How to Tell If You Need a New Thermostat

Signs You Need a New Thermostat

How often do you think about your thermostat?

This small device usually goes ignored somewhere on a wall in a hallway. Family members may switch temperatures now and then, but for the most part, it’s rarely on your mind.

However, once your home starts feeling too cold, too warm, or the AC doesn’t turn on, that’s all you can think about.

5 Signs You Need a New Thermostat

There are instances when you need a new thermostat; but other times, an issue can be resolved by changing batteries or even changing its location (yes, that’s a real thing). So how do you know what would be the best solution for your home?

Learn the signs that you may need to replace your thermostat.

1. Temperature Reading Is Incorrect

If you’ve set your thermostat to, say, 72 degrees, and your home feels much cooler than that, but the thermostat shows a higher temperature, the issue may be the location of the thermostat.

If it’s installed anywhere near a room where the temperature fluctuates regularly (such as the kitchen, a laundry room, or anywhere that’s in constant direct Florida sunlight), it’s possible for the rest of your home to have reached your desired temperature, but the thermostat is reading a warmer environment due to a baking oven or a running dryer.

Switching its location to an interior wall of the room you spend the most time in will ensure that you get an accurate temperature reading.

2. Thermostat Screen Is Blank

A blank thermostat screen could be the result of several factors: A tripped circuit breaker (this could likely be the case if you’ve been running too many appliances at once or your home recently experienced a power surge), a blown fuse, dusty wires, or dead batteries.

Check the breaker panel for a switch that’s labeled “air conditioner/AC”. If it has tripped to the “off” setting, make sure to set it to the middle neutral setting before turning it back to “on”.

If the breaker is already set to “on” and the screen is still blank, use a multimeter to see if you have a blown fuse. If the fuses are working fine, take off the thermostat cover and clean the wires with a can of compressed air. If none of the suggestions above resolve the issue, replace the thermostat batteries.

3. AC Doesn’t Shut Off

Before you blame the thermostat, look at your air conditioning system as a whole: Are the air filters clean? Are all the vents open? Is the condensate line clogged? Do you have a refrigerant leak? All of these issues could be prevented by having regular HVAC maintenance checks. If all of these components are running smoothly, then you can address a faulty thermostat.

4. AC Cycles off Too Fast

A likely culprit for this issue is an oversized air conditioner. However, this is only the issue if the rooms that are furthest away from the thermostat heat up at a much faster rate than the rest of the rooms and you can see condensation forming on your windows.

5. AC Won’t Turn On

If you recently replaced your thermostat and now the AC is not turning on, it’s possible that the device is mismatched to your AC system. If you haven’t replaced any parts, you might have a wiring issue (which should only be attended to by an electrician). Also keep in mind that the average lifespan of an air conditioner is 15 to 20 years. If yours is around that age, it may be time to replace the entire system.

If you’ve tried all of the troubleshooting options listed above and none of them have corrected, it’s time to replace your thermostat.
