It sounds to me that your door switches aren't working.Your oven is protected by a couple of switches that engage when you open or close the door.They control a couple of safety features and also your interior light.One of them seems defective.

Hi,
The unit has a temperature sensing device that turns on the fan if it gets too hot...if it is very hot in your house it could turn this on...
If it is not overly hot then the thermistor or the main control board have gone bad and are reading an incorrect temperature...

Hello ediben11.

If your oven's bake or the broiler heating elements won't heat but the range burners still work;the clock may be set for a timed or self-cleaning cycle. So,make sure to check the clock buttons and the knobs are set properly.
*If your clock has a knob that says "push for manual" then push the knob in after that, try the baking and broiling elements again.

*If it still does not work properly, you may have a defect in the thermostat/selector switch/common wiring.

*If the oven does not have a separate bake or broil selector switch; then the thermostat is probably the problem. It is not easy to check the selector switch or thermostat for proper operation. If you suspect a problem in this area, call a qualified appliance repair technician.

Hope this helps.

NOT THAT I'M AWARE OF . YOUR UNIT SHOULD HAVE A SWITCH TO TURN ON AND MUST BE TURNED ON MANUALLY

ok here is the result to searching GE the answer to thew code.

Open oven temperature sensor (circuit) (over 2700 ohms) or, shorted oven temperature sensor. Could be a result of:
· contamination on terminals
· pinched wire in oven temperature sensor circuit
· cold solder joint on control. · Disconnect power to range and remove oven temperature sensor connector from control.
· Measure oven temperature sensor resistance at oven temperature sensor connector (take care not to damage terminals in block) - Should read 1100 ohms at room temperature (approx 72 degrees F).
· Measure each oven temperature sensor lead from connector block to ground. If shorted, look for pinched or cut wire in oven temperature sensor circuit.
· Check connector terminals - Look for deformed or corrosion on terminals. Repair or replace.
If all above is ok replace control.

You are right. f4 means shorted oven temperature sensor (RTD). Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.
