Why This AVANTCO Cooler Isn’t COOLING | Compressor & Capacitors Check | 189BVAC28HC | Bad Comp

The video documents the diagnostic and repair process for an Avantco upright commercial cooler displaying operational failure, specifically an issue where the compressor is not running. The service technician begins by accessing the rear compartment to test components related to compressor startup. Initial testing indicated a failure in the compressor overload protector. After replacing the overload, the compressor remained inoperative, suggesting a deeper internal issue within the sealed system or the motor itself.

Further troubleshooting involved testing ancillary components, including the capacitors for both starting and running functions, all of which measured within acceptable operational parameters. The conclusive finding pointed toward a failure of the compressor unit itself, preventing the refrigeration cycle from starting. Due to the internal compressor fault, the repair was deemed unfeasible or uneconomical for the unit owner, resulting in a service call termination without the cooler being repaired.
