The refrigerator uses a single speed reciprocating
compressor.
Compressor Diagnosing
Check the resistance of the compressor windings.
• S to C
: ~6 ohms
• R to C
: ~4 ohms
If the resistance is not correct or a winding is
open or shorted to the case of the compressor,
replace the compressor.
The compressor can be turned on using Service
Mode Test t9. Voltage can be checked at the
main board and overload/relay wiring.
Main Board
• J19 pin 1 (
black
) to J7 pin 9 (
orange
): 120
VAC
Overload/Relay Wiring
• Orange
to
black
: 120 VAC
NOTE:
If voltage is present to the overload/relay
verify that the overload and relay are good prior
to replacing the compressor.
Compressor Removal
1. Remove the machine compartment cover.
2. Disconnect the compressor electricals (relay/
overload and capacitor).
3. Remove one 1/4 in. hex-head screw to
disconnect the ground wire from the left side
of the compressor.
4. Follow the recovery procedure and
disconnect the suction and discharge lines.
The capacitor plugs directly into the PTCR
relay/overload mounted on the left side of the
compressor and is secured with a bale strap.
Capacitor Diagnosing
1. Discharge the capacitor by simultaneously
touching both terminals against the metal
back of the refrigerator.
2. Set multi-meter to ohms. Place meter
leads across the capacitor terminals. The
resistance should climb until it exceeds about
310k ohms. Then the meter will read OL.
(This can be repeated, but the capacitor must
be fully discharged each time, before testing).
Capacitor Removal
1. Remove the machine compartment cover.
2. Follow
PTCR Relay/Overload Removal
steps from the previous section.
3.
Pull the capacitor straight off of the PTC relay/
overload.
