Possible Causes

Blocked or restricted vents, High humidity cooking without venting, Faulty exhaust fan on OTR models, Damaged door gasket or inner door liner

How to Fix / Troubleshooting

Safety First: Condensation itself is not dangerous, but always unplug the unit before removing covers.

  • Use vent fan: On over-the-range JennAir microwaves, always run the exhaust fan during high-moisture cooking.
  • Check vents: Ensure interior and exterior vents are not blocked. Clean grease filters regularly.
  • Wipe dry: After heavy steaming, open the door and wipe down the interior with a dry cloth to prevent long-term moisture damage.
  • Inspect door seal: Check the door gasket and inner door liner for cracks or warping that could allow excess moisture to escape into the door assembly.
