I tested the igniter at. 95 ohms. Oven bake was not lighting, but broil was. 120 volts at plug from board. Once apart the oven decided to light, go figure. It takes about 75-80 seconds to light from press of start. Does my ohms sound right, and what is an acceptable light time? It has been slow to heat up to temp. Thanks.
Answer Ryan, A resistance reading of 95 ohms is in range, But a resistance test is not the best way to test an oven igniter. The best way to test the igniter is to use a "clamp on" amp meter TJMA-600CF. with the meter clamped around one of the wires, as the igniter glows, there should be a 3.2 to 3.6 amp draw, and at that point the gas valve bi metal switch should open and release the gas for ignition and flame. On avarage it should only take 30 to 60 seconds, if the igniter is operating properly and drawing the correct amperage. If you can't get access to a meter, replace the igniter, 95 % of gas oven temperature issues are do to a "weak" igniter.
My ignitor, I believe is bad. It has 120 volts when on but no glow or heat. Also with no power it has no continuity. My ignitor has no connection that I can see like the one in your diagram. Do I snip connection and hard wire with ceramic nuts?
Answer Hi Joe. Never check continuity with the power ON. It is not safe and it will at least open the meter's fuse or you take a chance of blowing up a meter. The cold igniter ohms out from 75- 800 ohms. There will even be a physical crack in the middle of it. It needs to glow white hot for at least 30-45 seconds to open the gas valve. This part # is WB13T10045. Yes, the ceramic wire nuts should be placed as far away from the burner as possible. Thank you.
Oven not working. Broil works, but not bake. How do I access the area where the ingitor connects in the unit?
Answer Hello Liz. You will need to lift the bottom out of the inside of the oven. Some of these have two screws in the back holding them in. You will lift the back of the bottom first to remove the bottom. Once removed, you will be able to access the igniter WB13T10045. Hope this helps.
