The overheating switch of the oven chamber is off because the oven
chamber temperature has risen above 350°C/662°F. Press the Q1 button
(cavity high limit) at the bottom of the oven to reset the switch. If the
oven comes with two fan motors, there are 2 overheating switches.

see if the overheating thermo switch
has tripped. Reset the switch.
2 Test whether the fan is running and
whether the solid state relay is
working properly.
3 Check the cable and the cable plugs.
Error Code 5
The fan motor is too hot (above 120°C/248°F). Let the motor cool off for
about 20-30 minutes and then try turning it on again.
1 Go to the test menu (main alarm) to
see which information is displayed.
2 Check the cable and the cable plugs.
3 Check the door sensor since 5VDC
may affect the overheating circuit.
Check the fan motor windings.
