Is Your AC Acting Erratic? It Could Be a Faulty Control Board

Is Your AC Acting Erratic? It Could Be a Faulty Control Board

Florida’s hot and humid climate relies on a well-functioning air conditioner (AC) to keep your home cool and comfortable. But what happens when your AC starts behaving strangely, or even refuses to turn on altogether? The culprit could be a faulty control board, the brain of your AC system.

What is a Control Board, and What Does It Do?

The control board, also known as the circuit board, is the central computer of your AC system. Located inside the indoor unit, it’s a complex circuit board containing microprocessors and electrical components. The control board receives signals from your thermostat and relays instructions to various AC components, including the compressor, condenser fan, evaporator coil, and blower fan. It essentially manages the entire cooling process to ensure your AC operates efficiently and maintains your desired temperature.

Signs of a Bad Control Board

A faulty control board can manifest in several ways:

  • Inconsistent cooling: The AC might struggle to maintain a consistent temperature, cycling on and off frequently or not cooling effectively.
  • Inaccurate thermostat readings: The thermostat might display incorrect room temperatures, causing the AC to malfunction.
  • Strange noises: The AC unit might emit unusual noises, such as clicking, buzzing, or humming sounds, even when not running.
  • Complete failure: In the worst-case scenario, the control board might fail entirely, preventing the AC from turning on at all.
