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

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 develops 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 home or out and about and can change temps 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 talk with your energy supplier for valuable rebates, because you could be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either wire it on your own or hire a HVAC specialist like Street Heating and Cooling. If you’re wiring it 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 home or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t a setback since 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 Problems

The Google Nest Thermostat is a step up 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 link to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t get ample juice, 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 turn off.
  5. Your system is producing strange 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 notification on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly working, won’t switch on or turns off and on frequently in a short period of time.

You may worry something is suspect with your heating and cooling system, but if you just installed the Nest, we suggest you check your thermostat initially. This is especially pertinent if the weather is temperate, and you haven’t been using your heat or air conditioning much.
