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

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats you can buy. 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 know when you’re at your home or gone and can adjust settings to help you save even more.

The Nest can be used with a wide range of 24-volt heating and cooling systems, but it’s always a smart idea to check the Nest thermostat compatibility checker before getting 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 made sure it’s compatible, you can either install it on your own or contact a HVAC specialist like Wallpe Heating & Cooling. If you’re installing it on your own, you’ll see a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your house or HVAC system is older, you might not have one of these wires. In most cases, Nest says this isn’t a problem since the thermostat can draw ample power from other heating and cooling wires.

Sometimes, your heating and cooling system may have to have that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is an improvement from older 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 operate your heating and cooling system.

8 Common Nest Thermostat Malfunctions

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

  1. Short battery life.
  2. Thermostat motion sensing is disabled.
  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 creating weird noises, including 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 message on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is continuously running, won’t switch on or turns off and on repeatedly in a short period of time.

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