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 relay 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 run even when the compressor does not.
Abnormal Operation
Problem Possible Causes s The air conditioner is unplugged.
Air conditioner does not start
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. � 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. � Set the TEMP Control to a lower number. � 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 mode control at High Fan or High Cool with the high temperature.
