4. Replace side panels and restart unit.

5.3 Condenser Fan Motor

The condenser fan motor is sealed at the factory and needs no lubrication. The

motor can be checked in two ways; check for continuity, and check to see that

power is present at the terminal block or terminal strip.

5.4 Condenser Fan Blade

The condenser fan blade pulls air through the condenser. If the blade is damaged or

is not positioned correctly in the condenser shroud, the blade will not pull or push

the correct amount of air to cool the condenser coil, reducing refrigeration effi-

ciency.

5.5 System Leak

Symptoms of a refrigerant leak include a running compressor with a hot suction

line and the compressor running excessively hot, and an increased amp draw by

the compressor. A sweep of the refrigeration system is necessary to determine if

there is a leak.

If there is a leak in the system, it must be evacuated and repaired by an certified

refrigeration technician. The system must then be pulled down to a vacuum and

recharged with the correct level of refrigerant.
