Why Your Nest Thermostat Isn't Working and How to Solve the Problem

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats you can get. And for good reason. It figures out your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or gone and can raise and lower temps to help you save even more.

The Nest is compatible with a vast range of 24-volt heating and cooling systems, but it’s always a good idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy company for valuable rebates, as you might be able to get a Nest for free or close to it.

Once you’ve made sure it’s compatible, you can either wire it yourself or contact a HVAC professional like Bain Heating & Air Conditioning, Inc. If you’re wiring it on your own, you’ll see 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. Most of the time, Nest says this isn’t an issue because the thermostat can draw adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is an improvement from older programmable thermostats that rely on 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 receive ample electricity, Nest says you may experience some of these problems:

  1. Poor battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is creating weird noises, including 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 message on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly working, won’t switch on or turns off and on rapidly in a short period of time.

You may believe something is suspect with your heating and cooling system, but if you just installed the Nest, we advise you begin with your thermostat right away. This is especially timely if the weather is mild, and you haven’t been running your heat or air conditioning much.
