8.4.2– TROUBLESHOOTING
The following malfunctions are acknowledged by the electronic controller:
"P1" CABINET sensor error. The error is triggered during the normal refrigerating cycle just a few seconds after
-
the sensor starts to malfunction. The cycle is not stopped, but the compressor operates on an alternating basis
(ON/OFF) to ensure that cabinet temperature is maintained. The error message disappears just a few seconds
after the sensor starts operating regularly again. If the error persists, before replacing the sensor, first check the
connections.
"P2" EVAPORATOR sensor error. The error is triggered during the normal refrigerating cycle just a few
-
seconds after the sensor starts to malfunction. The refrigerating cycle is not stopped by the error and the
compressor operates regularly, but the subsequent defrost cycles will be carried out on a time basis rather than
according to the temperature given by the actual sensor. The error message disappears just a few seconds
after the sensor starts operating regularly again. If the error persists, before replacing the sensor, first check the
connections.
