I've had the thermostat replaced 2x on this oven and it seems I need to again - is that cost effective, do you think? The oven doesn't reach the temps desired - they're @ 50-75 degrees below the knob setting. I have adjusted the screw on the inside of the knob to its max. but to no avail. This is the same symptom from previous times.Once upon a time I could cook above 450 and even broil but no longer.
So, is this an oven thermostat problem, an oven sensor assembly problem (if there is such a beastie in this oven), or an old oven in need of being replaced (since the thermostat alone sets me back $100 each time)?
Thanks for your help.
Answer Scott, Your Range is approximately 25 years old, But three thermostats in that amount of time is a bit strange or weird. Especially if they are all 50 to 75 degrees off. Your particular range does not have a sensor assembly, so there's no need to go in that direction. How accurate is the thermostat you're using to test your temperature(s) ? Are you using Nat gas or LP gas ? and is the range converted properly ? You may want to remove the oven burner and check all the venturi openings to make sure they are clear, and shake the burner to see if you can hear debris "rattling" around inside the burner. We're taking for granted the oven maintains the heat, and doesn't stop heating during a bake cycle. If it were to stop heating, or have a drastic drop in temp. this could indicate an issue with a weak oven igniter, or safety valve. If you should decide to respond to this please include an e mail address, so we can assist you with technical information that may be more helpful.
Ignitor glows but oven will not light. No gas flowing to oven. Range top burners work fine.
Answer Hello David. Test for 3.0-3.6 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.

the oven comes on with out any thing being ,being on and i smell gas and after a few mints it comes on and heats up with nothing being on
With the issue that you are having it sounds like the contacts on the oven thermostat are faulty and you would want to replace the thermostat.
The oven will not turn off.
Answer Hello lewis. If the off button is not working, you will need to replace the control board WB27T10469 on the unit.
Smell of gas from oven.
Answer Hello Ron. 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.
