Help! My Thermostat Screen is Blank in Charleston, SC

If you get up to check that your Charleston, SC home is at the right temperature, only to see your thermostat screen is dark, don’t panic. This is a common issue, and it usually has a quick fix. Here are some steps you can take to figure out why your thermostat’s screen is blank.

Check the Power Source

First, verify that the thermostat is receiving power. If it’s battery-operated, replace the batteries. Many don’t realize that a dead battery is one of the most frequent causes of a blank screen.

If your thermostat is hardwired into your HVAC system, check the circuit breaker. A tripped breaker could disrupt power to the thermostat. Reset the switch by flipping it off and on.

Inspect the Wiring

In the case of a hardwired thermostat, you may have a broken or loose wire. You will need to call a heating and air conditioning professional to check if this is the case.

During the service call, the technician will first turn off your HVAC system. Then, they will remove the thermostat to check the condition of the wires.

Check the Safety Switch

Some heating and cooling systems have a safety switch at the unit or at the air handler. If your system has a drip pan and it’s full of water, the switch might be shutting it all down to prevent damage. Try emptying your pan out and resetting the switch.

Consider a Replacement

If you have a professional check everything and the screen is still blank, they will likely recommend a new thermostat. Older devices can erode and eventually aren’t accurate. Your best option is to replace it with a smart thermostat that can also help with energy efficiency.

Don’t allow a blank thermostat to cause you anxiety. A professional can help you find the root cause and restore your comfort in no time at all. Contact M & B Heating and Air for HVAC services today and get your thermostat working and your comfort back on track.
