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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats on the market today. And for good reason. It picks up on your temperature preferences and develops an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your house or away and can change temps to help you save even more.

The Nest is compatible with a vast range of 24-volt heating and cooling systems, but it’s always a good idea to check the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy company 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 without help or contact a HVAC pro like Garoken Energy Co. Inc.. If you’re installing it without help, you’ll see a terminal for the C-wire, or common wire. This wire is solely 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 a setback because the thermostat can draw enough power from other heating and cooling wires.

In some cases, your heating and cooling system could need that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is an improvement from aging programmable thermostats that use a combination of wiring and AA batteries for power. It has 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 draw adequate juice, Nest says you may encounter some of these problems:

  1. Poor battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t stop running.
  5. Your system is making strange noises, such as 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, like “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly running, won’t run or turns off and on frequently in a short period of time.

You may believe something is wrong with your heating and cooling system, but if you just installed the Nest, we advise you begin with your thermostat right away. This is especially true if the weather is mild, and you haven’t been relying on your heat or air conditioning much.
