How to Fix / Troubleshooting

Safety: Steam can cause burns; allow the unit to cool before inspection.

Steps:

  • 1. Clean door seal: Wipe the door gasket and the mating surface on the cabinet with a damp cloth to remove grease and debris.
  • 2. Check vents: Ensure steam vents are not blocked by objects or heavy grease buildup.
  • 3. Observe operation: Some steam around the door is normal, but heavy condensation or dripping indicates a sealing or venting issue.

Advanced: If the gasket is damaged or the door is warped, a technician should replace the door assembly or gasket with Sharp parts.
