Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
i have no lcd display on my timer, can you, help
Is the buttons still working, eg, boost, on/off etc? or is the heating not working?
If so the LCD/Control panel may have lost power, this usually a switch/or fuse that may have been accidently powered of or blown
