furnace blowing cold air

2007 Jayco jay feather lgt. Camper is being used on hunting property. The furnace is used a lot and has worked like a champ until this weekend, when it, upon start up would only blow cold air. Have plenty of propane. After switching tanks around, jolting them on the ground and tapping the regulator finally started to heat up, and ran fine the rest of the weekend. Could someone please tell me what this problem could be. Also the stove burners were lit but very low. Someone suggested that it could be the regulator. Any help will be greatly appreciated.

Sounds like you opened the valves on the tanks too fast .. it can cause them to freeze closed. Something weird with these new OPD valves. Just close them wait a min then open s-l-o-w--l-y.....

There is a check valve in the top of the tank that will close if a to rapid release happens. Like stated, just turn off vale and all appliances and in a min the ball will drop and your good to go. Same thing will happen if you put a new tank on a propane grill while the burners are in the open position and then turn on the gas.

I'm pretty sure there is also a safety feature in the pig tails. So to add to the above recommendation about turning the tank valves off for a minute, unscrew the pig tails (that short hose that goes from the tank to the regulator) and tap them on the tank valves a couple times, screw them back onto the tanks. Then open the tank valves VERY slowly (like stupid slow) and go test the stove again. If you're still getting a low flame, I might try the process one more time before I would be looking hard at the regulator.
