Problem
The Air Conditioner Will Not Start
Possible Cause
- The air conditioner is unplugged.
- The fuse is blown/circuit breaker is tripped.
- Power failure
- The power cord reset button is tripped.
Recommended Solution
- Make sure the power supply cord is plugged into a grounded 3 prong outlet.
- Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
- The unit will automatically restart when power is restored. There is a protective time delay (approximately 3 minutes) to prevent tripping of the compressor overload. The unit may not start normal cooling for 3 minutes after it is turned back on.
- Press the reset button located on the power cord plug. If the reset button will not stay engaged, discontinue use of the air conditioner and contact a qualified service technician.
Problem
The Air Conditioner Is Not Cooling Properly
Possible Cause
- Airflow is restricted
- The temperature control is not set correctly.
- The air filter is dirty.
- The room is too warm.
- Cold air is escaping.
- The cooling coils are frozen.
Recommended Solution
- Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.
- Lower the set thermostat temperature.
- Clean the filter. See the “Air Conditioner Care” section.
- Allow time for the room to cool down after turning on the air conditioner.
- Close all open doors and/or windows where warm air may be entering.
- See “The Air Conditioner Is Freezing Up” below.
Problem
- The Air Conditioner Is Freezing Up
Possible Cause
- Ice is blocking the airflow.
Recommended Solutions
- Turn off the unit and allow it to thaw until the ice has melted, then operate on a higher fan speed. If this continues to occur, contact customer service for additional help.
Problem
- The Remote Control Is Not Working
Possible Cause
- Batteries are inserted incorrectly
- Batteries are dead.
Recommended Solutions
- Check that the batteries are inserted in the correct direction.
- Replace the batteries and dispose of them in a responsible manner.
Problem
- Water Is Dripping From the Unit on the Outdoor Side
Possible Cause
- The weather is hot and humid.
Recommended Solutions
- This is normal during periods of high humidity. NOTE: Do not drill a hole into the bottom of the metal base pan; doing so will reduce cooling performance.
Problem
- Water Is Dripping Inside the Room
Possible Cause
- The air conditioner is not properly leveled.
Recommended Solutions
- The air conditioner should slope slightly downward toward the outside. Level the air conditioner to provide a downward slope toward the outside to ensure proper drainage. See the “Installation Instructions” section. NOTE: Do not drill a hole into the bottom of the metal base pan; doing so will reduce cooling performance.
Problem
- Water Collects in the Base Pan
Possible Cause
- Moisture removed from the air is collecting in the base pan.
Recommended Solutions
- This is normal. Water that collects in the base pan will evaporate to the outside air. This helps with the unit’s cooling process.
NOTE: Do not drill a hole into the bottom of the metal base pan; doing so will reduce cooling performance.
