How to Tell If Home Thermostat Has Gone Bad

Your thermostat has a big job to do. Without it, your air conditioning system wouldn’t know when to cool or heat your home. But what do you do when you think your thermostat is broken or might be on its way out? If only there were some easy way to tell if your thermostat was bad before shelling out the cash to replace it. Ah, but there is! If you think your thermostat might be on its last leg, follow our seven-step guide to find out.

Instructions

Step 1. Set your thermostat five degrees higher or lower than the setting you normally have it on. This will depend on whatever season it currently is (i.e., higher for the winter, lower for the summer). Check the thermostat to see if it turns on.

Step 2. Check your thermostat to ensure there is not a simple problem causing an issue. Make sure that the thermostat is on the correct “HEAT” or “COOL” setting and that the air conditioning setting is in the “ON” position.

Step 3. If Steps 1 and 2 didn’t undercover any issues, check the wiring. Turn off the power for your furnace and air conditioning system at the breaker. Remove the cover to your thermostat, which should come off by hand. Check that the wires are firmly attached to their respective mountain screws. Reattach any loose wires or screws if necessary.

Step 4. Turn the breaker back on and determine whether your thermostat runs by completing Step 1 again. If it doesn’t work, turn off the power at the breaker panel again.

Step 5. Again, look at the wires within the thermostat. If you are having difficulties with your air conditioning system turning on, look for the red and green wires; furnace issues look for red and white.

Step 6. Unscrew the two wires (either red and green or red and white) from their terminals. Be sure to grip the wires tightly, so they don’t fall behind the wall.

Step 7. Wrap the two wires together and turn the power back on at the breaker. If your air conditioner’s blower turns on, your thermostat is likely bad, and you will need to replace it.
