Honeywell CT3600/CT3697 Programmable Thermostat No display. Changed batteries, cleaned terminals. Nothing. Suggestions?
Its had this problem off & on in the past but I could always get something by jiggling it.
This time nothing. I see replacements are cheap but is it possible to get one where I don't have to remove the backing that is already there? I just want my heat to work. I hate the darn thing. It has like 9 and 4 pins in the back of it.
Already replaced the batteries even thought told one ones were not dead.
And just like that, out of nowhere, it started working again. Better cancel the walmart pickup order.
