In this video, Joshua Griffin goes through some of the reasons your thermostat may be blank. Some of these issues you may be able to resolve yourself and some may require you to call a pro. Regardless of what the problem is, thermostats being blank, or sometimes a good thing.

Thanks for sharing your knowledge. My buddy called me this afternoon (only 95 today) to tell me that his thermostat screen was blank. Thanks to your video I was able to suggest that he check his Float Switch. Sure enough, all he had to do was give it a twist and his system is back online. His house was only up to 81 .... but it wouldn't have been a comfortable night's sleep.

The float switch was exactly what caused our system to kick off. Thank you for mentioning it first!

Sir... I sincerely thank you! It's a cold Sunday morning in December. We woke up to no heat and a blank thermostat. Your video guided me to a simple solution: a pair of double A batteries. Thank you again!!!

Thank you! The problem was the float switch. I opened it to pour in some ac build up remover. Was getting super frustrated and tried wiggling around and reinserting the tab for it and it worked.

Thank you, you just saved me and my family $$$, ended up being a little moisture in our drain line causing the switch to show water... drained it and we are good to go!!! Again, THANK YOU VERY MUCH!!!

My thermostat goes blank most of the time, and comes back on occasionally. Any ideas on what to do?? Thanks I replaced the batteries, same deal.

Thank you, son, for this video. My thermostat is brand new (less than a week installed), and went blank. I know it is hard-wired, but I put batteries in it and it came back on, so at least for tonight it is working. I have a technician coming in the morning.

Thank you for the video. My central air unit/furnace shut down like it should because my p-trap was completely clogged. I replaced the p-trap with an E-Z trap and the AC has been working great. The water is supposed to drain to the outside of the house, but I don't see any water coming out. I heard that there should be about 1 gallon of water draining every two days. I live in a fairly new single level house. There's no water leaking around the central air unit/furnace or in the rooms beside the furnace closet. Where's the water draining? Should I be concerned? Thank you.

I got up for work, and my house was super hot like 85 with thermostat set at 73. So I checked, and my thermostat is blank and replaced the batteries and still blank, but the furnace was still going and blowing hot air... probably way hotter than it's ever blowed. So what would cause this as once I got to the basement the furnace stopped blowing

My daughter just bought a house. The Carrier unit, when heat is on... will start making a random clicking noise. We noticed when it started clicking, the thermostat is blank. It's an old school thermostat. We have to flip it to off then back on to get the thermostat to wake up. Not sure what is going on with it.

I have a serious question that no tech seems to be able to answer. What causes the compressor to make a rough sound when it kicks on? It seemed to stop at one point when it was recharged after i had a leak. But then it starting making that loud sound on start up again in just a few days. I live in FL and findging a good, honest tech that doesnt rip you off is hard.
