Hva betyr feilkoden?
The CPM has logged a flame sensor signal that reads too high. The cause may be the cable being shorted to supply voltage, a break in the cable, poor connections or a damaged flame sensor. The heater cannot be activated until the fault code has been cleared.
Mulige årsaker
- The cable between the CPM and the flame sensor is shorted to supply voltage
- Break in the cable between the CPM and the flame sensor
- Contact resistance, oxidation or loose connections
- Damaged flame sensor
Hva du kan gjøre
- 1Clear the code and check whether it returns
- 2Disconnect the connector at the flame sensor and check that the contacts are secure and free from oxidation
- 3Use a multimeter to check that the cable from the connector to the flame sensor carries no voltage when the heater is off; if it does, the cable is shorted to positive
- 4Use a multimeter to check the cable is intact between the connectors; a break means the cable must be replaced
- 5If the fault returns, have a workshop check the flame sensor
