The pilot light is lit, but the oven will not heat up when set on temperature ( the oven is a magic chef in wall gas model).
We would need to have the model number to be able to assist properly but most likely the thermal couple is what is causing the unit to not heat.
Oven takes a very long time to preheat, doesn't hold temperature and can smell gas can't hear oven kick on
Answer Mitzi, The first check needs to be at the bake burner igniter 74007498. A weak igniter can cause all the symptoms as you described. A properly operating igniter will usually glow "white hot" in 60 seconds and draws 3.2 to 3.6 amps which is required to open the safety valve. An igniter that glows orange or red produces approximately 2.8 to 3.0 amps and cannot open the valve properly, if at all.
It takes 25 minutes for my oven to preheat and after 30 minutes the internal temp of any thing is only about 155 degrees. Whill it is preheating the flame will go on and off.
Answer Hello Rocky. 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
Oven ignites with good flame for a few seconds then goes out and comes back on with small flame.
Answer Hello Joe. That sounds like a pressure regulator or gas valve issue, if the flame is to small to heat properly.
Oven Op Panel shows correct temp, but actual temp is much lower. Checked resistance on temp sensor, it was 1107 ohms at ~70 degrees. It appears correct. What else could be wrong?
The oven sensor should be at 1090 ohms plus or minus 10 percent at 77 degrees. If the sensor is checking ok then you would want to check the wiring from the sensor to the control. If wiring checks ok then you will want to check the elements to ensure that they are getting proper power and check to make sure that neither of the elements are bad.
