So, how do you fix the no-display issue on your Honeywell Thermostat even after you have replaced the batteries? First, check the power, wiring, and reset the thermostat. The process was quite lengthy, but at least it got my thermostat working again.īased on my experience and research, I decided to compile a list of common go-to fixes that you should try if you find that your Honeywell Device is not working as it should. I looked through various forums and contacted the Honeywell support team several times before figuring out the issue with my thermostat. What I thought would be a simple fix turned out to be a lot more complicated. So I tried the easiest fix to this issue: replacing the batteries.Īfter I was done, I waited for a few minutes, but the display remained blank. Unfortunately, when I headed to the thermostat, I noticed the device wasn’t working as it should, and there was no display. So I thought to myself, “No problem, I’ll just change the settings on the thermostat!” I’m used to spending cozy evenings at home, but one day I noticed the evening was a little chillier than usual.
