Checks
Clear the error using ‘ERROR’
in service mode (*4*).
Is the connection of the con-
nector J50 (4-wire harness
under the counter mount)
good?
Let the fixing assembly to cool;
then, disconnect J50, and mea-
sure the resistance of the ther-
mistor. Is the reading as fol-
lows?
J50-1/-2 (yellow line):about
1388 k
J50-3/-4 (white line):about
3636 k
Disconnect the connector J4
(near the door switch assem-
bly), and check electrical conti-
nuity. Is there electrical continu-
ity?
Replace the fixing assembly. Is
the problem corrected?
Replace the fixing heater dri-
ver. Is the problem corrected?
