Possible Causes

Partial refrigerant restriction, Low refrigerant charge, Oil or moisture in sealed system, Poor contact between evaporator and tubing

How to Fix / Troubleshooting

Safety first: Do not attempt sealed system repairs unless properly certified. High pressures and refrigerant handling require specialized tools and training.

  • Step 1 – Clean condenser and verify airflow: Rule out simple airflow issues that can affect frost patterns.
  • Step 2 – Observe frost pattern: With panels in place and unit running, inspect the evaporator after 10–15 minutes. Uneven frost usually indicates a sealed system problem.
  • Step 3 – Call a professional: A certified technician will check pressures, locate restrictions or leaks, and perform evacuation and recharge per Viking specifications.

Homeowners should not open the sealed system; doing so can void warranties and violate regulations.
