COMPLAINT CAUSE SOLUTION
Unit Does Not Cool/ Heat
Room Sufciently, or Cycles
On And Off Too Frequently
(continued).
Operating in Cooling mode while the
outside temperature is below 60 °F
(16 °C).
Do not try to operate your air conditioner in the cooling mode
when the outside temperature is below 60 °F (16 °C). The unit
will not cool properly, and the unit may be damaged.
The digital control is set to fan cycling
mode.
Since the fan does not circulate the room air continuously
at this setting, the room air does not mix as well and hot (or
cold) spots may result. Using the continuous fan setting is
recommended to obtain optimum comfort levels.
The air conditioner has insufcient cool-
ing capacity to match the heat gain of
the room.
Check the cooling capacity of your unit to ensure it is properly
sized for the room in which it is installed. Room air condition-
ers are not designed to cool multiple rooms.
The air conditioner has insufcient
heating capacity to match the heat loss
of the room.
Check the heating capacity of your unit. Air conditioners are
sized to meet the cooling load, and heater size is then se-
lected to meet the heating load. In extreme northern climates,
room air conditioners may not be able to be used as a primary
source of heat.
Unit Runs Too Much.
This may be due to an excessive heat
load in the room.
If there are heat producing appliances in use in the room, or if
the room is heavily occupied, the unit will need to run longer to
remove the additional heat.
It may also be due to an improperly sized
unit.
Be sure to use exhaust vent fans while cooking or bathing and,
if possible, try not to use heat producing appliances during the
hottest part of the day.
Compressor does not run.
Low voltage
Check voltage at compressor. 115V & 230V units will operate
at 10% voltage variance
Temperature not set cold enough or
room air thermistor inoperative
Set temperature to lower than ambient position. Test thermis-
tor and replace if inoperative.
Compressor hums but cuts off on over-
load
Direct test compressor.
Open overload Test overload protector & replace if inoperative
Open capacitor Test capacitor & replace if inoperative
Inoperative power button
Test for continuity in all positions. Replace User Interface if
switch inoperative.
Broken, loose or incorrect wiring
Refer to appropriate wiring diagrams to check wiring. Correct
as needed.
