Your air conditioning unit serves an integral part in your home. It makes your home cool and comfortable, helps you sleep better, and improves your work performance. If your air conditioner is not working correctly, your house will be unpleasant, and it may lower your productivity. Regular air conditioner service ensures your system will not stall unexpectedly. Air conditioners use error codes to alert you that something is not working accurately. One of these error codes is Error 8.

What Does Error 8 mean?

If you have a mini split air conditioner, an error 8 will occur when there is a fan speed malfunction. Mini-splits have an indoor air-handling unit or evaporator and an outdoor condenser or compressor. If the outdoor fan or the in-door fan slows down for too long, the air conditioner will stop and display the Error 8 code.

What causes an Error 8?

Any of the following things can cause a fan speed malfunction.

  • Dirty Indoor Air Filter

Dirty indoor air filters will restrict airflow in your air conditioner, which affects the fans. It can also clog the system; meaning that the AC cannot pull enough air to keep the room at the right temperature. Bear in mind that when your AC works too hard to cool your house, it will lose its longevity.

  • Faulty Fan Motor

If the fan motor is not working, you will have a fan speed malfunction. Your fan motor may fail if there is a voltage problem, water dripping into the windings, or the run capacitor is not working. You will also experience fan motor problems if there is a loss of lubrication in the belt drive bearings. Ensure that you have an air conditioner technician come in and fix your unit if you have a faulty motor. A technician will be able to find the cause of the problem and offer air conditioner service.

  • Wiring Problems

Incorrect installation can result in wiring problems that affect how your AC works. These issues will result in failed compressors and damaged boards. These will require replacement. Make sure that you have your air conditioning unit installed by trained and experienced technicians.

  • Bad Control Boards

Mini-Splits have two or three control boards, and these may fail and need replacement. When they stop working, you may experience an error 8.

How to reset an Error 8

To reset an error 8, turn off the air conditioner and disconnect the breaker. Wait for 3 minutes and switch it on again. If you do this and the error code shows up, you will need to troubleshoot the unit further to find the problem.

Troubleshooting a Mini Split system

To troubleshoot your air conditioning unit check the fan blowers and air filters. If air filters are dirty, that might be the reason you are having the problem. Inspect the fan motor and test it. You should also check the unit’s PCB board.
