So yesterday i ran a no cooling call. 5ton trane heat pump for a training room. Low pressures, 40deg superheat, no subcooling, flahsing sight glass, and going off on freeze stat. I charged the unit to 10deg superheat as specified by trane per the space and ambient conditions. Today no cooling. Go back out and compressor is dead. Pulling 91amps then tripping the internal. I weighed out the charge and i was dead nuts on the charge per the installers notes. I personally am ok with it but the account manager wants a detailed explanation as to why this compressor died. I dont beleive i did anything wrong but Im not perfect. Any one have an idea?
