Why Your Nest Thermostat Isn't Running Right 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 picks up on your temperature preferences and develops an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E know when you’re at your house or out and about and can change settings to help you save even more.

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

Once you’ve confirmed it’s compatible, you can either wire it on your own or call a HVAC pro like Cool Power LLC . If you’re installing it yourself, you’ll notice 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. Most of the time, Nest says this isn’t a problem since the thermostat can get enough power from other heating and cooling wires.

Sometimes, your heating and cooling system might require that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Problems

The Google Nest Thermostat is an improvement from outdated programmable thermostats that have a combination of wiring and AA batteries for power.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 link to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Problems

If it can’t draw adequate electricity, Nest says you might experience some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t shut off.
  5. Your system is producing strange 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 message on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously running, won’t run or turns off and on rapidly in a short period of time.

You could think something is suspect with your heating and cooling system, but if you just installed the Nest, it’s best to begin with your thermostat first. This is especially true if the weather is temperate, and you haven’t been relying on your heat or air conditioning consistently.
