Troubleshooting Tips
Save time and money! Review the chart below first and you may not need to call for service.
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.
The fuse is blown/circuit
breaker is tripped. 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.
