I have had the thermostat turned to eighty and the furnace dies on -5 degree night in the windy city.
Nothing but cold air blowing.
I have had two repairmen over, one got the new
heater back on by simply shutoff switch, off for 10min then switched back on.
SEcond guy said my thermostat needed to be calibrated.
My question is if it is my limit switch how
do you adjust it and if I replace it, is it
plug and play or pray?
