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

April 13, 2021

The Nest thermostat is one of the best-selling smart thermostats you can get. And for good reason. It picks up on your temperature preferences and creates an energy-efficient schedule to match. And using 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 temps 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 smart idea to use the Nest thermostat compatibility checker before installing one. Don’t forget to contact your energy company for valuable rebates, as 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 contact a HVAC professional like Durable Service . If you’re installing it without help, you’ll notice 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. Most of the time, Nest says this isn’t a setback since the thermostat can draw ample power from other heating and cooling wires.

In some cases, 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The Google Nest Thermostat is a step up from outdated programmable thermostats that use a combination of wiring and AA batteries for power.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 turn on your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t get ample electricity, Nest says you could have some of these troubles:

  1. Poor battery life.
  2. Thermostat motion sensing won’t operate.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system unexpectedly turns on or off, or won’t stop running.
  5. Your system is making weird noises, like 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 message on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
  8. The system fan is always on, won’t turn on or turns off and on frequently in a short period of time.

You might worry something is suspect with your heating and cooling system, but if you just got the Nest, we recommend you begin with your thermostat first. This is especially pertinent if the weather is mild, and you haven’t been running your heat or air conditioning consistently.
