• AC Unit Fails to Start: If your AC unit doesn’t turn on at all, the circuit board could be the culprit. This could be due to a blown fuse, a power supply issue, or a complete failure of the board.
• AC Unit Runs Intermittently: The AC unit may start and stop randomly, even if the thermostat is set to cool. This could indicate a problem with the circuit board’s ability to control the components.
• Fan Motor Doesn’t Run: If the indoor or outdoor fan motor fails to operate, the circuit board may not be sending the necessary power or control signals.
• Compressor Doesn’t Run: The compressor is the heart of the AC unit, and if it fails to start, the circuit board could be at fault. This could be due to a relay failure or other control issues.
• Unusual Noises: Strange noises, such as clicking or buzzing sounds, may indicate a problem with the circuit board’s relays or other components.
• Erratic Cooling Performance: The AC unit may not cool the space effectively, or the cooling may be inconsistent. This could be due to the circuit board’s inability to properly control the compressor and fan motors.
• Blown Fuses: Repeatedly blown fuses are a strong indicator of a circuit board problem. The board may be drawing too much current or causing a short circuit.
• Burn Marks or Visible Damage: Visually inspecting the circuit board for burn marks, melted components, or other damage is a good first step in diagnosing the problem.
