No heat
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?...

Furnace is 12V DC power via FUSED circuit fed from DC Dist Panel and powered by converter IF on shore power source OR from Battery when NOT on shore power source.
Motor needs good 12V DC power to come up to full speed. Motor drives 2 fan wheels...1 side for combustion/exhaust and the other wheel is room air
T-stat calls for 'heat' ----motor starts....fan blows (cold room air) until 'timer' runs and 'sail' switch makes up (sail switch is safety device that has a paddle that sticks out into airflow stream)...enough airflow and paddle makes up allowing 12V DC to circuit board for gas valve and spark ignition.
Low 12V DC..low motor speed ..........no 'sail' switch making up/no DC for gas flow-ignition.
Furnace and HEATING......LOW 12V DC
Propane Indicator.
IT has failed.......time for new LP Regulator
You have gotten your monies worth out of that OLD regulator
Fact is......time to replace it AND the pigtail hoses that go from cylinders to regulator
Cavanga Regulators are very good quality
