CHECKING THE DOOR SEAL: Open the
door and examine all four sides of the door
gasket for any tears. Feel the gasket for
brittleness and/or cracks. If the gasket
shows damage, then it must be replaced. If
no damage is observed, close the door and
check the seal between the gasket and the
cabinet for obvious gaps. Next open the
door and close it on a dollar bill. Slowly pull
the dollar bill out from the door. If the
gasket seals properly, you will feel tension
as it grips the bill. Repeat this test all
around the door. If the gasket does not seal
tightly, replace the gasket after first
checking the door for any sagging or warping.
SERVICING THE CONDENSER FAN:
Inspect the condenser fan motor by
removing the mechanical housing cover to
gain access. Unplug the unit. Clean the fan
blade, and turn it to see if the blade rotates
freely. If the motor binds, replace it. If any
damage to the blade is observed, unscrew
the retaining nut that holds the blade to the
motor shaft and pull the blade off the shaft.
Install a new fan blade, replacing any
washers, and tighten the retaining nut. To
test the condenser fan motor, disconnect
the wires to the fan motor. Using a multimeter set at RX10, touch one probe to
each terminal. The multimeter needle should show approximately 45 to 50 ohms
resistance. A lower reading indicates the motor is faulty and needs to be replaced.
Next, set the multimeter at RX1000 and touch one probe to the motor terminals
and the other probe to any unpainted metal part of the unit. If the multimeter
needle moves, the motor is grounded and needs to be replaced. To remove the
motor, unscrew the bracket that holds the fan motor to its housing. Slide the motor
out of the housing. Remove the fan blade from the old motor and attach to the new
motor, replacing any washers. Install the new motor in its housing by screwing the
bracket into place. Reattach the wires to the motor terminals and reconnect the
ground wire.
