|If your Gas Oven Will Not Broil Check The Following
If your gas oven is not broiling, the igniter is the most likely the cause. This is a simple gas oven repair. To check the igniter, 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 the igniter is still most likely the problem. If you turned on the oven and the igniter did glow red, the igniter still is most likely the problem. This video will walk you through properly testing an oven igniter. 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 2.6 to 3.0. If you have a flat igniter then the amp meter should read 3.3 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.
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 or thin wire 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. This is a very uncommon failure in most ovens. 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.
This is the last thing to check. If you have no power to the igniter when the oven is turned on to broil the main control is the likely problem. On glowbar style igniters if you have no reading and there is continuity of the igniter replace the main control. On ovens with electronic igniters (these are the ones that click) these ovens have a separate spark control module that sends the power to the igniter. This can be difficult to check but in general if you have no power reaching the igniter the spark module or igniter module (there are many different names for this part) would need replacing.
