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 buy. And for good reason. It picks up on your temperature preferences and makes 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 house or away 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 smart idea to check the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy supplier for valuable rebates, as you might 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 on your own or contact a HVAC pro like Wolfe & Sons Heating and Cooling. If you’re installing it without help, you’ll notice a terminal for the C-wire, or common wire. This wire is only used for powering your thermostat. If your house or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a setback since the thermostat can pull ample 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 better than aging programmable thermostats that have a combination of wiring and AA batteries for power. It has 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 Malfunctions

If it can’t draw enough power, Nest says you could encounter some of these problems:

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system suddenly 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 constantly turning on and off in a short period of time.
  7. There is a delay notice on your Nest thermostat’s screen, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously on, won’t turn on or turns off and on repeatedly in a short period of time.

You may worry something is wrong with your heating and cooling system, but if you just got the Nest, we advise you begin with your thermostat right away. This is especially true if the weather is temperate, and you haven’t been running your heat or air conditioning frequently.
