Jccam, just wondering if the service tech tapped into the system. This way he could tell whether or not you were low on charge or had a restriction in the system. You can replace the compresser on this model. It has to be done by a epa certified technician. Part number for the compressor kit is 2212192. You can see if it would be cost effecient at this link http://www.repairclinic.com/0080.asp Catriver post back.
