4 Signs of a Bad AC Sensor in Williamsburg, VA

Your home’s AC unit has a sensor whose role is to measure the temperature circulating through your evaporator. If you hail from Williamsburg, VA, you understand how important it is to have a functional air conditioner. A bad sensor is one of several issues that can cause your air conditioner to malfunction.

1. Faulty Thermostat

A faulty thermostat is one of the major reasons why your AC sensor may fail to work properly. This is often due to an accumulation of grime inside it or just because the lifespan of your thermostat has lapsed. It may also be due to poor installation resulting from loose wires.

2. Displaced Sensor

A sensor that’s not working properly may simply be in the wrong position. If the sensor isn’t positioned correctly, it may not be able to accurately measure the temperature of the air passing through it. You may need to seek the services of a professional to troubleshoot the sensor and restore the normal functioning of your AC unit.

3. AC Unit Not Turning Off

If you notice your AC isn’t turning off even after the house reaches the set temperature, then it means you have a faulty sensor. The air conditioner will continue blowing cold air, and the temperature may become very cold and uncomfortable. Failing to address the issue may lead to higher monthly bills due to extra energy usage.

4. AC Unit Cycling Continuously

In case your air conditioner cycles on and off continuously rather than turning off, it means you have a faulty sensor. Your unit will keep on turning on and off at random intervals until you fix the problem.

Having a bad sensor means your air conditioner won’t function efficiently. Lighthouse Mechanical specializes in HVAC repair and maintenance, so contact us today for these and other services!
