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

April 13, 2021

The Nest thermostat is one of the most popular smart thermostats you can get. And for good reason. It figures out 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 out and about and can adjust settings to help you save even more.

The Nest can be used with a vast range of 24-volt heating and cooling systems, but it’s always a good idea to visit the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy provider for valuable rebates, since you might be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either hook it up on your own or contact a HVAC pro like House of Heating Incorporated. If you’re putting it in yourself, you’ll see 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. In most cases, Nest says this isn’t a setback since the thermostat can get ample power from other heating and cooling wires.

In some instances, your heating and cooling system might have to have that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Issues

The Google Nest Thermostat is an improvement from outdated programmable thermostats that use a combination of wiring and AA batteries for power.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

  1. Bad battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t turn off.
  5. Your system is creating weird 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, along the lines of “heating is delayed for 2:30 minutes.”
  8. The system fan is always working, won’t run or turns off and on frequently in a short period of time.

You might worry something is wrong with your heating and cooling system, but if you just started using the Nest, we advise you check your thermostat right away. This is especially timely if the weather is temperate, and you haven’t been using your heat or air conditioning consistently.
