Why Your Nest Thermostat Isn't Working and How to Fix It

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats you can buy. And for good reason. It picks up on your temperature preferences and makes an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your residence or away and can change settings to help you save even more.

The Nest can be used with a wide range of 24-volt heating and cooling systems, but it’s always a wise idea to use the Nest thermostat compatibility checker before getting one. Don’t forget to contact your energy company for valuable rebates, because you might be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either wire it yourself or contact a HVAC specialist like Brookwood Inc. If you’re putting it in without help, you’ll see a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your home or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a setback as the thermostat can pull ample power from other heating and cooling wires.

In some instances, your heating and cooling system might need that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is an improvement from older programmable thermostats that use a combination of wiring and AA batteries for power. It relies on a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t draw adequate electricity, Nest says you could experience some of these problems:

  1. Bad battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is making strange noises, such as chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or constantly turning on and off in a short period of time.
  7. There is a delay notification on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly working, won’t run or turns off and on repeatedly in a short period of time.

You could believe something is up with your heating and cooling system, but if you just got the Nest, we suggest you check your thermostat initially. This is especially pertinent if the weather is mild, and you haven’t been using your heat or air conditioning much.
