How to Fix a Blank Honeywell Thermostat

Picture this: You walk up to your thermostat to adjust the temperature in your home, only to be greeted by a blank screen. You tap on it and press the buttons — still, nothing. Since your thermostat is the control center for your HVAC system, you can’t afford to go too long without it working properly.

What To Do if Your Honeywell Thermostat Screen Is Blank

Check the Batteries

Remove and replace the batteries from your Honeywell system as directed in the instructions for your specific model. The batteries may be within your battery compartment or control panel. Be careful to make sure they are correctly oriented within the thermostat. Once replaced, test the system for operation and responsiveness. 

Check Your Breakers

If your breaker trips, go to your electrical panel and flip the breaker back into position. This should resolve any issues. However, if it continues to trip, it can indicate an electrical fault that a certified electrician should inspect.

Check the Safety Switch on Your HVAC System

Your compressor has a safety switch that monitors refrigerant pressure. If pressure falls too low or rises too high, it shuts the system down to protect the compressor from damage. It is typically located on the unit’s discharge line. Checking the safety switch should be done by a professional who can create the necessary conditions to test the switch function safely. However, if you have a manual switch, you can toggle this to reset the switch quickly and effectively.

Restart Your Honeywell Thermostats

Proper restarts require adherence to the following steps in order:

  1. Ensure the thermostat is switched “on.”
  2. Depress and hold the Menu button down for five seconds.
  3. Scroll through the menu and select “Reset.”
  4. Scroll to and select “Factory.”
  5. Confirm your selection by pressing “Yes.” 
  6. Congratulations! Your thermostat should reset at this point.
