Light in oven does not turn off

Thank you for your inquiry, Lucie!

From what you have described your Frigidaire oven lock is stuck open and you are receiving error codes "F9" and "DR". The "F9" error code stands for runaway temperature (overheating). This could be an issue with your RTD (Resistance Temperature Detector) or the EOC (Electronic Oven Control). I would recommend performing a reset on your oven and you can do that by disconnecting from your oven for ten minutes. The "DR" code means that the door is not closed or the door latch is not recognizing the door is closed. This could be an issue with your door latch or control panel. If the reset does not help correct your issues I would recommend having a professional technician out to perform a proper diagnosis and repair. Best of luck! -Matt

If you remove the knob, you will see the very center of the male part the know attaches to has a small flat head screw in the middle of it. Buy turning this screw in and out, you are micro adjusting the temp when the oven cycles on and off. Its best to have a digital thermometer set up within the oven so you can see exactly when the oven cycles on and off. It's going to fluctuate about 20-30 degrees. So set your oven to 350, let it turn on and watch carefully when the red light shuts off it should be between within 30 degrees from where you set it, up or down. If its too low,turn in( could be out, I forgot) the screw in the center of that know with a mini flat head screw driver. If you turn it and the light goes back on, you turned it up. If it does not go on in an quarter turn, you went lower. Once your digital thermometer matches up closely whith what your oven says, your good. 25 degrees isn't much to be gentile whith turning that middle screw, you could miss your mark and be off even more very easealy.

Stove will not turn off CHECK
Temperature Control Thermostat
If the oven won't turn off the oven thermostat is often the cause of the problem. The electrical contacts inside the oven thermostat can weld themselves together and then the oven won't turn off. If this happens, turn off power to the entire appliance at the household circuit breaker or fuse. The oven thermostat usually cannot be tested and must be replaced if defective.
Oven Control Board
The oven control board has a set of relays that turn on and off power to the bake and broil circuits according to the customer settings and sensor input. If the oven won't turn off it could be that one of the relays on the oven control board is shorted closed, providing voltage to the heating circuit. It can be dangerous if the oven won't turn off. Don't leave the oven unattended without turning off power to the oven.
Relay board:
Some ovens are equipped with a relay board. This circuit board has several relays which control the switching of electrical current to the oven heat source. If the oven won't turn off it may be that one or more of the relays on the relay board have failed. If this happens replace the relay board. The relays on the board are not sold separately. ALSO CHECK THE BAKE AND BROIL ELEMENT.
: I offer free advice bcuz God is so good!

I too have just had this problem. The door switch (top right corner) is broken and the oven thinks the door is always open. Chances are it won't heat up either.

hi gud day,do u think the gas is ok or every time u open is come out, or check ur control gas line valve maybe it close or authomaticaly close due to some laekage. chect it by smeling every turn on ur knob,but unplug the item b4 u do.

tnx gerbee

hi my name is mark, a service tech needs to check the voltage to the cook top. you will probably find improper voltage. check data plate for proper voltage should be 208v or 230v depending onwhere you live.

hot surface light is turned on by a auxiliary switch across the plate. it is possible that the switch has stuck in the closed position. it is also possible that the plate is not turning off. feel the plate and check if it is at all warm. if not, then the auxialuary switch is stuck closed. not dangerous. to fix means replacing the limiter which is the rod you can see across the plate. sometimes you can only get the complete plate with limiter which is a bit pricey

great fix
