I got error messages F1-1 and F3-1 when operating the upper oven. I was advised to change the temp sensor. The oven still gives the codes occasionally. Does this indicate the control board is failing? Are there any tests that I can do to verify the problem before changing the board?
Answer Hello Fred. It may be the touch pad or the board. F1: Temperature runaway. Membrane
switch shorted. Alarm is continuous, if
cancel key is pressed alarm will stop, if fault
still present alarm will repeat. If membrane
switch is disconnected the alarm will only
sound for 30 seconds and stop.
Correction: Test membrane switch and oven
sensor, if OK, replace control.
F3: Open or shorted sensor. The cancel key
resets the control and stops the alarm. If
fault is still present it will reactivate the
alarm when a cook mode is chosen.
Correction: Check sensor and wiring for
shorted or open circuit.
