2003 Newmar Dutchstar dash Air not working properly

[B2900]

My dash air is not working properly yet I have a tempature of 41 degress at the condensor. I also have excellent pressure in my 34A refridgent When I put on my air I do get cold air for awhile then the air turns warm. Yet my condensir still is reading 41 degrees? Does anyone have any suggestions?

I would be looking at your heater control valve especially if it's an Evans. You may be leaking hot coolant into the heater core and warming the air box.

B2900: I suggest you look at : http://www.evanstempcon.com/pdf/ccl/evtg.pdf

especially the proceedures on page 2. The problem is likely to be the hot water control valve, which is easy to check (by clamping a hose) and not too costly to replace. Good luck,

Some of us installed a ball valve in one of the heater hoses.

Check the condensation line to make sure it's draining it is possible the condenser is freezing up after runing awhile. If no water drains shut it down and after a few minutes check for drainage again. Jim
