Possible Cause
The unit is unplugged.
The fuse is blown/circuit breaker
is tripped.
Power Failure.
The current interrupter device is
tripped.
Indoor airflow is restricted.
The temp control may not be set
properly.
The air filter is dirty.
The room may have been hot.
Cold air is escaping.
Cooling coils have iced up.
Ice blocks the air flow and stops
the air conditioner from cooling
the room.
Hot, humid weather.
The air conditioner is not tilted to
the outside.
Moisture removed from air and
drain into base pan.
What To Do
Make sure the air conditioner plug is pushed completely
into the outlet.
Check the house fuse/circuit breaker box and replace
the fuse or reset the breaker.
The unit will automatically restart in the setting last
used after the power is restored.
There is a protective time delay (approximately
3 minutes) to prevent tripping of the compressor
overload. For this reason, the unit may not start normal
cooling for 3 minutes after it is turned back on.
Press RESET button located on the power cord plug.
If the RESET button will not stay engaged, discontinue
use of the air conditioner and contact a qualified
service technician.
Make sure there are not curtains, blinds or furniture
blocking the front of the air conditioner.
Turn the temperature control to a higher number.
Clean the filter at least every 30 days. See Care and
Cleaning section.
When the air conditioner is first turned on, you need to
allow time for the room to cool down.
Check for open furnace registers and cold air returns.
See "Air conditioner freezing up" below.
On models with control knobs, set the mode control at
High Fan or High Cool with the Temp at 1 or 2.
This is normal.
For proper disposal, make sure the air conditioner
slants slightly from the case front to the rear.
This is normal for a short period in areas with little
humidity; normal for a longer period in very humid
areas.
