Checks to perform:
To check the wiring, measure, with
the door open, between the following
wiring connectors -(fig.4)-:
- between J5-1 and J5-3, the circuit
must NOT be open (measure the
resistance value of the PTC).
- between J5-1 and J5-4, the
circuit must NOT be open
(measure the resistance
value of the PTC).
- between wire J5-1 and J5-2, the
circuit must be OPEN.
Is the system ok?
