Common Problems and Solutions

Troubleshooting Tips save time and money!
Review the chart below first and you may not need to call for service.

Normal Operation

• You may hear a pinging noise caused by water being picked up and thrown by the slinger fan against the
condenser on rainy days or when the humidity is high. This design feature helps remove moisture and
improve efficiency.
• You may hear the thermostat click when the compressor cycles on and off.
• Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip
from the outdoor side of the unit.
• The fan may run even when the compressor does not.

REMEDY
• Check voltage at outlet. Correct if none.
• Check voltage to rotary switch. If none, check power
supply cord. Replace cord if circuit is open.
• Check switch continuity. Refer to wiring diagram for
terminal identification. Replace switch if defective.
• Connect wire. Refer to wiring diagram for terminal
identification. Repair or replace loose terminal.
• Test capacitor.
Replace if not within ±10% of manufacturer's rating.
Replace if shorted, open, or damaged.
• Fan blade hitting shroud or cross flow fan hitting
scroll. Realign assembly.
• Units using slinger ring condenser fans must have
5
/
to
inch clearance to the base. If it is hitting the
16
base, shim up the bottom of the fan motor with
mounting screw(s).
• Check fan motor bearings; if motor shaft will not
rotate, replace the motor.
• Check voltage. See limits on this page. If not within
limits, call an electrician.
• Test capacitor.
Check bearings. Does the fan blade rotate freely?
If not, replace fan motor.
• Pay attention to any change from high speed to low
speed. If the speed does not change, replace the
motor.
