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 on the market today. And for good reason. It picks up on your temperature preferences and creates an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your house or out and about and can change temperatures 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 good idea to check the Nest thermostat compatibility checker before getting one. Don’t forget to talk with your energy company for valuable rebates, because you might be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either install it yourself or hire a HVAC pro like Ocean Air Conditioning and Heating . If you’re wiring it without help, you’ll notice a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your residence 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 draw adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is an improvement from aging programmable thermostats that rely on a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and run your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t receive adequate electricity, Nest says you could run into some of these problems:

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t shut off.
  5. Your system is making odd noises, like chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or repeatedly turning on and off in a short period of time.
  7. There is a delay notification on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t switch on or turns off and on rapidly in a short period of time.

You might think something is up with your heating and cooling system, but if you just got the Nest, it’s best to start with your thermostat first. This is especially timely if the weather is mild, and you haven’t been using your heat or air conditioning much.
