I need help on a Carrier Gemini series split system heat pump (38ARQ). It has the Copeland Scroll with Advanced Protection System that allows the scroll to unload when high discharge gas temps are encountered. My proble is we have two identical units, one ok and the other the compressor is "unloading". We've cleaned everything, checked airflow, recovered and recharged by weight. After a few minutes of running the compressor will "unload" and continue to run. The pressures do not seem extreme and it has puzzled us. Anyne had this problem with the Copeland Scroll? I feel maybe the thermal disk in the comprssor is defective and allowing the compressor to unload prematurely. Any ideas? Thanks, Dwayne
