My magic cheif oven is very old and needs replacing. Funding is low and the oven has gone out. The part 74002387 would fix the problem. Rather than replace with a new part, can I repair the existing one?
Answer Hello Regena. If the gas valve is bad, it will need to be replaced. You can not repair the old part. Test for 3.2-3.6 volts AC at the gas safety valve with the igniter turned on. If the voltage is there, you have a bad safety valve. If the voltage is low, you have a weak igniter and the igniter will need to be replaced. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
My oven doesn't maintain a constant temperature. It heats up then drops way below temperature before it finally kicks on and heats back up. Makes cooking times alot longer. I am suspecting gas valve, and wondering if there is a way to repair it or if I have to get a new one.
Answer Hello Dale,
This can be caused by the temperature sensor, the control, the ignitor, or the gas valve. I would start by doing a current draw check on the ignitor. With a clamp on amp meter clamped on one of the ignitor wires, start the unit and make sure the ignitor is drawing between 3.2 to 3.6 amps of current. If the amperage draw is low, the issue will be the ignitor breaking down during high heat conditions, If the current draw is safely in range, the next suspect will be the temperature sensor. It should read about 1100O at 70°F.

I replaced my igniter stove lights fine but after it's turned off a strong gas smell still comes from the oven. The gas smell is all the time no matter how long its been since the oven was used. Thanks!
You should turn the gas off to the unit and do not use it even for the surface until you replace the gas valve 74002387. Once the part has been replaced, check for gas leaks with a soap and water solution mixed as follows: One teaspoon of liquid soap to a gallon of water and mix well. There is so little pressure in the gas lines, if you mix the soapy water solution too thick, the soap will actually stop a gas leak until it drips off.
