Why Your Nest Thermostat Isn't Operating Right and How to Repair It

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It figures out your temperature preferences and creates an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your residence or out and about and can change settings to help you save even more.

The Nest works with a vast 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 contact your energy supplier for valuable rebates, because you might be able to get a Nest for free or close to it.

Once you’ve checked it’s compatible, you can either install it on your own or contact a HVAC specialist like West Jefferson Plumbing and Heating, Inc.. If you’re putting it in on your own, you’ll see a terminal for the C-wire, or common wire. This wire is only used for powering your thermostat. If your residence or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t a problem since the thermostat can draw enough power from other heating and cooling wires.

Sometimes, 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The Google Nest Thermostat is an improvement from outdated programmable thermostats that have a combination of wiring and AA batteries for power.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 run your heating and cooling system.

8 Common Nest Thermostat Malfunctions

If it can’t draw enough electricity, Nest says you might run into some of these troubles:

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat every now and then disconnects from Wi-Fi.
  4. Your system abruptly turns on or off, or won’t shut off.
  5. Your system is creating odd noises, including 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 notification on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly on, won’t switch on or turns off and on rapidly in a short period of time.

You could believe something is up with your heating and cooling system, but if you just started using the Nest, we advise you start with your thermostat first. This is especially timely if the weather is mild, and you haven’t been running your heat or air conditioning consistently.
