Thermostat Giving You Trouble? Know How To Troubleshoot It

Do you think that something is wrong with your home's HVAC system? While you may assume the problem is with your air conditioner or your furnace, the problem may actually be due to your thermostat. Thankfully, it's possible to troubleshoot this important part of your HVAC system to determine if the thermostat is the cause of your problems.

Check The Batteries And Fuse

The first thing you should check is the thermostat batteries. It's possible that the batteries are low and there is simply no indicator on the display to let you know that it's time to replace the batteries. It's also possible that the thermostat is getting power and that the display is turned on, but the unit is not properly functioning. This is why you want to swap out those old batteries for new ones to see if that does the trick and gets the HVAC system working again.

Your thermostat may have a fuse inside it that has blown. You'll want to open up the fuse compartment to access and remove the fuse, take it to your local hardware store, and purchase a replacement fuse. Pop it back in the thermostat and everything should be running once again.

Try Alternating Systems

If your air conditioner and furnace are using the same thermostat, try alternating between both systems to make sure that they are both working. If the air conditioner is not working, but the furnace turns on, it can help narrow down the problem to the wiring of one part of your HVAC system.

Verify The Internet Connection

Did you recently make changes to your home network, such as getting a new router, assigning a new network name, or changing the network password? If you have a smart thermostat, you'll want to verify that the device is still connected to your network. This could be why you can no longer control the thermostat with your smartphone app, or why the thermostat is giving you an error that started suddenly.

Try A New Thermostat

One way to completely eliminate that the problem is with the thermostat is to swap it out with a new one. If you have an expensive thermostat, it doesn't have to be replaced with a new one that is equally expensive. You can test it by temporarily installing a bare-bones non-programmable thermostat that offers very basic controls. If the new thermostat works correctly and the old one does not, then you can narrow down the problem to your old thermostat.
