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 you can buy. And for good reason. It learns your temperature preferences and creates 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 gone and can raise and lower settings to help you save even more.

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

Once you’ve confirmed it’s compatible, you can either hook it up yourself or call a HVAC professional like A2Z Air Inc. If you’re putting it in on your own, you’ll see 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. In most cases, Nest says this isn’t an issue as the thermostat can draw ample power from other heating and cooling wires.

In some cases, your heating and cooling system might 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The Google Nest Thermostat is an improvement from outdated programmable thermostats that have a combination of wiring and AA batteries for power.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 run your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t draw ample power, Nest says you might have some of these problems:

  1. Short battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is producing weird 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 notice on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is always on, won’t switch on or turns off and on repeatedly in a short period of time.

You might believe something is up with your heating and cooling system, but if you just started using the Nest, it’s best to begin with your thermostat right away. This is especially pertinent if the weather is moderate, and you haven’t been running your heat or air conditioning much.
