Why does my Honeywell electric thermostat turn off?
Turns off with no display like it has no power. It's hooked up to a new box with 20 amp fuses and they are still good. I turn the power off with the switch on the fuse box and then back on and it works again. Happed twice. The thermostat is rated for 20 amps and the heaters are using less than that. Never blows the fuse too.
