FAN MOTOR COMMON
30:1 O.H. FAN MOTOR
This error code will be shown if the control system detects that the input OH FAN MOTOR is
deactivated during program run.
The overheating protection is automatically restored. When the overheating protection is restored
the error code is automatically reset and the ongoing program will continue. A long press on the
control knob/start button will make the control system reset and the ongoing program will be ended.
The error code can be trigged if:
• The motor is very warm. Check that the vent holes in the motor are not covered.
If the overheating protection is not trigged, but there is still an error code:
• Check the harness, connectors and functions by reading the electrical schematic and by using
the SHOW INPUTS menu when the machine is in service mode.
