How to Fix a Blank Honeywell Thermostat

Posted on: August 28, 2015

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 can you do if your Honeywell thermostat is showing a blank screen? The first step is to check the batteries. It will flash a low battery signal for one to two months before they run out completely, but if you’ve been away or haven’t noticed the signal this could be the reason. Once you replace the batteries, you may need to reset the unit and reprogram your settings.

If your thermostat doesn’t run on batteries and is wired directly to your home’s electrical system, a blank screen may indicate that there is no power going to the unit. What can cause this to happen? It could be due to a tripped breaker or a problem with the wiring. If this is the case, contact the heating and cooling experts at ABC and we’ll come out to take a look and fix the problem!
