How to Tell if Your Thermostat Needs to Be Replaced

If your home is too cold during the winter or too hot during the summer, chances are you might blame your HVAC system. However, it could be your thermostat that’s the true culprit. A thermostat failure could keep your HVAC system from working properly. The following guide can help you find out if a thermostat replacement is in your HVAC system’s future.

Check the Thermostat

First, take a look at the thermostat. If the display is blank, you’ll want to do the following:

  • Check for a tripped circuit breaker or blown fuse, as these issues can prevent your thermostat from working.
  • If the breakers or fuses are working, remove the thermostat and change its battery. A dead or failing battery can also prevent the thermostat from working.
  • Examine the thermostat for any loose or corroded wiring. If there are any loose wires, reattach them and tighten the loose mounting screws. Use a small piece of very fine sandpaper to remove corrosion from the wires and terminals.

Once you’ve confirmed that your thermostat is receiving power, the next step involves making sure the thermostat will actually turn on your furnace or air conditioner.

Test the Thermostat

If your thermostat is receiving power, you’ll want to make sure it’ll turn on your HVAC system. Make sure the thermostat is set to the “on” position and set it five degrees higher or lower than your home’s current temperature. If necessary, have a partner stationed near the HVAC system so they can hear when the furnace or air conditioner comes on. If the HVAC system doesn’t respond when the thermostat is raised or lowered, then chances are you’ll need a thermostat replacement.

Upgrading to a New Thermostat

If you need a new thermostat, now is the time to consider upgrading to a programmable thermostat. These thermostats offer a greater degree of efficiency and control, allowing you to preset temperatures according to your day-to-day needs.
