F5 = Watchdog and hardware conflict
Loss of relay drive circuit
If this fault code cannot be cancelled, replace the oven control (also
called clock or ERC).
Sometimes just unplugging the sensor quick connect and cleaning the corrosion in it fixs the problem. Replace control board (also called ERC or clock).
F5 indicates
the control felt a loss of power. I generally check the oven sensor for
resistance (1040-1090 Ohms @ 770F). If the sensor is within normal
limits, the control is bad. Replace clock (ERC).
(see the following link) although it can sometimes be
caused by a failed oven temperature sensor. The sensor should be
checked before replacing the control. It should read about 1100 ohms
when at room temperature.
