The time has come and the epic barbecue dinner you had planned is in play as friends and family arrive. It’s time to fire up your barbecue grill and preheat it so you can begin cooking. Then you notice the flame is low, and that the grill is only heating up to 250 or 300 degrees Fahrenheit – or maybe it’s not even igniting!!! Don’t panic! There’s no need yet to call your local grill store to come out and fix it yet. This post may just save the day and some of your hard-earned money! …

* Side note about the shut down procedure. The following ignition sequences are written assuming you are turning the burners off 1st, then the Propane Tank. Therefore, each sequence starts from the “all off” positions. You can turn the burners off and leave the Propane Tank on; however, we strongly recommend you to go ahead and turn the Tank off also.

To put it simply, the key is to be sure you have your burners off before you turn on the Propane. If you turn the burners on first the gas will not be pressurized in the gas line causing the Bypass to trigger. You see, in this case the system detects there is a gas leak; hence, the bypass triggers.

* When using the improper sequence, the regulator will trip because by turning the burners on 1st, you empty the lines of any propane which causes the low line pressure.

If after having deployed this fix the issue persists, it’s time to call your local BBQ Grill Repair Company. There are numerous other more advanced issues that can occur. For instance, you may have a blockage in the Venturis Tubes. A blockage like this is caused by char/grease build-up. You can decrease the likely hood of this ever happening by being sure to have a BBQ Grill Cleaning done regularly.

An OPD Cylinder Valve is indeed a part of your propane tanks’ inherent safety design. However, it does not have a “Bypass” as your regulator does, nor is it designed as a safety mechanism during usage. This device is required on all 4 to 40 pound DOT cylinders.

OPD stands for Overfilling Prevention Device and its first function is to do just that, prevent the user from overfilling the device. In addition, the device disallows Propane from flowing out of the cylinder if the triangular handwheel is opened and there is no gas line connected. It does this because there is no connected regulator to push open the valve’s orifice. Moreover, Propane OPD valves operate inside the bottle and are activated as the cylinders liquid propane rises in level pushing the float upward, therefore, stopping the flow of gas into the tank. This action is similar to that of a toilets float valve; once the water in the bowl rises to a certain level, the flow of water stops.

The OPD Valve is one of the main focuses regarding the fact that tanks are to be recertified 12 years after original manufacturer dates and every 5 years thereafter. Inside, there are what you can call “O-Rings” that need to be changed out at those predefined intervals. Also, the mechanism itself can be swapped out for a new one. Tampering with this device is NOT RECOMMENDED. If you suspect there’s an issue call your local propane delivery supplier and they will deal with it properly.

bottle feels heavier and obviously is filled with propane but opening the valve produces no escaping gas. OPD valves are designed so that propane will not flow from the service valve unless it is hooked up to a hose end connection.

Do you want to know how to reset the gas grill regulator? It can be because you turned the grill on to warm it up, hoping that the grill will be ready to cook by the time everyone arrives. Then you realized that the flame is weak, and the grill temperature only goes up to 250 or 300 degrees Fahrenheit. Started to panic? Read this to know the proper way to rest the gas grill regulator before calling your BBQ Grill Repair Company.

Why here? You’re right to think about why we have added a summary at the beginning of the article. The reason is, a glance will help you know that you’re at the right place to learn about regretting the propane regulators.

A gas grill regulator is a small device that is screwed onto an LPG or propane tank. It regulates the gas flow from the gas tank. It also includes a safety mechanism known as a bypass. The gas regulator consists of a ball and spring and automatically cuts off the gas supply when the hose is devoid of the back pressure.

Generally, it happens when there’s a leak. It can also be activated if the gas tank and one of the burners are turned on. You should turn off the gas tank and wait for a while before turning on the burners.

The grill regulators (or propane gas regulators) are a component of the gas grills that controls the gas flow from the fuel canister to the heating element. It also acts as a safety barrier between the high-pressure propane tank and the heating appliance.

In short, it brings the pressure of the propane down to a safe level. If the pressure is too low, the grill may not heat up. If it is too high, it may cause a flameout (or worse).

The regulator is bound to a propane tank to manage the gas flow to the burner of your grill. The higher the gas flow, the larger the flame, and thus the more heat. If the gas flow is low, the flame will be small, and the amount of heat will be low.

In addition, the regulator has what is called a bypass, which is a plastic mechanism that cuts off the gas supply when there is no pressure in the hose extending from the grill. This can be caused by a gas leak or by leaving the burners on for a long time.

All BBQ gas grills have a regulator, which, as the name implies, regulates the flow of propane gas. The regulator has a built-in safety mechanism called a bypass valve. This bypass valve system sits between the regulator and the propane tank.

Usually the system is in a locked state. This is the activated or tripped state of the safety mechanism. In some cases, this is caused by gas leakage, but in most cases, it is due to the user using an improper ignition method.

The safety device of gas regulators consists of a ball and a spring. The pressure from the propane tank pushes the ball against the spring. When it happens, a gas flow is established. If there’s a leakage or burners are left open, the reverse flow of the air pressure doesn’t let the ball displace from its position inside the regulator. As a result, propane from the LPG canister can’t pass through the safety device.

If you don’t light the grill in a certain way, the safety device will mistake it for a leak and reduce gas flow from the canister to less than 10% of normal. This condition is called “bypass.” When the gas supply is reduced, the grill cannot be brought up to its normal temperature, and in some cases, the grill will not light.

Wait a few seconds for the hose to build up pressure before doing anything else. This pressure will push the equipment in and give you the “all clear” to operate normally. It should be noted that allowing the pressure to build-up is the most significant part of the entire process.

After a short wait, turn the appropriate burner to start/high and press the igniter button to ignite, just as you would with a normal grill. The actual ignition method will vary depending on your particular model. Please refer to your owner’s manual for details.

Light all main burners, turn the temperature to high, and close the lid. After about 10-15 minutes, if the temperature reaches 500-550℃, the liquid propane grill is working properly.

Basically, the key is to always turn off the burner before you turn on the liquid propane tank valve. If you turn on the burner first, the gas won’t be pressurized in the gas line, and the bypass will be activated.

To the system, it looks like there is a leak, so the bypass is activated or triggered. (Even if there is no gas leak, the system will think there is a leak because of the low back pressure.)

Side note:If used in the wrong order, the regulator will trip. Turning the burner on first will empty the propane line, resulting in low line pressure.

In most cases, performing a propane regulator reset will get the job done for you. However, sometimes, especially if there’s a severe issue with the propane regulator, resetting the regulator isn’t the option, and you’ll have to replace it.

It’s not necessary the failure to ignition can indicate that you need to reset the regulator. In fact, low temperature can also be the reason for propane regulators in need of a reset.

Also, please note that the flame should always be blue. If it’s not and you’re constantly getting the yellow flame, it’s problematic, and you can go ahead either clean your burner tubes or reset the gas regulator.

If the gas regulators continuously trip, there may be a leak in the hose. Close the valve on the gas tank and disconnect the regulator and gas line from the propane tank. Immerse the regulator in a solution of soap and water, then attach the regulator and hose back to the gas container.

Make sure the burners on the grill are “off,” and the valve on the tank is turned on. Soap bubbles will indicate the location of any leakage in the regulator or hoses. Replace the regulator or hose as necessary.

Now that we know what the problem is with the propane regulator, let’s try to come up with a solution. Of course, this assumes that you have checked your gas container to see if it simply needs to be replaced with a new propane tank.

Slowly turn on the supply from the fuel container by rotating the valve counterclockwise.Make sure you do it veryslowlyto avoid tripping the regulator. It should take  20-30 seconds.

When it’s about cooking on your grill, a tip-top gas regulator can guarantee the constant flow of heat for your BBQ and save you from distress. The regulator reset call, however, needs the right identification of the problem first. It might be your grill regulator demands to be replaced, and working on the valves can be of no help. You can take the right steps by following this quick guide. Hence, if your grills fail to serve your outdoor cooking with sufficient temperature, follow this expert guide on how to reset the gas grill regulator.

If your Mosquito Magnet® fails to start, it may be the result of poor gas flow from the propane tank through the regulator to the trap. The Reset Tool has been designed to reset the internal mechanisms of the propane regulator and release any back pressure from your tank.

It is recommended that you do this procedure every time you connect the regulator to the propane tank to avoid any difficulty in the start up process.

My understanding is the safety is in the regulator, if there is to large of a flow of gas it trips and restricts it. That is why you need to turn the tank on with the burners off. If you can"t get the appliance to work shut the tank off while the burners are on then turn them off and the regulator should reset.

I thought that is why they went to the outside threads, because the old tanks with the internal threads you could turn on and gas would flow. I was always taught to open it and close it fast to make sure any dirt got blown out. when they went to the external thread the tank won"t flow unless it is hooked up. I never investigated what is in there that the new hook up triggers to allow the gas to flow.
