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 numidity 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 Air conditioner does not cool as it should Air conditioner freezing up What To Do Make sure the air conditioner plug is pushed completely into the outlet. The fuse is blown/circuit breaker is tripped. Check the house fuse/circuit breaker box and replace the fuse or reset the breaker. Power failure. If power failure occurs, turn the OPERATION control to OFF( O ) . When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload. Airflow is restricted. Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner. THERMOSTAT control set too warm. Turn the THERMOSTAT knob clockwise to a cooler setting. The air filter is dirty. Clean the filter at least every 2 weeks. See the operating instructions section. The room may have been hot. When the air conditioner is first turned on you need to allow time for the room to cool down. Cold air is escaping. Check for open furnace floor registers and cold air returns. Set the air conditioner's vent to the closed position. Cooling coils have iced up. See Air Conditioner Freezing Up below. Ice blocks the air flow and stops the air conditioner from cooling the room. Set the OPERATION control at fan ( ) or HIGH cool ( ) with the THERMOSTAT at the warmer position or the temperature at more than 23°C. -11- Installation Instructions Air conditioner does not start Possible Causes The air conditioner is unplugged.
