Thanks for the info concerning finding a freon leak Don. That will be my next task. This evening I got two 12 oz cans of freon in the system, which got the compressor running but still no cool air out of the vents. In 2016 the Freightliner shop that did the repair claimed they extracted 1 1/2 lbs and re-installed 3 1/2 lbs so I'm going to get a new gauge to see how much more I will need since the compressor is now running.

Took ours into North Trail for dash air issues. The compressor would click on and off which I recognised as a low refrigerant condition. They told me the system had the wrong amount of refrigerant from the factory and it was a known problem, so they evacuated the system and recharged (no cost to me). So far it works great, but I'm keeping an eye on it. I have lived long enough to realize you can't believe everything a service center says.

I still don't know how many pounds of Freon mine should take. It originally looked like 3 pounds written on the evaporator up front, but during this last repair, Freightliner said they called Newmar and spoke to the A/C specialist who told them the coach takes 7 pounds.

All I know, my A/C is putting out 39 degrees at the vent closest to the radio.

There is an older document from Newmar labeled SS2011 (Newmar Evans technician Training) that details troubleshooting of Evans/Tempcon systems. Within that document are capacities for Freightliner and Spartan. Although dated 2006 it's probably reasonably accurate based on the likelihood that hose lengths and components are probably the same.

For instance, a Freightliner takes either 3.5 LB or 4.5 LB depending on front/rear condenser and type of condenser (fin+tube or parallel flow).

Freightliner Rear Mounted Evans Fin & Tube Condenser = 4.5 LB.
The other configurations = 3.5 LB.

Spartan chassis' have more configurations and capacities of 3.0, 3.5, and 4.5 LB.

Newmar may have a more recent document ... I haven't looked since I have a 2005 vehicle.

Just to make things more complicated the New Aire requires 6.0 lbs.
