Was bedeutet der Fehlercode?
The combustion preheater module (CPM) has registered a signal from the flame sensor that is too high. The cause may be a short to supply voltage in the cable, poor contact or a damaged flame sensor. The heater cannot be activated until the code has been cleared.
Mögliche Ursachen
- The cable between the CPM and the flame sensor is shorted to supply voltage
- Contact resistance, oxidation or loose connections
- Damaged flame sensor
Was Sie tun können
- 1Clear the code and check that it does not return when the heater starts
- 2If you have a diagnostic tool, read whether a flame was detected after a completed heater run and compare it with what the heater did
- 3Disconnect the connector at the flame sensor and check that the contacts are secure and free from oxidation
- 4Use 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
- 5If the fault returns, have a workshop check the flame sensor and the wiring to the CPM
Symptome, die Sie bemerken können2
