This GE oven recently began failing at sustaining the temperature set for baking. The oven when set will increase steadily to the temperature set, then when reached, it will beep to signify it is at bake temperature. Once this happens the display locks in the temperature set and the display does not deviate. Unfortunately, the temperature in the oven will start to drop and the oven will not reheat to the bake temperature set. We discovered what was wrong by cancelling the bake sequence and resetting. When you do this you re-initiate the display to show the actual temperature in the oven so you can watch it build. Recently it always displays about 80 to 100 degrees lower than the temperature set, but it always successfully buids back to set temp before locking display and dropping temperature. My initial advise from browsing the Q&A section on this site was to change the temperature sensor(probe). I received the sensor yesterday and changed it out. To my dismay this did not solve the problem (I now have a $95 oven temperature sensor which I don't need). Please advise on which part requires changing in order to resolve the problem with this oven?
ANSWER Hello Malcolm,
Based on the information provided you will want to check your sensor wires to make sure that they are not shorting out. If the sensor wires check ok then you would want to replace the control board. To check sensor wires you will check with sensor wires disconnected from board and from sensor. Check continuity through the wires. 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
