7.1 Fans
7.1.1 Condenser Fan
The condenser fan is used to force air over the condenser coil. The condenser fan cycles on and off si
-
multaneously along with the compressor.
1)
Make sure that the motor shaft turns freely. The blade can be turned in either direction to verify
that the shaft is not seized or the blade binding. Watch the blade and listen for any noise that
might indicate a problem.
2)
Check resistance between the terminals of the motors power cord. Replace the motor if the wind
ings are shorted (open).
3)
Check for continuity between each lead of the power wires to the motors casing. If the motor is
grounded there will be a continuity reading.
4)
Check amp draw. Typical current draw will be approximately 0.15 without any resistance on the
fan. A current draw exceeding 0.19 will be an indication that the motor or fan blade is not turning
freely.
7.1.1.1 Removal of the Condenser Fan Motor
1) Remove all screws around the perimeter of the cabinet. Do not remove the screws in the slotted
area. (See figure 12.3)
2) To loosen the rear of the mechanical assembly, remove both hex screws at each lower back corner
(See figures 12.4).
3) Remove the two Phillips screws and remove the front grille (See figure 12.5).
4) To loosen the front of the mechanical assembly, remove both Phillips screws that secure the front
corners (See figure 12.6).
5)
CAUTION
, (See figures 12.7 & 12.8) before sliding out the mechanical assembly please read the
following carefully. To avoid kinking of any system tubing do not slide the mechanical section
forward farther then 6” maximum. Doing so may kink any or all of the following: discharge line
at the compressor, suction line at the compressor, suction line as it exits the rear of the cabinet.
6)
Remove condenser fan by removing the four screws on the fan mounting base plate.
7)
Remove the tinnerman clip from the motor shaft and remove the fan blade and rubber silencer.
8)
Remove the fan motor from the bracket.
9)
