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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It picks up on your temperature preferences and makes an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your house or out and about and can raise and lower settings to help you save even more.

The Nest is compatible with a full range of 24-volt heating and cooling systems, but it’s always a wise idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy provider 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 install it on your own or hire a HVAC specialist like Solar Air Inc. . If you’re putting it in without help, you’ll spot a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your residence or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t a problem as the thermostat can get ample power from other heating and cooling wires.

Sometimes, your heating and cooling system may require that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is better than outdated programmable thermostats that use a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and turn on your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t draw enough power, Nest says you could run into some of these problems:

  1. Short battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t stop running.
  5. Your system is making weird noises, such as chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or frequently turning on and off in a short period of time.
  7. There is a delay notice on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t run or turns off and on frequently in a short period of time.

You may believe something is wrong with your heating and cooling system, but if you just got the Nest, we recommend you check your thermostat initially. This is especially true if the weather is moderate, and you haven’t been using your heat or air conditioning much.
