What to do if your AC Has a Sensor Problem?

Your AC sensor plays a vital role in making sure your AC system runs efficiently and reliably. This sensor, located near the evaporator coils inside the unit, measures the temperature of air passing over it. This temperature measurement is then sent to your thermostat to determine if any action is needed. For example, if the temperature rises above that set on the thermostat, your AC unit would kick on to cool things down.

As you can imagine, an improper reading by your AC’s sensor can cause some serious problems.

Indications your AC Has a Failing Thermostat Sensor

  • Frequent cycling on and off
  • Randomly turning on or off during times when it shouldn’t
  • Poorly managed room air temperature (hotter or colder than it should be)
  • Erratic cycles

DIY Thermostat Sensor Repairs

Although AC repairs are almost always best left to the professionals, there may be a couple things you can do yourself before giving us a call.

  • Turn off your AC unit and kill all power to the system using your breaker box
  • Remove the cover of your unit indoors
  • Inspect the evaporator coils
  • Look to see if the sensor has been bent away from the coils OR if it is making direct contact (it should be close but not touching)

We can quickly diagnose the problem and get your unit running properly again in no time.
