I have a gas(propane) furnace. It has a glow plug, which a automatic ignition. The glow plug lights up and the furnace kicks on but about a minute or two after it will turn off. There is no fire that is on and I know there is propane going to the house. Can anyone help me out. Furnace brand is an air bear.

No Air Bear furnace listed in the master file as a furnace only a air cleaner. Provide exact model number and I will check again.
