Your AC relies on many components to keep your home cool, but one part plays a central role in keeping it all running smoothly: the control board. Often referred to as the “brains” of your AC, the control board coordinates signals between different parts of the system to ensure they operate in the right sequence. When it starts to fail, your AC can’t do its job effectively—or at all. At Peaden, our skilled Peaden Pros have the AC repair expertise to diagnose and fix control board issues for homeowners across Mobile County, AL, so you can get back to enjoying reliable comfort.
What Does the AC Control Board Do?
The control board acts like a central hub for your air conditioner’s electrical components. It receives signals from the thermostat and directs power to parts such as the blower motor, compressor, and fan. Essentially, it ensures each component starts, runs, and stops at the right time. Without a functioning control board, your AC can’t operate efficiently—or may not operate at all.
Signs Your Control Board May Be Failing
Control board problems can cause a variety of symptoms, many of which mimic other AC issues. That’s why a professional diagnosis from the Peaden Pros is so important. Watch for signs like:
- AC won’t start – If the control board can’t send the right signals, the system may fail to turn on.
- Intermittent operation – Your AC might turn off unexpectedly or fail to complete a cooling cycle.
- Unresponsive thermostat – The thermostat settings may not seem to affect the AC’s operation.
- Fan or blower issues – The indoor blower or outdoor fan may run continuously or not at all.
- Error codes on the unit – Many modern systems display fault codes that point to control board issues.
Why Control Boards Fail
In Mobile County’s hot, humid climate, AC systems work hard for months at a time, and that stress can take a toll on the control board. Common causes of failure include:
- Electrical surges – Lightning strikes or power fluctuations can damage sensitive electronics.
- Moisture exposure – High humidity can lead to corrosion and short circuits.
- Overheating – Poor airflow or other system issues can cause the control board to overheat.
- Normal wear and tear – Components naturally degrade over time, especially in older systems.
The Peaden Pros have the skills to accurately identify whether the control board is the root cause of your AC trouble—or if another part is to blame. We also use high-quality replacement parts to ensure lasting repairs.
The Cost of Delaying Repairs
A failing control board can cause other parts of your AC to run incorrectly or fail altogether. For example, a blower that won’t shut off can overheat, or a compressor that starts and stops too often can sustain permanent damage. Addressing control board issues promptly can prevent these costly secondary problems and help extend the life of your air conditioner.
If you suspect control board trouble is affecting your air conditioner, don’t wait for a complete breakdown. The control board is a complex electrical component, and replacing it isn’t a DIY project. Working with electricity requires specialized tools and training to avoid injury or further damage to the system.
