Line Fuse; Capacitor - Whirlpool R-94 User Manual

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

LINE FUSE

Main PCB
Refer to page 3-6 for the procedure for servic-
ing the main PCB.
1. Unplug the air conditioner or disconnect
the power.
2. Discharge the capacitor by touching
one lead of a 20,000
common (C) terminal, and the other
lead to each of the other two terminals
(marked FAN & HERM next to the termi-
nals).
3. Set the ohmmeter to the R x 1 scale.
4. To test the line fuse, touch the ohmmeter
test leads to the fuse clips.
The meter should indicate continuity (0 Ω).
5.
NOTE: If the fuse is open, check the fan
motor windings (refer to page 4-3) to see
if the motor is defective.
6. Replace the main PCB if there is no output
to the fan motor or compressor.

CAPACITOR

Refer to page 3-6 for the procedure for servic-
ing the capacitor.
1. Unplug the air conditioner or disconnect
the power.
2. Discharge the capacitor by touching
one lead of a 20,000
common (C) terminal, and the other
lead to each of the other two terminals
(marked FAN & HERM next to the termi-
nals).
3. Disconnect the wires from the capacitor
terminals.
4. Set the ohmmeter to the R x 1K scale.
5. Touch one of the ohmmeter test leads to
the common (C) terminal and the other
test lead to the FAN and HERM terminals.
6. The meter should indicate several ohms
and gradually return to infinity at both the
FAN & HERM terminals.
