Faulty AC Sensors: A Problem You Shouldn’t Ignore

Jun 24, 2021 | air conditioning

Having an air conditioner that’s in good working condition is imperative, especially now that summer is in full swing. However, certain issues can appear out of nowhere and prevent you from enjoying a comfortable indoor space during hot weather. One of the problems that can cause your AC system to malfunction is a faulty sensor.

In this blog, residential HVAC and commercial refrigeration contractor A/C and Refrigeration explains the function of an AC sensor and how it can fail.

The Importance of the AC Sensor

The sensor is one of the most important components of your AC system. It can either be located on the thermostat or the control panel of the actual unit itself. Its primary function is to regulate and activate the desired temperature in an indoor environment. Once your room reaches the temperature indicated on your thermostat, the unit will stop blowing cool air.

Causes of a Faulty AC Sensor

There are a number of reasons why your AC’s sensor can fail. It could have been knocked out of position or be suffering from an internal issue that requires an immediate inspection from a reliable HVAC and refrigeration maintenance contractor. Remember to pay close attention to the following:

  • Thermostat issue – The faulty sensor could be due to a problem with your thermostat. This can lead to your AC turning on and off intermittently, even if your room hasn’t reached the desired temperature.
  • Displaced sensor – A displaced sensor can’t perform its function of measuring the temperature of the air moving over the coil. The AC may not work properly as a result, providing inefficient cooling for everyone in your house.

The last thing you need this summer is a malfunctioning AC system. If you notice your unit is cycling on or off frequently and your room still feels less than comfortable, don’t delay: get in touch with a reliable contractor for an inspection.
