Malfunctioning Air Conditioners

Summers in Bloomington, IL are sizzling-hot and humid. The last thing you’ll want to deal with is a malfunctioning control module on your air conditioner. The control module regulates the system’s functions, including cycle length, timing, and speed. Read on to learn the signs of a malfunctioning control module in your cooling system.

Inconsistent Cooling

When your air conditioner has a malfunctioning control module, you may notice inconsistent cooling. Your home might not reach the temperature you’ve set on the thermostat. The system may reach the right temperature in the morning, but it may struggle to cool your home as the outdoor temperature rises throughout the day.

Irregular Cycle Duration Time

If your air conditioner is oversized, it will cycle frequently. All the starting and stopping wears out the control module, explains the Department of Energy. In addition to frequent cycling, another sign of impending control module failure is irregular cycle duration. If the system short-cycles or won’t turn off after 10 minutes, a malfunctioning control model could be the cause.

Uneven Air Distribution

When control modules fail, they may cause the cooling system to have issues with air distribution. Some areas of your home may be warmer than others. You may notice some vents don’t blow any air. This is most common with zoned cooling systems, but it can happen in any system.

Unresponsive Air Conditioner

If your air conditioner won’t respond, the first likely cause is a tripped breaker. After that, check the thermostat to ensure that it’s set to cool. If your cooling system still won’t respond, a malfunctioning control module could be the problem. The module might not be receiving the signal from the thermostat. It needs this signal in order to initiate a cooling cycle.
