How to Reset a Carrier Cor Thermostat

At some point, you want to reset your Carrier Cor Thermostat—especially if you’re having issues with it.

Of course, resetting your Cor Thermostat could help fix several issues such as incorrect temperature readings, not cooling/heating, and registration/Wi-Fi setup problems.

That said, in the following paragraphs, I’ll walk you through the steps to reset your Cor Thermostat and how to program some vital functions. Let’s begin!

Resetting a Carrier Cor Thermostat

Cor Thermostat Reset Instructions

Follow the steps below to reset your Carrier Cor Thermostat:

  1. On the Thermostat Home Screen, tap Menu, then select Settings and then select Reset.
  2. Now select Reset All from the reset options. Next, tap Yes to confirm the reset.

Note: This reset will restore default factory settings in your thermostat. What this means is, your registration details and Wi-Fi connection settings, including all other custom settings, will be permanently deleted. So you’ll have to start all over again to set up your thermostat. Go here to see how to register and connect your thermostat to Wi-Fi.

If you do not intend to perform a factory reset on your thermostat, select another reset option instead of “Reset All”. You may select “Reset Preferences” to only erase a few settings.

You can also reset your Cor thermostat by switching your HVAC circuit breaker switch off. Then wait 30 seconds and switch it back on.

You can find the HVAC circuit breaker switch in your home’s circuit breaker panel—usually labeled HVAC or Air Conditioner.

So that’s all about resetting your Cor Thermostat. If you’d like to learn more about setting up some key functions in your thermostat, keep reading.

Why did my Cor Thermostat go blank?

If your thermostat is battery powered, it might go blank if the batteries are low/completely drained. So replace your batteries and see if the issue is fixed.

You may also try rebooting the thermostat (even before replacing the batteries) to see if it turns on. To reboot your Cor thermostat, gently pull it from the backplate.

If your thermostat doesn’t run on battery power (mainly powered by your HVAC system), it might go blank if any of the wires are loose. So check the wiring and reconnect any loose wire.

If the issue persists, get an HVAC expert to run a check on it.
