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

April 13, 2021

The Nest thermostat is one of the most popular 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 using geofencing with your phone, the Nest Learning Thermostat and Nest E realize when you’re at your home 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 use the Nest thermostat compatibility checker before purchasing one. Don’t forget to contact your energy company 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 hook it up yourself or call a HVAC pro like Oak Grove Heating & Air Conditioning. If you’re wiring it yourself, 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 the majority of cases, Nest says this isn’t a problem since the thermostat can pull ample 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 Issues

The Google Nest Thermostat is better than older programmable thermostats that rely on a combination of wiring and AA batteries for power. It uses 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 Issues

If it can’t receive ample juice, Nest says you might have some of these troubles:

  1. Bad battery life.
  2. Thermostat motion sensing is disabled.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system abruptly 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 constantly 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 always working, won’t switch on or turns off and on repeatedly 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, we recommend you check your thermostat right away. This is especially pertinent if the weather is temperate, and you haven’t been running your heat or air conditioning frequently.
