Tests to be performed:
Detach the connectors and
effect measurement on the
component (fig. 9):
- across connectors 3 and 5
the circuit must not be open
(the resistive value should
be measurable).
- across connectors 4 and 5,
the circuit must be open (the
numbers are printed on the
component).
Is the door safety interlock
OK?
To check the wiring (with the door
open), measure the following
wiring connectors (fig. 4):
- between wires J1-3 and J1-1, the
circuit must NOT be open
(measure the resistive value of the
PTC).
- between wires J1-3 and J1-2, the
circuit must be OPEN.
Replace the door
interlock and
restart the
diagnostic cycle
to check for
further alarm
conditions.
Check/replace the wiring and restart the diagnostic cycle to
check for further alarm conditions.
Replace the door locking device.
Does the appliance function
correctly?
Is the door locking device securely
anchored to the latch?
YES
Replace the door latch or the
door.
Replace the circuit board and
restart the diagnostic cycle to
check for further alarm
conditions.
If there are traces of
burning on the circuit
board, refer to page 59
