coleman furnace?
Furnace runs, shuts off and comes title back on. Replaced the thermostat & that didn't supporter. Gas bill is going to be bad this month. Any ideas? gary
we have had the same muddle. i talked to coleman to see if it was one of the models that was recalled and it wasnt. they said several things could well-spring it. assuming it's a gas furnace, the upper limit flog could be switching it off because the firebox was getting too hot before it completeed it's heating cycle, once it cools it starts up again. the ducting could be meagre to allow the hot air to move out at a rate that will allow enough heat issue resulting in the upper limit switch tripping.
the thermostat could be in a place that warms quickly then shuts off snf cools moral as quick- they reccomend moving the thermostat. also if its on a fa wall it is cooling down too fast. they also reccomend making true the filters were clean and too not use the super efficient filters because they retard the inlet airflow.
our problem was when they installed the furnace, the installer dropped the furnace down and collapsed part of the ducting underneath restriciting airflow and causing a warm up excite buildup. it's better now - somewhat, and i have a thermometer that lets me see if the office is getting to temperature before it shuts off.
if you have a digital thermostat, are the batteries chattels and the low end models dont seem to work very well
hope it helps
