How to Troubleshoot a Haier ESA3105

Haier's model ESA3105 unit automatically performs most of its air conditioning functions, including cooling and dehumidifying the room. You can also use the remote control at a distance to change the temperature and power the A/C on and off. However, the Haier cooling unit can only go so far in the automatic comfort and amenities that it offers until the A/C malfunctions or completely stops cooling down the room. When these problems occur, you can effortlessly troubleshoot some of the most basic issues, causing only a minor and temporary inconvenience on your part.

Instructions

- 1
  Check the cord to make sure it is securely plugged into the wall outlet, if the A/C does not operate at all. Also, verify that the unit is not in the "Off" position.
- 2
  Increase the temperature setting on the A/C if the air flowing from the unit is warm and not cooling down the room.
- 3
  Verify the outdoor temperature through your local weather forecast if ice forms on the A/C's cooling coils. Cold outside air can cause these formations on the unit. Set the A/C to "Fan-Only" to keep a steady circulation of air instead of using the cooling functions. Also, consider lowering the temperature if the unit is set to an extremely cold temperature.
- 4
  Clean the A/C's air filter if the unit is operational, but failing to adequately cool the room. Close the vents on the A/C to help it to best cool the room. Check for excess heat from other room appliances, including floor-model TVs and computers. Seal and insulate windows and doors.
- 5
  Listen for a mechanical pattern if you hear and feel strange noises and vibrations from the A/C. The compressor will turn on and off with regularity. A/Cs remove humidity from the air in the surrounding room, and this conditioning process produces excess running water.
