Oasis Heater Problem

[HaroldStew]

I have a 2008 Newmar Mountain Aire with a Oasis hot water system. In the dash I have a zone failure light on. In the water heater bay I have 2 red lights on the control unit. One on the winter solinoid valve and one on the winter pump. Originally it was just the solinoid valve. Anyone know whe the solinod vave is located? if i can find it i should be able to detirmine the problem.

You would have to post pictures of that setup. The pumps should be in the distribution module if they used one back then. The burner was usually separate from the pump module. Check for a distribution module behind the burner in the bay somewhere.

Both the solenoid valve and the winter pump can be replaced easily. First you want to go to the OASIS ITR website and see the troubleshooting guide for your particular unit. The new units have different control boards. Next, the guys at OASIS ITR in Vancouver, WA are fabulous on the phone. Give them a call and they can walk you through the fix.

Go to the other side (passenger side) , it is in behind a false wall that is easy to remove. there is another module, pumps inside.. I am using my 2012 MADP 4336 as the example. Hope this helps, good luck... Jim 75
