Haier Air Conditioner Circuit Board & Timer Parts

Haier Air Conditioner Control Boards and Timer Parts

Your Haier AC's control board is the command center—when it fails, your unit won't respond to temperature changes, cycle on/off properly, or communicate with the thermostat. Genuine OEM Haier circuit boards and timer modules restore full system control and helps support proper fit and performance. We stock exact replacements for window units and portable models across Haier's lineup.

Common signs your board needs replacement: unit not powering on despite wall power, compressor running continuously, fan stuck on high, display showing error codes, or delayed response to thermostat adjustments. Haier Air Conditioner parts from Repair Clinic are tested and backed by manufacturer specs.

• Control Circuit Boards – unit won't turn on or respond to settings
• Timer Modules – delay-start and auto-shutoff functions not working
• Run Capacitors on Boards – compressor humming but not starting
• Relay Switches – intermittent power to fan or compressor

Haier Air Conditioner Control Board Repair Questions

What happens if my Haier AC control board fails?

A failed board means your unit loses all intelligence—no cooling cycle, no thermostat response, no timer function. The compressor may run nonstop, your fan could lock on one speed, or the entire unit stays dormant. These aren't problems you can bypass; the board must be replaced with a genuine OEM part matching your exact model.

How do I find my Haier model number for the correct circuit board?

Your model number is typically on a white sticker inside the front panel or on the side casing near the compressor. Write down the full model number (usually 12–15 characters). Haier uses different boards for window units versus portable units, so this step is critical. Enter your model in our lookup tool, and we'll display compatible boards quickly.

Can I replace a Haier control board myself?

Yes—it's a straightforward swap for most window AC models. Unplug the unit, remove the front panel or access cover, disconnect the wire harness from the old board, and plug in the new one. Portable units vary in design, so consult your manual for board location. If you're uncomfortable with electrical work, call a technician—we're here to supply the exact part.

Are Haier boards compatible with other brands like GE or LG?

No. Haier circuit boards are engineered specifically for Haier units. GE, LG, Samsung, and other brands use proprietary designs. Using the wrong board will damage your AC or can create compatibility or performance problems. Always match the part number on your failed board to ensure correct fit and function.

Haier Air Conditioner Model Number: Where to Look

Haier prints the model number on a label inside the front panel or along the side casing of most window and portable air conditioners. Unplug the unit, then check behind the front grille, inside the filter panel, and near the compressor area for a white sticker or nameplate. Record the complete model number, including any letters, numbers, or suffixes. Enter it in the model number search to pull up the parts matched to your unit. The model number filters the full Haier air conditioner parts catalog, not just circuit boards or timers, so you can narrow the results to parts made for your exact model. That means fewer wrong orders and a faster repair.
