Hva betyr feilkoden?
The CPM has registered a break in the cable to the combustion fan, so the signal is missing. The cause may be a break in the cable or poor connections, such as oxidation or looseness. The heater cannot be activated until the code has been cleared.
Mulige årsaker
- Open circuit in the cable between the CPM and the combustion fan
- Contact resistance, oxidation or loose connections
Hva du kan gjøre
- 1Clear the code and try starting the heater again
- 2If you have a diagnostic tool, activate the combustion fan and listen for a buzzing sound; if it does not start, the fault is probably permanent
- 3Check that the connectors at the heater and at the fan are tight and free from oxidation
- 4Use a multimeter to check that the cable between the heater connector and the fan is intact; a break means the cable must be replaced
- 5Check that the fan wheel is not jammed and turns freely
Symptomer du kan merke2

Hva feilen kan påvirke1
