Air Conditioner Control Board: What It Is and When to Replace It

What is an AC control board?

The control board is the brain of your air conditioner. It manages signals from the remote, regulates the compressor, fans, temperature sensors, and more. Without it, your AC system can't function properly.

Main signs of a faulty control board

  • AC won’t turn on or doesn’t respond to the remote
  • Flashing indicators or error codes on display
  • Irregular operation of indoor or outdoor units
  • Random shutdowns or startups

Repair or replacement: what’s better?

While some boards can be repaired, complete replacement is often more reliable — especially when chips are burned or there are overheating traces.

Compatible with top air conditioner brands

At Only-Spares, we offer new and compatible control boards for Tosot, Gree, Haier, Cooper&Hunter, Olmo, TCL, Daikin, Midea, Mitsubishi, Samsung. Select by model for easy and accurate installation.
