Sometimes fault codes will appear with no
apparent cause. These codes and their
symptoms include:
• F1 - If the food is a large cold load that must
cook over 5 minutes, the temperature of the
cavity may not rise fast enough to change the
thermistor resistance very much. The control
believes that the thermistor is not responding
because it is open, and thus displays the F1
code. This can be cleared at the end of the
cycle and cooking will continue.
• F4 - If there is an electrical surge or excessive
line “noise” within the home, it could cause F4
to display on the control. The sensor will
remain inoperable until the control is reset.
This can be done by removing power (turning
off the circuit) to the unit for 1 minute.
NOTE: Replacing the humidity sensor will not
cure this situation if it was due to electrical
“noise.”
• Interior oven lights stay on or off and do
not respond to key commands - This is also
caused by electrical surge or excessive line
“noise.” Remove power (turn off the circuit) to
the unit for 1 minute. Replacing parts will not
solve the problem.
