ENGLISH
Before calling for service, please review the following list of common problems and solutions. The air conditioner is operating normally when: You hear a pinging noise. This is caused by water being picked up by the fan on rainy days or in highly humid conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency. You hear the thermostat click. This is caused by the compressor cycle starting and stopping. You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid conditions or on rainy days. This water overflows and drips from the rear of the unit. You hear the fan running while the compressor is silent. This is a normal operational feature.
Owner's Manual 29
Troubleshooting
The air conditioner may be operating abnormally when:
Problem Possible Causes I The air conditioner is unplugged. I The fuse is blown/circuit breaker is tripped. Air conditioner does not start I Power failure. 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 2 weeks. See the care and Maintenance 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 High Fan or High Cool with thermostat at 1 or 2.
I Airflow is restricted.
I The thermostat may not be set high enough. I The air filter is dirty.
I The room may have been hot. I Cold air is escaping. I Cooling coils have iced up.
I Ice blocks the air flow and stops the air conditioner from cooling the room.
