Probe 1 Faulty identifies the air probealarm 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 thermostat" air probeor by the board analogue input
Check probe connection
Access the electronic board, “S.CAB” 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 air probe with the evaporator probe.
If the Probe 2 Faulty evaporator probe alarm flashes on the display, the air probe is faulty
replace the probe
If by inverting the air probe with the evaporator 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
