The difference between a "Mobile Tech" and a qualified RV tech would have found the problem.
1. IF you have a problem cooling on LP and all other causes have been checked and the refer is in a slide room, The hose routing is always checked.
2. A KNOWLEDGABLE qualified RV tech would have connected the Manometer at the refer valve and checked the LP pressure at the refer. THIS would have indicated a supply problem. And if knowledgeable, would have suspected the hose routing as this is a common problem on RV's with refers in slide rooms. Doug
