This gas oven repair guide will walk you through the steps in repairing your gas
oven. These are the same steps I take in repairing ovens professionally. So read
each section carefully and your oven will be repaired in no time. Note that if
your oven uses a pilot light then this page will not help you. There are a few
things that go wrong with gas ovens that you can repair yourself easily, but I
don’t recommend you change anything that requires you to disconnect the gas
lines because this can be very dangerous. These repairs are best left to a
professional. Below are repairs that are safe for do-it-yourselfers.

If your gas oven is not heating, the igniter is the most likely the cause. This is a simple gas oven repair. To check the igniter, remove the storage drawer and the bottom of the oven (only if you are working on the bake burner). Now turn on the oven and observe, from a distance, the burner that is not heating. In a minute or so the igniter should glow red. If not, unplug power from oven. Then unplug the igniter and using your ohmmeter ,check to see if you have continuity between the two wires going to the igniter. If you don’t have continuity, replace the igniter. If you do have continuity, read the section on gas valve. If you turned on the oven and the igniter did glow red, the igniter still is most likely the problem. You have to have an amp meter to check for sure, but I would not suggest buying an amp meter just to check this because 99% of the time its going to be the igniter. So I suggest just replacing the igniter. For those of you that already have an amp meter, clamp the amp meter on one of the wires going to the igniter then turn on the oven. If your igniter is round, the amp meter should read 2.5 to 3.0. If you have a flat igniter then the amp meter should read 3.4 to 3.6. If the amps are not in this range, the gas valve will not open to release gas to the igniter. To repair this, replace the igniter. Round and flat igniters can be purchased at AppliancePartsPros.com.
This is another simple gas oven repair and it’s one thing you may need to check before you change any parts. The burner has a lot of small holes that connect the flame all the way around the burner. If one of these small holes is stopped up, the burner will not light properly. To repair this, simply use a large needle to clean each hole out. Note that this is not a very common problem but if this does fix your oven, it will save you a lot of money.
If your gas oven is not heating, the gas valve may be your problem. If your igniter isn’t bad then the gas valve is the problem. But this is not a simple gas oven repair and it’s best if this is changed by a professional because if the gas valve leaks it can be a major fire hazard and you have to adjust the valve to the kind of gas you are using.
