H0151800054B Genuine Main Control PCB for Haier Air Conditioners, Air Conditioning Unit Control Board Replacement

H0151800054B is a genuine Haier main control PCB for Haier air conditioners. It's the board that runs the unit, so the full number including the B revision needs to match the label on the board you're replacing. Our records don't list compatible models or say whether it sits in the indoor or outdoor unit. Send your air conditioner's model and serial number through the parts enquiry form and we'll help confirm it.

Air conditioner main board failure symptoms

The main control PCB reads the remote and room sensors, then tells the fan, louvres and compressor what to do. A failed board can leave the unit completely dead, ignore the remote, flash error codes, or start and then shut down after a few minutes. Storms and power surges are frequent causes, as are moisture and insects getting into the electronics. Many faults that look like a dead board are really sensors, wiring or the outdoor unit, so a proper diagnosis by a technician saves buying the wrong part.

Who should fit an air conditioner board

Air conditioners are usually hard wired, so this board should be fitted by a licensed electrician or a licensed air conditioning technician. Isolate the unit at its isolator switch and the switchboard before any covers come off. Photograph every connector and sensor lead, and handle the board by its edges. Any work on the refrigerant side needs a refrigerant handling licence.

Questions about this part

Where do I find my Haier air conditioner's model number?

Look for the rating label on the side of the indoor unit, often under the front cover, and on the side of the outdoor unit. Send both model numbers and the serial through the parts enquiry form so we can check the board.
