Furnace Not Working: Check The Thermostat

A failing furnace can be intimidating and frustrating. It can leave you stuck in the midst of a cold winter night. However, there’s good news from HVAC pros. There are several furnace issues that can be done the DIY way.

Sometimes, the problem lies in the thermostat. Hence, before you assume that you’re having a furnace problem, take a closer look at your thermostat and do the following troubleshooting tips.

  • Make sure that the switch is set to “Heat” mode instead of “Cool.”
  • Check the temperature setting.
  • Make sure that the program is showing the right day and time, as well as morning and afternoon settings.
  • Make a comparison of the temperature setting to the room temperature. Set the temperature five degrees higher than the room temperature and check if the furnace starts on.
  • Check the furnace for breaks, especially if you have had remodeling project recently. If there’s breakage in one of the wires, fix it back together and wrap using an electrical tape.
  • Change the battery. Sometimes the easy solution is simply replacing the battery. If you have a power outage with a dead battery, then the settings will lose and will revert back to its default program.
  • Clean the thermostat. Be sure it’s balanced and firmly attached on your wall, with no lose wires coming to it.
  • If you can’t make the setting work, then you can bypass them. All you need to do is set your desired temperature with the up/down control and then punch the hold button. It should make your furnace run when the problem is your thermostat.
