E43 E43: Problems with the triac which actions the door interlock
Tests to be performed:
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.
YES
Replace the circuit board and restart
the diagnostic cycle to check for
further alarm conditions.
