Forced defrosting (Measurement is impossible when
DEF-thermistor is set at 10°C or higher because
defrosting ends immediately)
After approx. 15 sec., the voltage
measured across
and
of CN5
on the main PWB is equal to supplied
voltage? (e.g. 240 V)
Disconnect CN5 from the main PWB. Measure the
resistance between
and
of CN on the wiring.
Check defrost heater wiring for loose
connection or disconnection.
Check cause of defrosting failure
· Check door packing
· Check mounting seal of E.V. cover Assy
