Troubleshooting
Before you call for service ...
If you are having an operating problem, check
the chart to see what the cause might be before
you call for assistance.
PROBLEM CHECK IF WHAT TO DO
Unit won’t run. • Power cord is plugged into a live
circuit with proper voltage.
• Fuse has blown or circuit breaker has
tripped. Also, check if a time-delay
fuse has been used.
• System Control is set to OFF.
• Local power has failed.
• Firmly plug power cord into
electrical outlet. Check circuit
voltage at fuse/circuit breaker box.
• Replace fuse with a time-delay
fuse of the correct capacity. Reset
circuit breaker.
• Set System Control to another
setting.
• Wait for power to be restored.
Unit blows fuses
or trips circuit
breaker. • Time-delay fuse being used is of
correct capacity.
• An extension cord is being used.
• Cooling circuit was turned off and on
again quickly.
• Replace fuse with a time-delay
fuse of the correct capacity.
• Do not use an extension cord
with this or any other appliance.
• Wait at least 3 minutes after
turning cooling circuit off before
trying to restart unit.
Unit turns on and
off, or does not
cool room.
• Filter is dirty.
• Inside evaporator coils and
outside condenser coils are dirty.
• There is excessive heat or moisture
in room.
• Fan speed is too low.
• Thermostat setting is too low.
• Clean filter. (See page 5.)
• Clean coils. (See page 6.)
• Use exhaust fans to reduce
room heat, or set Exhaust
Control to CLOSED to reduce
moisture.
• Set System Control to a higher
setting.
• Set Thermostat Control to a
higher number.
Normal operating sounds...
When your room air conditioner is operating
normally, you will hear sounds such as:
• Droplets of water hitting the condenser, causing
a “pinging" or “clicking" sound. Water droplets
help to cool the condenser.
• Air movement from the fan, especially on HI
COOL setting.
• “Clicks" from the cooling cycle.
Sounds also may be caused by house construc­
tion - such as vibration of the unit due to wall
construction or unsteady window mounting area.
