to allow igniter to get hot, but not sure what the valve"s voltage should be to have it open. Valve coil is not open per ohm meter. Sounds like a bad valve? Thanks.

Hello Curt, Thank you for your inquiry. It sounds like it could be either this part or the pressure regulator. When the ignitor heats up to a certain temperature, it is supposed to trigger the valve to open and let the gas in to ignite and the regulator cuts it off at a certain pressure. Hope this helps!

Hello Sal, thank you for your question. You can test the gas valve to see if it has gone bad. You will need to test this with a multimeter. Here is a video that will show you how to test that valve.

Hello Steve, thank you for your question. The oven safety valve part number WB19K31 will work with either NAT or LP gas. The part itself can be switched over without any additional parts. Please check your owners manual on steps to change that over. I hope this helps!

In the oven a wire from the igniter shorted (had to pry the wire off the wall) to the frame. Would the control valve or the thermostat also be damaged. Where is the thermostat located on the stove. I noticed that the plastic on one of the knife connection on the control valve was missing

Hello Robert, thank you for writing. It is doubtful that the Oven Safety Valve or Oven Thermostat were also damaged when this occurred. The Oven Thermostat (part PS235170 on your model) is located behind the Manifold Panel (control panel). We hope this helps.

Hi there, i have a GE gas range (model jgbp28sem1ss) and need to replace the safety valve for the part of the oven that bakes. Is this the correct part? Thanks

Using a Phillips screwdriver, unthread the screw securing the burner tube to the oven. Take the tube off the gas orifice and carefully set it down on the floor of the oven.

Move to the back of the oven and take out the screws holding the lower, rear access panel to the appliance. Once the panel is off, disconnect the wires from the gas safety valve, and use a 9/16 inch wrench to loosen the nut securing the gas line to the valve. Then, unthread the mounting screws holding the safety valve to the back of the range. Lift the gas safety valve up and off the oven.

To install the new safety valve, insert the orifice tube into the hole in the back of your oven. Align the valve with the gas line and reattach the two mounting screws that secure the safety valve to your appliance. Next, reconnect the wires and tighten the gas line nut with a 9/16 inch wrench. Put the lower, rear access panel back on, and reattach the screws you removed earlier.

Move to the front of your appliance and reinstall the burner tube to the safety valve’s gas orifice. Once the connection is secure, reattach the mounting screw that holds the tube in place. Next, replace the lower access panel in the oven cavity and put the racks back in your appliance.

Plug your appliance back in, and turn on the gas supply. If you smell gas at any time, shut off the gas supply and inspect the safety valve connection.

The range is leaking propane gas. I replaced the supply line and tested the new connections with soapy water and the were fine. I also tested the valve and other connections between the valve and the kitchen wall. The new supply line seemed to have done the trick. But, the next day after successfully using both the oven and the burners, the kitchen smelled like propane again. Sniffing about, it appears to be coming from the oven. Someone told me to check to see if all the holes in the oven burner were producing a flame and they are. So, I"m wondering if there is a likely culprit here or if I have to trace the gas path to find the leak. If the latter is the case, then where the best place to start. Also, I recently replaced the glow bar igniter to fix an erratic oven temperature and slow heating issue. Does anyone have any suggestions?

Most modern appliances have safety features built in, but your gas oven safety valve is arguably the most important. If an electrical appliance malfunctions, it can cause a fire, but a misfiring gas oven could potentially blow up your house. You don"t ​really​ need to know how the safety mechanism works to use your oven, but you may find that it gives you some extra peace of mind.

Broadly speaking, there are two ways a built-in safety mechanism can work. One option is that it remains "open" by default and to shut off if certain conditions are met. That"s how fuses and circuit breakers work in an electrical circuit: Ordinarily, the electricity is free to flow, but if the current grows too large, the fuse or breaker will blow and cut off the circulation of electricity.

The other option is for your safety mechanism to be "closed" by default and allow a device to operate only when the correct conditions are met. That"s how a gas oven safety valve works. Gas ordinarily is prevented from flowing, and if the valve is working correctly, it opens only when you want to light your oven.

Many gas stoves use what"s called a "hot surface igniter," a bar or element (similar to the ones on your stovetop) that gets hot enough to ignite the gas on contact. Gas oven safety valves on stoves with this type of ignition system take a couple of different approaches.

In one approach, a bimetallic strip operates the valve. It harnesses a simple scientific principle: Metals expand and contract at different rates when they"re heated and cooled. If you bond two suitable metals together in one strip, that strip will flex to a predictable degree as the temperature goes up and down. Wall-mount thermostats often use this principle, as do analog oven thermometers and the thermometer in the lid of your gas grill.

As appliance-repair website PartSelect explains, turning on your gas oven causes electricity to flow into the heating element of your hot surface igniter. As the igniter heats up, it warms a bimetallic strip inside your gas oven safety valve. When the igniter reaches its operating temperature, the bimetallic strip opens the valve and allows the gas to flow, igniting as it crosses the heated surface.

According to heating-equipment vendor Anglo Nordic, gas oven safety valves use a variation of that principle to operate. In these stoves, the flow of electrical current through the hot surface igniter becomes the control mechanism. The igniter"s bar is made of a material that offers less and less resistance to electricity as it heats. When it reaches the temperature required to ignite the gas, its resistance becomes low enough to trip the safety valve and open the flow of gas.

More modern ranges use an electrical igniter. When you turn on your oven, the gas begins flowing immediately, and it sends an electrical current to a piezo electric igniter. The current makes the igniter spark (like the manual igniter on your gas grill) and lights the oven"s burner. In this case, the safety valve works in the opposite way: An electronic sensor checks for the heat caused by ignition after a few seconds, and if it"s absent, it will close the valve and shut off the flow of gas.

It"s worth pointing out that not all gas ovens have a safety valve in the conventional sense. Older stoves simply use a pilot light, a small but constant flow of gas, which, in turn, feeds a small, candle-like flame. You essentially ​are​ the safety mechanism in this system: It"s up to you to check that the pilot is lit. When you turn on the gas manually, the small pilot flame ignites the main flame. It"s a mechanically simple system, which makes it durable, and for that reason, you"ll still see it used on commercial restaurant ranges, which must stand up to decades of heavy use.

Gas ovens contain a number of valves depending on their age and design: pilot safety valves, oven safety valves and thermostatically controlled valves. Any of these valves contain gaskets that may leak with age as well as develop leaks where they connect to the oven’s system of gas pipes or tubing. Older ovens that use the oven’s control knob to control gas flow are prone to develop leaks because of the constant use this control receives.

A slow gas leak may not produce enough scent to be detectable, and even large leaks may not be detected by people with a weak sense of smell. A gas leak detector can give you peace of mind and help keep you and your neighbors safe by sounding an alarm before natural gas reaches the explosive range.

Gas leak detectors are available at many hardware and home improvement stores, as well as online. These combustible gas detectors come battery operated or require power from an electrical outlet. The best installation is within 12 inches of the ceiling in the same room with the natural gas pipe or appliance, such as a stove or gas-powered fireplace. For your protection, it’s important to follow your device’s installation instructions carefully.

Good to know: A carbon monoxide detector is not the same as a gas leak detector. While there are combination devices on the market, most carbon monoxide detectors do not detect combustible gasses. Be sure to check the label.

Pressure cookers have become commonplace in modern households, and their improved safety features have made them twice as popular. In the past, pressure cookers earned a dark reputation for explosions, but today, most pressure cookers have a minimum of 10 or more safety features.

That said, when the pressure cooker safety pressure valve starts leaking, you should know the cause because pressure cookers must release steam to stay safe.

You find many pressure cooker safety valves on top of the lid near the handle, but this depends on the type. If you see a leak from here while pressure cooking, that doesn’t always mean danger.

The safety valve releases the steam to lower the pressure to safer levels and regulate the pressure. The newer models, like the electric pressure cooker, even release the steam using a computer chip. A pressure cooker model like this will release light vapors or condensation from the safety valve, which doesn’t pose a danger.

Important to note: The safety valve leaking doesn’t pose a danger as long as the pressure cooker continues to build to the desired PSI. Once you reach your desired PSI, the safety valve should stop leaking altogether. If it continues to leak, that indicates pressure control failure.

Pressure cookers will open the safety valves enough to release the pressure cooker steam building in the pot. This causes a hissing sound or rattling sound. Don’t feel intimidated that is normal. If you wanted a quieter pressure cooker, electric pressure cookers don’t make as much noise.

You must maintain consistent pressure to ensure that the pressure cooker will cook the food all the way through. Safety valves can be bought and replaced if you have a broken one. However, buy a quality safety valve from any of the reputable brands to ensure the quality.

Manufacturers made safety valves to protect consumers from exploding pressure cookers. If you have a defective safety valve that doesn’t leak, you could use it. You could use it, but you wouldn’t be wise to do it. Don’t do this.

Safety valves let out the dangerous excessive steam. When they leak, they let out steam unnecessarily, and the pressure cooker won’t cook the food. On the other hand, when defective and closed, you have a higher risk of it exploding. Never use a pressure cooker that has either a leaking valve or a defective valve.

You don’t want to see steam exiting the safety valve because the leaking from high pressure can put you in a dangerous situation. The escaping steam can cause second and third-degree burns if exposed to the skin. If you notice a leak, immediately turn off your pressure cooker from the heat source and release the steam. Even smaller leaks pose a danger.

Steam exits from the safety valve of your pressure cooker because of a broken disc, or rubber gasket, on the inside. Because of this, it releases too much steam and the vessel never boils. If you have damage to the valve, you will see a hole in the valve.

Warning: Working on the safety valve yourself does pose a small level of danger. Do this at your own risk. If you don’t want the risk, then take it to an authorized service center. A utensil repair professional can also repair this, but it depends on how much damage was done to the pressure cooker.

As we said, you can use two methods to replace the safety valve if you have a leak: You can replace it from the inside of the lid, or you can replace it from the outside of the lid. Before attempting either consult your user manual.

To replace the safety valve from the outside, you will use a screwdriver on the outside to turn the screw, while you hold the screw and keep it from twisting on the inside. Once it releases, use a cotton swab to clean the inside of the hole.

Check for surface damage as well to make sure that you don’t have structural problems. Examine the o-ring as well to make sure that it doesn’t have defects. Replace the safety valve with the new one and tighten it up.

From the inside, you will use a wrench to unscrew the safety, while the screwdriver will hold the screw in place. Once you have released it, do the same thing as you did with the first method. Replace the safety valve and tighten it back up.

While you can replace them via the DIY method, don’t try to fix a broken safety valve. The replacement parts only cost between $2 to $17 to replace a safety valve. Buy from a genuine brand because it guarantees that you fix the problem.

Considering the cheap cost, you may want to buy a spare because you can replace it at a moment’s notice. When the pressure reaches a dangerous level, the safety valve acts as the canary in the coal mine. This blows out before it explodes. The safety valve attempts to bring the pressure back down to a normal level.

Never use a damaged valve because it doesn’t provide the same level of protection. You may experience similar problems as before like the valve leaking, or the valve shutting down altogether. Both scenarios put you in a dangerous situation.

The safety valve leaking poses a danger at the first sign of damage. With that in mind, a leak only gives you one example of what can happen to them. You should replace the safety valve whenever it becomes cracked or brittle. As soon as you see the damage, replace it.

Inspect the safety valve for signs of wear before each use. Another reason that manufacturers say to only fill the pressure cooker two-thirds full is that it ensures that the food doesn’t block the safety valve. The pressure cooker will build a dangerous level of pressure if that happens.

Let’s say that the food blocked the pressure release valve. The safety valve may melt to release the steam. That becomes the last stop before the pressure cooker explodes. The valve helps to maintain the pressure levels. While you have other safety features, this component especially protects you.

Thorough cleaning after using your pressure cooker will go a long way to helping it stay in tip-top condition. Handwash the pressure cooker lid with soap and warm water. Never put a pressure cooker in the dishwasher because this can be hard on the more sensitive components like the gaskets and rubber ring or seal.

A leaking safety valve doesn’t always mean danger, but look for the cause if it continues after you reach the desired PSI. Some steam leaking is normal, but you shouldn’t see an excessive amount of it leaking. That indicates that your pressure cooker has too much pressure.

Never try to repair a damaged safety valve. You can simply replace them, but if you don’t feel comfortable doing it yourself, hire a professional. Always pay attention to leaks because they can stop your pressure cooker from building pressure.

WITT is a manufacturer of Pressure relief valvesor Safety relief valves for technical gases. They are designed to protect against overpressure by discharging pressurized gases and vapors from pipelines, pressure vessels and plant components. Safety relief valves (SRV) are often the last line of defense against explosion – and such an explosion could be fatal. Other common names for safety relief valves are pressure relief valve (PRV), safety valve, pressure safety valve, overpressure valve, relief valve or blow-off valve.

WITT safety valves are very precise. They are individually preset to open at a predetermined pressure within the range 0.07 to 652 Psi. Their small size and orientation-independent installation allow a wide range of connection options. WITT relief valves also stand out due to their high blow-off flow rates of up to 970m³/h. They can be used within a temperature range of -76° F to +518°F and even with very low pressures.

For maximum safety, WITT undertakes 100 % testing of each safety relief valve before it is delivered. In addition, WITT offers individual testing of eachsafety valveby the TÜV, with their certificate as proof of the correct set pressure.

WITTsafety relief valvesare direct-acting, spring-loaded valves. When the preset opening pressure is reached, a spring-loaded element in the valve gives way and opens, and the pressure is relieved. Once the pressures are equalized, the valve closes automatically and can be reactivated any time the pressure rises again. Depending on the application and the nature of the gas, the safety relief valvescan either discharge to atmosphere, or via a connected blow-off line. The opening pressure of the safety valves is preset by WITT at the factory according to the customer’s requirements.

Safety relief valvesare used in numerous industries and industrial applications where, for example, gases pass through pipelines or where special process vessels have to be filled with gas at a certain pressure.

For most industrial applications using technical gases, brass is usually the standard material of construction of thesafety relief valvebody/housing. For the use of pressure relief valves with aggressive and corrosive gases, the housings are made of high-quality stainless steel (1.4541/AISI 321, 1.4404/AISI 316L, 1.4305/AISI 303 or 1.4571/AISI 316Ti). The use of aluminium as a housing material is also possible.

Depending on the type of gas used and individual customer requirements, various sealing materials and elastomers are available to ensure the safety of your systems under even the most difficult conditions.

WITT pressure relief valves are available with different connections. In addition to the standard versions with the usual internal or external threads, special versions with KF or CF flanges, VCR or UNF threads can also be ordered. Special adapters for connecting the safety relief valve to a blow-off line are also available.
