Hva betyr feilkoden?
The CPM has logged that the heater ran past its permitted ventilation time. The heater is then deactivated and the code is set. The cause may be a damaged combustion fan or a damaged flame sensor.
Mulige årsaker
- Damaged combustion fan
- Damaged flame sensor
Hva du kan gjøre
- 1Check that the air intake and exhaust outlet on the heater are not blocked, for example by leaves, snow or dirt
- 2Make sure the flame sensor has no soot build-up and is not damaged
- 3Clear the code and start the heater again to see whether the fault returns
- 4If you have a diagnostic tool, read the flame sensor temperature in live data; if it does not behave as it should, the flame sensor is suspect
- 5If the fault remains, have a workshop check the combustion fan and measure the flame sensor resistance
Symptomer du kan merke1

Hva feilen kan påvirke1
