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.
