Probe 3 Faulty identifies the condenser probe alarm which flashes on the display
and is recorded in the Service menu, under Alarms.
The alarm may be caused by the interrupted or out of calibration "NTC probe
condenser" or by the board analogue input
Check probe connection
Access the electronic board, “S.COND.” connector
Check the probe connection to the board.
If the connection is loose, connect the probe again and check that the alarm does not appear on display
If there is oxide on the connection, remove it and check that the alarm disappears
If the alarm remains, invert the condenser probe with the air probe
If the Probe 1 Faulty air probe alarm flashes on the display, the
condenser probe is faulty
replace the probe
If by inverting the condenser probe with the air probe the alarm remains, it means that the
problem is the analogue input of the electronic board
replace the board
It is possible to identify the cause of the alarm by checking the probe with the
multimeter
If, with multimeter set in
Ω
, the probe is interrupted or the
resistive value is not within the range of use (see tab. NTC)
replace the probe
If, with multimeter set in
Ω
, the resistive value of the probe matches
the temperature inside the cabinet (see tab. NTC)
replace the board
