Why is My Thermostat Blank?

Have you ever woken up to a freezing room temperature or sweating profusely only to find out that your thermostat was blank? You’re standing there, staring at your thermostat, wondering what happened suddenly. Fortunately, that faulty thermostat is relatively easy to fix yourself compared to a broken air conditioner or furnace. Like any other device, your thermostat can display faulty behavior, but there are many steps you can take before calling the professionals. 

If you ever find yourself in this situation, here are the possible reasons why your thermostat has a blank screen:

• The device may be turned off
• The brightness of the display is low
• Its batteries are dead
• Incorrect or loose wiring or connection
• The voltage might have dropped
• Clogged air filters triggered the safety switch
• Too much dust or debris turned off the device
• There might be a blown fuse
• Recently replaced parts may be incompatible
• The thermostat is old, and it is time for a replacement

If you one of the listed reasons are messing with your thermostat, here are some steps to help you troubleshoot:

• Check if the device is on, it could have accidentally been turned off.
• Make sure the brightness isn’t tuned down or on the auto-dim setting.
• If you have a flickering display, replace the batteries.
• Wiring issues can be dangerous. Call in experts to assess the connections.
• Low voltage can impact the device’s performance. Check if there’s a tripped breaker.
• Dirty air filters can impede airflow and shut the system off. Change your dirty air filters right away.
• If the wiring of the HVAC system is dirty, clean it off, and it might solve the problem.
• If there’s a no other power issue, check and replace the blown-out fuse.
• If you’re using an old device, get a new, smart thermostat so you can save on your power bills and the system can run efficiently.

It’s important to fix your thermostat, so that you you can keep your family comfortable. If you aren’t able to fix it yourself, seek professional help.
