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

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats on the market today. And for good reason. It figures out your temperature preferences and develops an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your residence or out and about and can raise and lower settings to help you save even more.

The Nest works with a vast range of 24-volt heating and cooling systems, but it’s always a good idea to use the Nest thermostat compatibility checker before getting one. Don’t forget to contact your energy company for valuable rebates, since 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 without help or hire a HVAC pro like Appalachian Heating. If you’re putting it in without help, you’ll spot a terminal for the C-wire, or common wire. This wire is only 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 setback because the thermostat can pull adequate power from other heating and cooling wires.

In some cases, 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 a step up from aging programmable thermostats that have 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 turn on your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t draw adequate juice, Nest says you may encounter some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is making weird noises, including 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, 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 worry something is suspect with your heating and cooling system, but if you just got the Nest, we recommend you begin with your thermostat initially. This is especially timely if the weather is mild, and you haven’t been running your heat or air conditioning frequently.
