A thermostat can be a lifesaver when you need cool, refreshing air on a hot day or toasty heat on a freezing one; however, there are unfortunately times when you try adjusting your thermostat and it doesn’t seem to compute your commands. This is reasonably very frustrating and, fortunately, there are some quick tips and tricks you can try should you need to troubleshoot your device.

Check the Power

A practical first step is to troubleshoot the source of power. If your thermostat’s digital display is off, check on these aspects:

  • Batteries: Most thermostats run on batteries; if this is the case for your thermostat, replace the existing batteries with fresh ones.
  • Circuit panel: Make sure the breaker hasn’t tripped.
  • Fuse: Remove the thermostat’s cover to make sure the fuse hasn’t blown. If it has, head to the hardware store to get it replaced with a matching one.
  • Wiring: Double-check that your thermostat’s wire contact hasn’t come loose. To check this, you will have to remove the thermostat from the wall. The owners’ manual can serve as a useful guide.

Mode Testing

Although this step seems like a no-brainer, make sure your thermostat is set to the mode you desire. Set it to cool for cold air and heat for warm air.

People oftentimes don’t realize their systems are set to ‘Off’ and will sit there waiting for the air to kick on. It could also be that your thermostat is set to ‘Hold’ which overrides any settings you may have programmed. Switching this off should solve the issue.

Check the Temperature Settings

Another thing that could be easily overlooked is the temperature setting. Some settings require the user to hit an ‘Enter’ or ‘Done’ button after inputting the temperature request before anything actually changes, so make sure your thermostat has received and accepted the command you’ve made.

Thermostat Calibration & Placement

Is your system working but not hitting the temperature you’ve inputted? It could be that the calibration of your thermostat is thrown off or the placement of your system is negatively impacting its performance.

Issues such as your AC running and shutting off too soon can be the result of a calibration issue. Oftentimes, this can be corrected by a professional, but your thermostat may be better off replaced altogether.

Although it’s not something that first comes to mind when your thermostat isn’t working up to par, various external factors such as a hot lamp or direct sunlight may cause your thermostat’s temperature to rise, or a cool draft from a door or window could lower the temperature.

What’s the Age of Your Thermostat?

Just like any other appliance in your home, thermostats will inevitably wear out. When the age of your system hits around 15 years, it’s likely a good time to have it replaced with a more modern and reliable one. The plus side is that, with modern technology, a replacement will ultimately be more energy-efficient, saving you money in the long run, and will be better equipped to prevent the previously discussed issues.
