Cooling Issue - Compressor Running
This diagnostic path investigates why the unit might not be maintaining proper internal temperatures even when the cooling mechanism appears to be operating.
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.
- Perishable product temperature exceeds safe range: Remove all perishable items immediately. Document temperatures and product affected.
- Compressor making unusual knocking or grinding noise: Stop compressor operation to prevent further damage. Escalate to refrigeration technician.
- If the unit still fails to cool after checking airflow and seals, this suggests a sealed system issue requiring a qualified technician.
- If the compressor makes unusual noises, immediately cease operation and call a qualified technician.
