Commercial Microwave oven has steam coming out

Yes. Steam coming out of a Panasonic commercial microwave oven is normal during operation, especially when heating foods with high moisture content such as soups, vegetables, rice, pasta, or frozen meals.

1. Why steam occurs:
   • Microwaves heat the water molecules in food, producing steam.
   • Steam may escape through the door vents or exhaust openings, which are designed to release heat and moisture.
   • This is a normal part of the cooking process and does not indicate a malfunction.
2. When steam is considered normal:
   • Steam is visible only during or immediately after cooking.
   • The oven is heating moist or liquid-based foods.
   • There are no unusual noises, sparks, or error codes.
3. Recommended user actions:
   • Use microwave-safe, vented containers or loosely cover food.
   • Avoid overfilling containers with liquids.
   • Allow food to stand briefly after heating to release steam safely.
   • Keep vents clear and do not block airflow.
4. Summary:

   Steam is a normal byproduct of heating food in a commercial microwave. If operation is otherwise normal, no corrective action is required.
