Troubleshooting
Note:
• Refer to Operating Characteristics before
choosing a troubleshooting procedure.
• Refer to Schematics.
• Refer to Component Locator Views.
Compressor Knock
Capillary tube not taped to suction line. Check
to see that capillary tube is clipped to the suction
line near the dryer.
Low or No Cooling
Check for the following problems:
1.
Condenser dirty/clogged. Unplug unit and
clean condenser and underside of refrigerator.
2. Interior lights remain on. Check to see that
interior lights turn off when door switch is
pressed.
3. Door gasket does not seal. Check for
damaged or leaking door gasket.
4. Compressor does not operate. Go to
Compressor Does Not Operate
troubleshooting.
5. Condenser fan does not operate. Go to
Condenser Fan Does Not Operate
troubleshooting.
6. Evaporator fan does not operate. Go to
Evaporator Fan Does Not Operate
troubleshooting.
7. Evaporator is frosted. Go to Defrost System
Check.
8. Duct is clogged between freezer
compartment and fresh food compartment.
If fresh food compartment is warm and freezer
is normal or too cold, duct (diffuser) may be
clogged. Duct is accessed by removing air
tower.
9. Refrigeration system faulty. Go to
Refrigeration System Check.
Compressor Does Not Operate
Check for the following problems:
Note: The defrost control must be in cooling
mode to operate the compressor (provide
115 VAC to the compressor overload). It may be
necessary to manually rotate the defrost control
to cooling mode before checking for voltage at the
compressor overload.
1.
115 VAC not present at compressor
overload. If 115 VAC is not present at the
compressor overload, check for an open
temperature control or an open defrost control
(cooling mode - terminals 3 and 4 are closed).
Note: The compressor, condenser fan, and
evaporator fan should always operate at the same
time. If the condenser fan is operating, the
temperature control and defrost control
are OK.
2.
Overload open. High heat or high current
draw will cause the overload to open. The
overload should close when the temperature
lowers to normal or when normal current draw
is present.
3. PTCR relay open.
4. Run capacitor faulty.
5. Open wire or faulty connector. Refer to
Schematics.
6. Compressor motor faulty. Check resistance
across the compressor motor. Refer to
Schematics for resistance values.
7. Compressor mechanically stalled.
Condenser Fan Does Not Operate
Check for the following problems:
1.
Condenser fan faulty.
2. 115 VAC not present at condenser fan.
The compressor, condenser fan, and
evaporator fan should always operate at the
same time. If the compressor is operating, the
temperature control and defrost control are
OK.
3. Orange wire open on neutral side of
condenser fan. Refer to Schematics.
