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.
