Question about Honeywell CT87B ROUND HEATING&COOLING MECHANICAL THERMOSTAT - WHITE Heater
Our honeywell thermostat, 3 years old, no longer turns on the heat. temp has dropped to 62 and it is turning much colder tonight. we don't believe it is broken. is there something we can look for, or jiggle, or anything that might 'jump start' the thermostat? a 're-set' button? Help!
If you tip the mercury switch so that it makes contact and the furnace
doesn't start, it isn't the t-stat. Check the connections, then
start checking the furnace.
In any case, ditch the mercury t-stat (recycle it properly) and get a new programmable one if at all posible. It will pay for itself many times over by turning your heat down in the middle of the night and back up by morning.
