Microwave interior accumulates excessive condensation or moisture during and after cooking.

Safety: Allow the unit to cool before cleaning.

• Ventilation check: Ensure the external vent damper opens freely and that ductwork is not blocked.
• Use fan: On over-the-range Monogram microwaves, run the exhaust fan during and after cooking to remove steam.
• Wipe down: After cooking, wipe moisture from the cavity walls and leave the door slightly open to air dry.
• Fan operation: If internal fans are not running, have a technician inspect the cavity cooling fan and exhaust fan.
