E73: NTC sensor on drying duct faulty
E73
Ohm value of the NTC out of limits
E73
Tests to be performed:
fig. 6
Measure the value of the NTC
sensor across contacts J7-1 and
J7-2 of the WD board
connector.- (see fig. 30) -
Is the value correct?
(between 4.7 and 5.3 KΩ at
20°C
)
Detach the connector
and measure the NTC
sensor directly.
Is the value correct?
- (see fig.31) -
Replace the NTC
sensor and restart the
diagnostic cycle to
check for further alarms.
Measure across terminals J7-1,
J7-2 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
