E41: Door open (device with 3 connections with flange)
E41
Checks to perform:
Fig. 9
To check the wiring, with the door
open, measure on the following
wiring connectors:
- between wire J5-2 and J5-3, 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.

Detach the connectors and
measure on the component
(fig. 9):
- between connectors 3 and
4, the circuit must not be
open (measure the
resistance value of the PTC).
- on the other hand, between
connectors 4 and 5, the
circuit must be open (the
numbers are printed on the
component).
