Thermostat not working

Do you ever get that issue that your HVAC thermostat is not working properly? Sometimes, we must make a beeline for our thermostat because the indoor temperature does not match our thermostat reading. Whether it’s a chilly night or a brutal summer day, thermostat problems can be frustrating and alarming.

Some people tend to replace their HVAC system if the thermostat is not working. But you should remember that all thermostat problems do not result from a failing HVAC unit or broken furnace. You might feel alone and frustrated when your thermostat is out to get you. But don’t worry; we’re here to save you!

In this write-up, our experts will share why your thermostat is not working and when to call a professional.

Reasons Why Your Thermostat is Not Working

It is vital to catch the early indicators of your thermostat problems; otherwise, they can result in costlier repairs. The following reason will help you identify your thermostat issue and fix it as soon as possible.

  • Outdated Thermostat

Electronic equipment doesn’t last forever, not even your thermostat. If your unit is over 10 years old, it may be the right time to replace it. An outdated thermostat can affect your HVAC system’s overall performance and efficiency, resulting in higher energy bills. You need to invest in smart and programmable thermostats that are easier and simple to integrate with your existing HVAC system.

  • Loose Thermostat Connections

Loose terminal screws and wires inside the thermostat can also be the reason your system is not working properly. Check for loose connections and ensure that wires and screws are not corroded.

If your thermostat’s heating, cooling, and fan connection is detached or corroded, your thermostat may not be able to communicate appropriately with your HVAC system. Secure loose wires, tighten terminal screws and avoid removing the thermostat cover without turning off the power.

  • Dirty Thermostat

Your thermostat will only function if you ensure its regular maintenance and cleanliness. Spider webs, dust, and dirt can coat the thermostat and disturb its electrical connection with your HVAC unit. You can gently clean the inside components of your thermostat using a soft brush.

  • Poor Airflow

Any problem with the airflow can also stop your thermostat from working properly. An airflow problem can cause AC or furnaces to freeze or overheat, resulting in thermostat malfunction.

  • Power Failure

The thermostat’s power failure is the main reason why your thermostat is not working. If the screen of your thermostat is dark, it means that no power is getting into your system. Before panicking, check for tripped circuit breaker, blown fuse, and dead batteries.
