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.

One intriguing thing about electricity is that a change in temperature can affect how well it passes through certain materials. For example, a lot of research revolves around ​superconductors​ – materials that offer very little resistance to an electrical current – but superconductors typically must be heavily chilled to work.

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.

Note that we are currently reevaluating all of our guides to ranges and our advice on buying them, including learning everything we can about induction stoves and cooktops. This is largely due to changing city and state regulations (video) on installing gas kitchen equipment and to the 2022 Inflation Reduction Act, which introduced the first federal consumer rebates on electric kitchen appliances. However, if you need to buy a new gas stove now, the picks below are all available. And they’re made by companies we trust, so we remain confident in recommending them.

The cooktop on the GE JGB735 is about as good as you’ll get for the price. It has a stronger pair of power burners than you usually find, and both are situated in the front row (where they’re easy to reach) and covered with continuous grates. The oven is big enough to comfortably fit a hefty, 26-pound turkey or a spacious, 15-by-20-inch baking stone. The JGB735 also has a high-heat cleaning mode as well as a convection mode—for quicker, crispier, evenly done cooking—and an air-fry setting. The previous version of this range, the JGB720, received largely positive reviews and seemed generally reliable, so we’re optimistic about the current model. We do wish the oven came with a third rack.

The Frigidaire Gallery GCRG3060A has a build quality that feels almost as sturdy as that of the GE JGB735. Plus, the Gallery has a third oven rack. Like the GE JGB735, the Frigidaire Gallery has an air-fry setting and a number pad (so you can more easily control the oven). We don’t think the Gallery’s cooktop is as versatile, since its second-strongest burner isn’t all that strong, and it sits in the back row (though some may prefer this layout, to keep hot pots away from kids, for instance). But the Gallery is a good alternative to the GE JGB735, if that model is sold out.

If you just need an inexpensive stove that works, the Whirlpool WFG320M0B offers the best balance of features for a low price. It has one of the better cooktops in this price range, with a stronger power burner than those on most competitors and continuous cast-iron grates (especially uncommon at this price). The oven has a similar capacity to what you get in a pricier stove. But it doesn’t have convection, self-cleaning, or a number pad for control (the lack of these are typical with budget stoves). We found it to be well built, and it has a strong average user rating.

This double-oven range has one of the largest lower ovens we’ve seen in this quirky product category, and it has one of the strongest power burners we’ve seen on any freestanding range.

If you’re looking for a double-oven range (read more about them here), we suggest the GE Profile PGB965. It has best-in-class cooking features, including an air-fry setting and a cooktop that’s as powerful as any we’ve seen on other freestanding ranges. And its lower oven fits bigger birds and roasts than other two-oven models can accommodate.
