Common Reasons Why Your Window AC Compressor is Not Turning Off & Solutions
When your window air conditioning (AC) unit behaves erratically and the compressor doesn’t turn off, it can be due to several factors. Identifying and addressing these issues promptly can save energy, prevent further damage, and maintain a comfortable indoor environment.
Consider the thermostat of your AC unit as the ‘traffic cop’. It commands the compressor when to start (cooling the room) and when to stop (once the desired temperature is achieved). But what if this cop starts giving flawed signals, or worse, all green lights?
Identifying a Faulty Thermostat
A faulty thermostat might send incorrect signals to your AC’s compressor, causing it to run continuously, even when the room has reached or even dropped below the set temperature. It is akin to having a faulty speedometer in your car, where you’re unaware of when to speed up or slow down.
How to Repair a Faulty Thermostat
Addressing this issue is not as daunting as it might initially appear. Fixing a faulty thermostat can range from making minor adjustments, such as recalibration, to replacing it altogether.
To do this, first consult your AC unit’s user manual, which should provide a step-by-step guide. However, if the issue persists or you’re uncertain about the repair process, it is highly recommended to enlist a professional HVAC technician’s help.
Malfunctioning Relay Switch
Another potential offender when your AC compressor won’t rest could be the relay switch. This component serves as a link, conveying the thermostat’s instructions to the compressor.
Symptoms of a Malfunctioning Relay Switch
If your AC unit runs continuously, the relay switch may be stuck in the ‘on’ position. It’s much like having a door that’s jammed open and won’t close no matter how hard you try. This not only wastes energy but can also overwork the compressor, potentially leading to more serious issues.
Replacing a Relay Switch
The solution to a stuck relay switch usually involves replacing the component. Although this sounds straightforward, the exact steps vary depending on your specific AC unit’s model and design. Therefore, unless you’re confident and experienced in handling HVAC equipment, it would be prudent to leave this task to a trained professional.
Problems with the Control Board
Lastly, your AC’s control board could be the reason behind the relentless running of your compressor. Acting like the system’s brain, it ensures smooth coordination of all the components.
Signs of Control Board Issues
Control board problems often present as erratic behavior from your AC unit. For example, you may notice random changes in your unit’s settings. This is comparable to a chess player who suddenly starts making unpredictable, irrational moves.
Resolving Control Board Problems
Resolving control board issues can be challenging, given their complex nature and the intricate circuits involved. However, one simple step you can try before calling a professional is resetting your AC unit, akin to rebooting a computer when it’s not performing as expected. If a reset doesn’t resolve the problem, a professional technician may need to repair or replace the control board.
