Corrosion and oil staining around the evaporator tubing raised concern for a sealed-system refrigerant leak.
| Appliance | Refrigerator |
|---|---|
| Customer complaint | Poor cooling or gradual temperature rise |
| Diagnostic finding | Sealed-system leak suspected at the evaporator area |
| Outcome | Pressure and leak testing used to determine repairability |
What the visual evidence suggested
Green corrosion, oily residue, or localized staining on refrigerant tubing can indicate a slow sealed-system leak. Visual evidence is important, but it should be confirmed with operating pressures, temperature measurements, and an appropriate leak test.
Why adding refrigerant is not enough
Recharging a leaking refrigerator without correcting the leak only creates a temporary result. The leak location, tubing condition, compressor operation, and overall age of the refrigerator determine whether sealed-system repair makes financial sense.
Repair versus replacement
An accessible evaporator or joint may be repairable. A leak inside the cabinet insulation is generally not practical to repair. The customer should receive a clear explanation before an expensive sealed-system job is authorized.
