5 Signs Your AC Thermostat is Broken

Summer’s rapid approach means Denver homeowners need to check that their air conditioning systems work right. You don’t pay much attention to your thermostat normally. But if it stops working, you have no way to control your HVAC unit.

Most wall thermostats last about 35 years and homeowners end up replacing them before they go bad. Still, it’s important to know the symptoms of a bad wall thermostat so you can get your HVAC unit running again.

Read on to learn the signs so you don’t end up stuck without control of the temperature in your Denver home.

The 5 Clear Symptoms Of A Bad Wall Thermostat

Keep an eye out for the following 5 signs so you know how to tell if your home thermostat is bad.

1. Your Air Conditioning Unit Runs All Day And All Night

Have you noticed your air conditioning running all the time even though you’ve turned it up or off? This is a clear sign of a malfunction in your thermostat.

A wiring issue or other malfunction in the signal between the wall thermostat and the HVAC system may cause this problem. You may also need to recalibrate the thermostat so that it sends the correct instructions.

2. The Air Conditioner Or Heater Refuses To Turn On

Contrarily, are you struggling with an HVAC unit that only sometimes turns on, or doesn’t turn on at all? This is another sign the thermostat is bad in your house.

Most often a wiring defect causes this issue. It could also be a malfunction in the internal instruments that measure temperature.

3. Temperatures Vary From Room To Room

Do you walk into the kitchen and freeze while sweating if you spend 5 minutes in your bedroom? When temperatures begin to vary from room to room, this is a definite sign that something is wrong.

Sometimes when the wall thermostat turns your HVAC system on and off randomly, it causes these variations in temperature. The rooms farthest away from the central AC unit do not get their fair share of air.

4. No Power To The Thermostat

The most obvious sign of a bad wall thermostat is the physical thermostat not turning on at all.

If you press buttons and it doesn’t respond, you know it doesn’t work. An unlit backlight on the display also indicates no power to the thermostat.

5. Replacing The Thermostat’s Batteries Does Nothing

Finally, you should replace the thermostat’s batteries.

If this does nothing to resolve any of the above issues, you know there’s definitely something wrong with your thermostat. There may even be issues with your HVAC system as a whole.
