I have a Honeywell CT31a thermostat that has just stopped working for no reason.?
When I push the temperature bar over to click on the heater it no longer switches on. If I take off the front panel there is a small bar with a sliding scale and notch that when I pushed down it did turn on the heater, but now nothing. Can anyone help?
sounds like you reset furnace control board by breaking the power to stat. some furnaces have a blinking small light that blinks to tell problem encountered by frurnace. but forgets if power is turned off.
