Replacement Air Conditioner and Heat Pump PCB Boards NZ: Buyer's Guide

Looking for replacement air conditioner and heat pump PCB boards in NZ? We stock replacement controller boards for air conditioners and heat pumps, with delivery across New Zealand. The PCB (printed circuit board) is the control centre of your unit. It receives commands from the remote or wall controller, reads the temperature sensors and runs the fans, compressor and other components. When a board fails, the unit can stop responding, show error codes or shut down, even though the rest of the system is fine.

How to find the right PCB board for your heat pump or air conditioner

The most reliable way to match a board is by your unit's model number, so look at the rating label on the indoor unit and the outdoor unit. The indoor label is often on the side of the unit or behind the front panel. The outdoor label is usually on a side panel. Indoor and outdoor units have separate boards, so make sure you know which one is faulty. The old board often has a part number printed on it, which is a useful second check. Compare both numbers against the compatible models listed on each product page.

Fitting tips

  • Isolate the power at the switchboard before opening any panel, and wait several minutes so stored charge can drain from the board.
  • Take clear photos of the wiring and connector positions before you unplug anything.
  • Handle the new board by its edges and avoid touching the components, since static can damage it.
  • Check that the replacement matches your model or part number before fitting it, as boards that look alike can be wired differently.
  • Boards work on mains electricity, so we recommend a licensed electrician or qualified heat pump technician if you are not experienced with this work.

Frequently asked questions

How do I find the right PCB board for my heat pump?

Find the model number on the rating label of the indoor or outdoor unit, depending on which board is faulty. Match it against the compatible models on the product page, and check the part number printed on your old board if you can.

How do I know if my air conditioner PCB board has failed?

Common signs include no response to the remote, error codes or flashing lights, and fans or the compressor not starting. These symptoms can have other causes, so it is worth confirming the fault before you order.

Do I need the indoor or outdoor board?

Indoor and outdoor units have separate boards. The indoor board handles the remote, sensors and indoor fan, and the outdoor board handles the compressor and outdoor fan. Contact us with your model number and the fault if you are unsure.

Can I replace a heat pump PCB board myself?

The board itself is often a plug-in swap, but it works on mains electricity. We recommend a licensed electrician or qualified heat pump technician unless you are experienced with this kind of work.

What if my model is not listed?

Send us your unit's brand, model number and a photo of the old board if possible. We will check whether we can source the right replacement.
