Maintenance and Service
What To Do
• Make sure the plug is completely
plugged into the outlet.
• Check the fuse/circuit breaker box and
replace the fuse or reset the breaker.
• In the event of a power failure, set the
power control to OFF. When the power
is restored, wait 3 minutes to restart
the air conditioner to prevent the
compressor from overloading.
• Press the 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 no curtains,
blinds, furniture or other obstacles in
front of the air conditioner.
• Set the TEMP control to a lower
number.
• Clean the filter at least every 2 weeks.
Refer to the "Maintenance and
Service" section of the manual.
• After the air conditioner is turned on,
you need to give the air conditioner
some time to cool the room.
• Check for open furnace floor resisters
and cold air returns.
• CLOSE the air conditioner vent.
• See Ice appears on the air
conditioner below
• Ice may block the air flow and obstruct
the air conditioner from properly
cooling the room.
Set the mode control at High Fan or
High Cool with the high temperature.
