Question about Honeywell CT3600 7 Day Electronic Programmable Thermostat Heater

1 Answer

Honeywell CT3600-AC not working

The AC is somehow not fully entering the house. It worked perfectly a month ago, and now my house does not get cold even with the cooling temperature set. The temperature has been rising and is past 80 degrees now, and is not decreasing. The AC seems to be running outside, however the temperature is still rising inside, and there is a very faint flow of cool air coming through the vents.

What could be wrong and how do I fix it?

EEE error message


I just talked to Honeywell support - they claim that an eee error means there has been a "unique error" and that the unit will need to be replaced - cannot be fixed. They were pretty good about giving a suggestion for a new thermostat and wiring directions if you want to DIY. Otherwise, call a pro.
