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

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 makes an energy-efficient schedule to match. And by geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your residence or gone and can raise and lower temperatures 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 wise idea to visit the Nest thermostat compatibility checker before purchasing one. Don’t forget to talk with your energy company for valuable rebates, because you may be able to get a Nest for free or close to it.

Once you’ve made sure it’s compatible, you can either wire it yourself or call a HVAC specialist like Three Rivers Heating & Cooling. If you’re wiring it 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 house or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t an issue because the thermostat can get adequate power from other heating and cooling wires.

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

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is better than outdated programmable thermostats that rely on a combination of wiring and AA batteries for power. It uses a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t get enough electricity, Nest says you might encounter some of these issues:

  1. Poor battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat sometimes disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t shut 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 notification on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is always running, won’t turn on or turns off and on rapidly 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, it’s best to start with your thermostat first. This is especially pertinent if the weather is temperate, and you haven’t been relying on your heat or air conditioning much.
