Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- Damaged combustion fan
- Damaged flame sensor
Co możesz zrobić
- 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
