Cooling Issue — Compressor Runs But Products Warm
This diagnosis addresses cooling performance problems when the refrigeration unit appears to be running but the dispensed products are not adequately chilled.
Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.
- All external checks pass but cooling is insufficient: Escalate to manufacturer-authorized refrigeration technician. Sealed system work requires EPA certification and specialized equipment.
- If external checks pass but cooling remains insufficient, escalate immediately to a qualified technician specializing in refrigeration systems.
- If any work involves the sealed system, it must be performed by a qualified technician holding the necessary EPA certifications.
