How Can I Tell My Thermostat Is Broken?

Imagine you’re shivering in the middle of the night, wondering what’s going on with your HVAC system. It can be a stressful experience—especially when temperatures start to dip and with no alternatives to stay warm. Most of the time, your thermostat is the one to look at, but how can you tell if it’s broken?

This blog post will share with you the common signs to identify a broken thermostat, so you can be sure to call an HVAC contractor to fix it. 

Read on to find out 5 signs of a faulty thermostat, even in the middle of the night!

5 Signs Of A Damaged Thermostat

Dealing with a damaged thermostat can be daunting, especially since the first thing you need to address is the cause of the problem. To help you identify a faulty thermostat, here are 5 common signs:

The Thermostat Has No Power

If your thermostat screen is black, that’s a sure sign that something is wrong. Usually, the display should show the room temperature and information about your programmed settings. A loose wire or a bad connection can be the cause, leaving you at the mercy of the elements.

The Temperature Is Not Accurate

Much like a broken thermometer, if your thermostat is off by more than a few degrees, it’s no longer accurate and needs to be looked at. All the settings in the world won’t make up for an incorrect temperature reading.


The HVAC System Won’t Turn On/Off

If you can’t get your HVAC system to turn on/off, the issue may be with the thermostat. A bad connection or a miscommunication from the central unit could be causing it not to respond correctly.

Short Cycling

When your home’s HVAC system short-cycles, its heating/cooling cycles often run but stop short of reaching the thermostat’s set temperature. This behavior indicates a malfunctioning thermostat. This malfunction can be caused by the thermostat’s sensor not registering the temperature correctly or sending faulty signals to the unit.

The Thermostat Ignores Programmed Settings

Your thermostat’s computer brain isn’t registering your settings. Even if you set the thermostat to a specific temperature, it won’t obey. This is a sign that your thermostat needs to be looked at by an expert.
