Electrical Shock Hazard

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:

Motor	Motor	Capacity	Test	Resistance
Part #	Type	(Pints)	Lead	(Ohms)

1188409	1-Speed	25	Wh-Bk	161	±20%

1188411	2-Speed	35 & 50	Wh-Or	142	±20%
1188411	2-Speed	35 & 50	Wh-Bk	118 ±20%

1188413	2-Speed	70	Wh-Or	65	±20%
1188413	2-Speed	70	Wh-Bk	50	±20%

BUCKET SWITCH

Actuator

N.C.

N.O.COM

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
