Your thermostat is the control center for your HVAC system. Programmable thermostats feature easy-to-read screens that allow you to program your heating and cooling settings and view the current temperature in your home. However, if that screen goes blank, you can’t do any of this. Honeywell and other brands of programmable thermostats typically show a blank screen when there is no power going to the wall unit.

Change the Batteries

A Honeywell thermostat will flash a low battery signal for about one to two months before the batteries in the wall unit run out completely. If you’ve been away or haven’t noticed this warning and the batteries can no longer provide power to the screen, it will go blank. This is easily fixed by removing the cover on the wall unit and replacing the batteries. You may have to reset the unit and reprogram your settings once the display returns.

Power Disruption

If your thermostat is wired directly into your home’s electrical system, a blank screen indicates there is no power going to the unit, which means there may be a tripped breaker or a problem with the wiring. If the breaker controlling the unit hasn’t tripped, contact an HVAC technician or an electrician to inspect the wires. Sometimes a loose connection is enough to stop power from running to the unit. If this doesn’t resolve the issue, have the thermostat replaced.
