Why Your Thermostat Screen is Blank

Have you ever gone to your thermostat to change the temperature, only to find a blank screen? It can be frustrating as the thermostat is relied on to control the comfort level of the home. You could have an HVAC system functioning correctly, but with no thermostat, it doesn’t matter. Why does your thermostat screen go blank and what steps can be taken to correct? Our team of HVAC maintenance professionals in Jacksonville, FL are here to help.

Diagnose the Issue

Work to diagnose the issue. Take some time to try out a few different standard problems thermostats face. Trial and error can help to eliminate the potential problems. The closer that you can get to the core issue, the quicker and easier it will be to fix.

Circuit Breaker

One of the first things you want to check is the circuit breaker. A circuit breaker may simply have tripped and cut off power to the thermostat. Go to the circuit breaker box and see if there are any tripped. If so, reset them and go back to check the thermostat. It may be on as simple as that!

Dead Batteries

Did you know batteries typically power a thermostat? The thermostat may have dead batteries. While older thermostats are hardwired, the new ones are not.

Swapping out the batteries on the thermostat is easy. Just remove the faceplate and swap them out. If you have an owner’s manual, it can be easy to use that as a guide to execute the task.

HVAC Issues

Our team of HVAC maintenance professionals has seen instances where the system itself has caused the thermostat to malfunction. Storms in Jacksonville, FL, even just regular wear and tear can deteriorate systems. If the transformer has stopped sending voltage to power the thermostat, you may have the blank screen issue. Our team can work to diagnose this and correct it quickly.

Broken Thermostat

The most obvious answer of all if it is none of the above is that its a broken thermostat. Just like all other types of little gadgets, electronics, they will break down over time! If you have a broken thermostat, replace it! You may feel confident to try this on your own, but if not we are here for the assist.

Just had an entirely new, full HVAC install done at our old house in Riverside, which was a fairly big job. Brian and... Will did the installation, and were awesome. There was going to be issues leveling the air handler in the attic, so they moved it to a new spot and hung it instead, getting new parts/changing the plan on the fly. We're much happier with this new setup and location of the air handler. I really appreciated this, their professionalism/thoroughness, and flexibility. Brian and Will worked super-hard, and double-checked everything once the job was done. Would use this company again.read more

Two installers here early this morning. Worked all day. Very professional, extremely well mannered and quick to answer... all my questions. They are Dustin and Robert. Both men went above just installing my new unit, they were personable and knowledgeable in what they were doing. I was surprised when I found out these two hadn't been working that long together. They worked extremely well together. I highly recommend this two men.read more

A snake crawled into my outdoor condenser and stopped my 16 year old Trane last week on Thursday. The power surge took... out my blower unit circuit board and the motor. I called J&W and Rob was over within two hours of my call. I was spec'd a new York 17 seer system and it was up and running on Monday. Technicians Jason and Brian arrived promptly and every facet of the installation was thorough. When completed, I would not of even known they were there except they left my garage cleaner! Thanks J&W!read more
