What to Do if the Thermostat Is Not Working?

A well-functioning air conditioning system is essential for home comfort, especially during hot summer days. Any changes in the air conditioner performance are stressful, including thermostat malfunctions. However, before calling your HVAC technician, do some checking first.

Minor thermostat problems can mimic more issues with the HVAC system impacting its overall capacity. You must be wondering about dramatic events with flying sparks or smoke alarm detectors’ blaring sounds, but this rarely happens. Most of the problems arising in the system’s thermostat cause almost sudden changes in the air conditioning unit’s cooling performance. And since the system’s functionality is affected, the issue can be easily confused as an HVAC emergency repair when simple troubleshooting can solve your problems away.

This article covers up simple troubleshooting solutions that will help you determine the problems with your thermostat. Let’s dip right in, shall we?

1. Check for power

The checking of the thermostat power should be the very first thing you need to do. This task is simple, check whether the wiring of your thermostat is correctly and tightly fit.

2. Examine for any dust or dirt particles

A dirty wire can be the leading cause why your thermostat is not working. Dirt affects the thermostat’s calibration causing it to interfere with its functionality, and it can increase your bill by up to approximately 7%.

Thermostats can be cleaned by first removing the cover. Second, for you to gently clean the dirt particles, take a soft-bristled brush. Note to be careful not to touch any interior parts with your fingers. After your thermostat is clean, it is a great idea to replace the batteries before putting the cover back on.

3. Look for any corroded and loose wires.

Your air conditioning system’s thermostat is attached to wiring that runs through the panel box. Over time of use, wires can become loose, faulty, and detached. So, tighten up any loose wires and replace corroded ones. See if the interruption in your thermostat connection has stopped.

4. The thermostat should be balanced and leveled.

Make sure that the thermostat is not tilted or slanted by any means – this might be just a minor detail, but your thermostat needs to be leveled and balanced for it to function in its optimum capacity. Take note that your thermostat should be mounted at least 5 feet from the ground.

5. Check for the correct 'heat' and 'cool' setting.

Check the thermostat’s setting to make sure that the switches for your cooling and heating system set to “on” mode.

If either your furnace or air conditioner is blowing air every time, the setting in your thermostat’s fan might be on, where it should be ‘auto’ which means that the blower will only blow air out of the vents.
