I’ve got a 30 ton Carlyle condensing unit that out of nowhere blew the fusible plug on the suction line. Unit was calling for cooling, the TXV’s were good to go and the sight glass was indicating some flashing. Made repair and now my suction line is not getting cold or heating up. What may cause my suction line to overheat and fail like that? I’m not finding a significant temp difference at the filter driers either. This is an R407c+ unit. The Motor logic board is not indicating an alarm code.
