Was using the furnace tonite but noticed the fan kept running but the air from the vents were cool. Swapped tanks but didnt make a difference. Got propane at the cook stove. What should i look for?...
mine went off on high limit due to lack of air flow. Pulled furnace out reset limit and reworked duct system . No issues now lots of air flow. It will kick it off once and every time you try to restart it will just blow cold air
