Troubleshooting
- Unit does not operate immediately when restarted:
- Unit control initiates a 3-minute delay at the end of each cycle to protect the compressor from damage
- Whoosh or gurgling noise at indoor unit:
- Sometimes the refrigerant can be heard in the indoor coil when the outdoor unit starts or stops operation. This is not a malfunction.
- Mist coming out of indoor unit during cooling:
- This sometimes happens when the indoor temperature and humidity are very high and the air is being cooled quickly. The mist will disappear as the indoor temperature and humidity are lowered.
- Creaking or popping noise when unit starts or stops:
- The plastic components of the indoor units sometimes expand and contract when they are heated and cooled.
- Unit is not operating:
- Check if TIMER ON and TIMER OFF features are being used incorrectly
- Check if power is disconnected or circuit breaker has tripped
- Check if power is shut down
- System is not cooling (or heating) efficiently:
- Check if temperature setting is correct
- Check if air inlet or outlet is blocked on outdoor or indoor unit
- Check if filter is dirty
- Check if fan is at low speed
- Check if windows and doors are properly shut
- Wireless remote is not working:
- Check if remote is in direct line of sight with indoor unit infrared receiver
- Remove remote control batteries for 30 seconds, then reinsert them. Replace batteries if necessary.
- Water is leaking from indoor unit:
- Indoor humidity level is very high and water is being blown from indoor coil. This will stop as humidity level is reduced.
- Water is leaking from condensate line at indoor unit:
- Check condensate line outside to make sure it is not obstructed
- Check condensate line to make sure it has not been disconnected from indoor unit
- Water is leaking from outdoor unit:
- During operation in high-humidity areas, condensate will form on cold outdoor refrigerant pipes
- When heat pump is operating in defrost mode, ice will thaw from around outdoor coil and water will flow from the unit
- Clicking noise heard inside:
- Sometimes, the sound of the outdoor unit fan or compressor relay can be transmitted in a way that makes it seem to be coming from the indoor unit
- Indoor fan is not working:
- In HEAT mode, a timed delay keeps indoor fan off for two minutes to prevent unheated air from being circulated
- In HEAT mode, cold outdoor temperatures and high humidity cause frost to accumulate on the outdoor unit. When this happens, the unit will enter a defrost cycle and the indoor fan will be off during the 3-12 minute cycle.
- In DEHUMIDIFICATION mode, indoor fan operation may be stopped to avoid delivery of moist air to the room. Do not adjust temperature setting.
