Temperature control I have a GE Spectra gas oven.If you set your bake temp to lets say 350,the oven will heat to that temp but in time several minutes the temp will drop.The diplay will still say 350.If you turn off oven and restart the display will read a lower temp ie 265 and climbing back to 350.The oven will not keep the temp set for baking.There are no codes displayed.

It could be a bad temperature probe

Hello & Welcome to FixYa

This indicates an open/shorted oven temperature sensor and to solve this problem the sensor needs replacement. If you wan to be sure before replacing the sensor then you can test it with a voltmeter for around 1100ohms....if it reads more then this then it needs replacement however, if the reading is around or less then 1100ohms then it is the control board that needs replacement. Please get back to me if you have any other questions.

my oven is propane. if i set it for say 350 it will heat up then drop down to 150. it won't hold the temp.

18 mins from room temp to 350 is factory standard,
you may need to calibrate the range, most now adays come factory set at -25 degrees for safety
depending on your model number in your instruction manuel should be a part about recalibrating it sounds like your about 25 degrees off

you need to calibrate the oven.

the second in the list is your solution

1. Do both coils get red hot? Try with bake @ 400F, then with broil to be sure. I recently had a bad lower bake coil, but the oven got hot slowly since the broil top coil comes on periodically to even up the heat in the oven. Replacing the lower coil was easy, about a 15-min job, but I had to pre-tap the screw holes on the coil terminals since my oven had extremely short wires.

2. If the coils are ok, the problem may be with the thermocouple or control board.

I have the exact problem. We had the ignitor replaced 2 already and it works for 18 months and stops. Occasionally, it the oven won't even start to heat. I am ready to throw it out.

Puzzeled, usually when there is a stuck or shorted keypad there will be an error code. First let's see if we can tell if we are in Centigrade or Ferenhiet. Press the bake and broil button together for 2 or 3 seconds. SF should appear in the display. Press the broil pad again and C or F will be displayed. Toggle to F and press start. See if that was the problem. If not try to increase the speed of the + and - keypads. Press bake and broil together for 2 seconds until SF displays. Press the + keypad increase the speed of the control. It should toggle from 1 to 5, 5 being the fastest. Press start and see if that works. If niether works..then have someone remove the keypad ribbon cable from the control board and clean the ends with an eraser. See if that solves the issue...Catriver..post back and let me know.

Replace Electronic Range Control (ERC)and touch pad sorry .
