We have a 2013 Loredo 329RE with a Coleman Mach 15 A/C unit (old model# 48254C866, replaced by 48204C866). The unit is blowing air, but not cooling. I had a local A/C guy that works on campers come by and look at it. He said the compressor is getting voltage, but not coming on. He is willing to replace the compressor if I can source the part for him. I contacted my local RV dealer and he stated that the compressor on that unit was not replaceable and that I needed to buy a whole new unit. I'm thinking the guy just wants to sell me a new unit. Does anyone know what the part number is and where I can get one?
