Troubleshooting Tips

Save time and money! Review the chart below first and you may not need to call for service.

Normal Operation

•  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.
•  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 continue to operate when the compressor has cycled off.

Problem

Possible Causes

What To Do 

Make sure the air conditioner plug is pushed 

completely into the outlet and switched on.

Check  the  house  fuse/circuit  breaker  box 

and replace the fuse or reset the breaker.

If power failure occurs, switch off and 

disconnect/unplug the power cord. When 

power  is  restored,  reconnect  (plug  in)  the 

power cord, switch on the power and 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.

Clean  the  filter  at  least  every  2  weeks.

 

See the operating instructions 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.

Set the air conditioner’s vent to the closed 

position.

See Air Conditioner Freezing Up below.

Set  the  fan  at  MED  or  HIGH  until    the  ice 

melts.
