Gauge readings far below normal R134a pressures confirmed a sealed-system refrigerant leak.
| Appliance | Refrigerator |
|---|---|
| Customer complaint | Poor cooling or gradual temperature rise |
| Diagnostic finding | Refrigerant pressures below specification — sealed-system leak confirmed |
| Outcome | Pressure and leak testing used to determine repairability |
What the gauge readings showed
With the compressor running, the manifold gauge showed low-side and high-side pressures well below the normal range for an R134a system, while the cabinet stayed warm. That combination points to lost refrigerant charge — a sealed-system leak — rather than an airflow, defrost, or fan problem. An electronic leak detector is then used to locate where the refrigerant is escaping.
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.
