E72: Drying NTC sensor on condenser faulty
E72
Ohm value of the NTC out of limits
E72
Tests to be performed:
Measure the value of the NTC
sensor across contacts J7-3 and
J7-4 of the WD board connector.
- see fig. 32 -
Is the value correct?
(between 5.7 and 6.3 KΩ at
20°C
)
Detach the connector
and measure the NTC
sensor directly.
Is the value correct?
- see fig.33 -
Replace the NTC
sensor and restart the
diagnostic cycle to
check for further
alarms.
Measure across terminals J7-3,
J7-4 of the connector and the
structure of the appliance – see
fig. 6 -
Is there any current leakage?
Check/replace the wiring and restart the diagnostic
cycle to check for further alarms.
Replace the WD board and restart the diagnostic
cycle to check for further alarms.
Check/replace the wiring and
