Fan Motor; Bucket Switch - Whirlpool AD70USS Manual

Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.

FAN MOTOR

Refer to page 3-8 for the procedure for ac-
cessing the fan motor.
1. Unplug dehumidifier or disconnect power.
2. IMPORTANT: Discharge the capacitor by
touching the leads of a 20,000 ohm resis-
tor to the capacitor terminals.
3. Disconnect the fan motor wires from the
capacitor terminals.
4. Disconnect the remaining fan motor wires
from the mechanical or electronic control
terminals.
5. Set the ohmmeter to the R x 1 scale.
6. Touch the ohmmeter test leads to the in-
dicated motor wire connectors. The meter
should indicate as shown in the following
chart:

BUCKET SWITCH

Actuator
N.C.
N.O.
Refer to page 3-10 for the procedure for ac-
cessing the bucket switch.
1. Unplug dehumidifier or disconnect power.
2. Disconnect the wires from the bucket
switch terminals.
3. Set the ohmmeter to the R x 1 scale.
4. Touch the ohmmeter test leads to the
indicated switch terminals. The meter
should indicate as follows:
COM and N.C. = 0 Ω
COM and N.O. = Infinite
5. Press the actuator and the readings in
step 4 should reverse:
COM and N.C. = infinite
COM and N.O. = 0 Ω
