No Cooling at All Lights On Hot Compressor
The compressor is hot to the touch, but it is not cooling properly.
It is first necessary to determine whether the compressor
is off on the thermal limit (mounted inside the compressor connection
box) because of ambient temperature conditions or if it has an
internal restriction or another system problem. The thermal limit is
sensitive to both current and temperature overload. For instance, a
restriction in the freon system may cause high compressor current and
cause the limit to break the circuit. (See Freon System Failures in Manual 7: Refrigerators and Freezers.)

Spin the condenser cooling fan blade, it should spin
freely and slowly drift to a stop. Remove any obstruction such as a
dead mouse or loose insulation and give the compressor several hours
to reach proper operating temperatures. Using a fan to blow air over
the area will speed up the process.
The surest way to test a condenser fan motor is to
connect a test cord directly to the motor itself; this is also a fast
way to cool off a hot compressor. Forget oiling a condenser fan
motor, replace it. They are universal and any two-watt clockwise
condenser fan motor will fit fine.
Note: On many brands, the cooling fan operates only
when power is supplied to the compressor. SubZero is an exception:
the fan runs 24 hours a day. On older GE refrigerators, the cooling
fan is wired in after the compressor overload. In other words the
cooling fan shuts down whenever the compressor gets too hot. (This
illogical logic has been changed on newer models.)
-
The condenser is the group of black coils nestled
underneath the refrigerator. Typically, cool room air is sucked into
the right-front side, across the condenser and compressor, and warm
air blows out the left-side. Just ask the cat, he only sleeps on the
left-side. Is the condenser clogged with lint and animal hair?
