Troubleshooting Tips (continued)
COMPLAINT
Unit Does Not Cool/Heat
Room Suffi ciently, Or Cycles
On And Off Too Frequently
(continued).
Unit Runs Too Much.
920-198-00
CAUSE
● The outside temperature is below
60° F (16° C).
● The digital control is set to fan
cycling mode.
● The air conditioner has insuffi cient
cooling capacity to match the heat
gain of the room.
● The air conditioner has insuffi cient
heating capacity to match the heat
loss of the room.
● This may be due to an excessive
heat load in the room.
● It may also be due to an improperly
sized unit.
● This may be normal for higher
effi ciency (EER) air conditioners.
● You may notice that the discharge
air temperature of your new air
conditioner may not seem as cold
as you may be accustomed to from
older units. This does not, however,
indicate a reduction in the cooling
capacity of the unit.
SOLUTION
● 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.
● 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.
● Check the cooling capacity of your unit to
ensure it is properly sized for the room in which
it is installed. Room air conditioners are not
designed to cool multiple rooms.
● Check the heating capacity of your unit. Air
conditioners are sized to meet the cooling load,
and heater size is then selected 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.
● 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.
● 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.
● The use of higher effi ciency components in
your new air conditioner may result in the
unit running longer than you feel it should.
This may be more apparent, if it replaced an
older, less effi cient, model. The actual energy
usage, however, will be signifi cantly less when
compared to older models.
● The energy effi ciency ratio (EER) and cooling
capacity rating (Btu/h) listed on the unit's rating
plate are both agency certifi ed.
