Normal Operating Sounds

Possible Causes
The air conditioner
is unplugged.
The fuse is blown/circuit
breaker is tripped.
Power failure.
Airflow is restricted.
The temp control may
not be set high enough.
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.
You may hear a pinging noise caused by
water being picked up and thrown
against the condenser on rainy days or
when the humidity is high. This design
feature helps remove moisture and
improve efficiency.
You may hear the thermostat click when
the compressor cycles on and off.
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.
• If power failure occurs, turn the mode control to OFF.
When power is restored, wait 3 minutes to restart the
air conditioner to prevent tripping of the compressor
overload.
• Make sure there are no curtains, blinds or furniture
blocking the front of the air conditioner.
• Turn the knob to a higher number. The highest
setting provides maximum cooling.
• Clean the filter at least every 30 days. See the Care and
cleaning of the air conditioner section.
• When the air conditioner is first turned on you need
to allow time for the room to cool down.
• Check for open furnace floor registers and cold
air returns.
• See "Air conditioner freezing up" below.
• Set the mode control at FAN or HIGH COOL with the
temp at 1 or 2.
Water will collect in the base pan
during high humidity or on rainy days.
The water may overflow and drip from
the outdoor side of the unit.
The fan may run even when the
compressor is not.
