Atwood 8535 Furance issues
Hello I am new to the RV.NET world. I am having a issue with the furnace in our fifth wheel. Its a Atwood 8535-IV-DCLP. My issue is this, the furnace will run perfectly fine, but after a few days ...

1. You do not have to go to the furnace to reset after the 3 try lock out. Just turn the interior tstat OFF for 10 seconds. THAT will reset the Ignition module
2. You probably have 2 LP regulators if you have 2 LP tanks on opposite sides of the RV. You must have a 5th wheel?
3. IF you have 2 LP tanks NOT next to each other, the LP tank that is NOT next to the LP regulator will have a HI PRESSURE regulator in line from that tank to the other side where it connects to the Auto switchover LP regulator. That regulator drops the HI pressure down to lower pressure to prevent a HI pressure volume leak if that LP line from that side to the other side ever had a leak.
4. Yes, Lower Liquid level in a DOT tank "can" have vaporization problems when the Liquid level drops. That usually means you have excess air in tank which is hard to get that to happen, or you have moisture in the tank. Vaporization is a factor of exterior heat. The Liquid level should have no problem if you are above 50 degrees ambient. Lower Liquid level will cause vaporization problems is lower freezing type temps. If you do not swap out your tanks but refill your tanks, you may have to have them drained and purged to get rid of any air or moisture. Doug
