Does Your Home’s Thermostat Need to Be Replaced?

Does Your Home's Thermostat Need to Be Replaced?If your HVAC system suddenly stops producing heated or cooled air, you might fear that there’s a serious issue with the A/C, heat pump or furnace. It may be that the problem isn’t with the equipment but the thermostat that controls it. You can take these steps to tell if a thermostat replacement is all that’s needed.

Adjust the Temperature Setting

Sometimes, all it takes to get a thermostat to signal the HVAC equipment is adjusting the temperature setting up or down. If you’re using the A/C, adjust the setting down by 5 degrees. If you’re using the furnace, move it up instead.

Make Sure the Thermostat is Getting Power

Head to your main electrical panel and locate the breaker that controls the thermostat. Flip it off, then reset it. If the thermostat also uses batteries and you have changed them recently, put in fresh ones.

Verify the Settings

Make sure that your thermostat’s mode switch is set correctly to “heat” or “cool” depending on the season.

Check Under the Cover

Turn off the thermostat’s breaker again, then pry off the device’s cover so you can inspect the interior. Make sure that each of the electrical wires is firmly attached to its mounting screw. If there are loose wires, reattach them. Use a soft brush to remove any accumulated dust, then clean the metal contacts with a cotton swab dipped in contact cleaner. Turn the circuit breaker back on and test the thermostat again by raising/lowering the temperature setting.

Bypass the Thermostat

If the thermostat still doesn’t respond, shut off its breaker again. Remove the unit from its mounting bracket and loosen the wires from the back. Locate the red and white wires and wrap them together. Turn the breaker back on and see if the furnace starts up. Repeat this process using the red and green wires that control the air conditioner. If your HVAC equipment starts up when the wires are wrapped together, the thermostat is bad.
