What's wrong?
The Carrier Transicold Supra 950/950MT/960 refrigeration unit on the 2019-2023 Kentucky Trailer XL-12 keeps trailer cargo cold while the trailer is in service. Inside that unit, the centrifugal clutch transfers mechanical force from the diesel engine into the belt-driven parts that turn the compressor, standby motor, and alternator.
The recall addresses a clutch that can fail to deliver the required torque. That mismatch makes the clutch assembly overheat. If the heat continues, the clutch can fail severely and break apart inside the refrigeration unit, which is why the remedy centers on a clutch component that delivers the required torque.
Before full clutch failure, the alternator can stop providing the expected voltage level. That condition triggers an audible and visual alarm in the cab. If the alarm has not been disabled, it shuts down the refrigeration unit before overheating reaches the point of failure.
