Many times a window model can be brought back to full function by following some simple troubleshooting techniques. By following these tips, the homeowner just might avoid an unnecessary and expensive service call.
Here’s what to do when a window unit air conditioner keeps shutting off.
First, when the thermostat seems to be at the proper setting and the unit keeps turning off, look at the electrical power source. Condensers often get unplugged just by accident. Make sure electrical plugs are actually plugged in. Also, if the breaker which controls the unit keeps tripping, it may be something as simple as a power surge. Check all the breakers, including the one on the A/C circuit.
Second, make sure that the thermostat on the unit is at the right temperature. Also, look at the heat switch to be sure that it is off. A simple mistake like this could be causing the air conditioning unit to shut off.
Of course, these troubleshooting tips are very simple. It’s important that the average homeowner not try major repairs or poke around with electricity.
Leave this to the professionals who understand the ins and outs of electrical equipment. Avoid shock hazard, and do not void the air conditioner’s warranty with a botched repair attempt. Always call a trained and experienced HVAC technician for more complicated issues with the unit.
It’s good practice to be as familiar as possible with how a window air conditioner functions. Read the owner’s manual, and perform all routine maintenance. Beyond this, when a window unit keeps shutting off, call in a technician.
