Why is there condensation on your Samsung microwave door?

It is normal for condensation to form inside the microwave, especially when heating or cooking foods with a high water content such as vegetables, soups, or frozen meals. This can also include moisture that appears between the glass panels of the door.

This condensation will usually disappear on its own after cooking. To help it evaporate more quickly, you can leave the microwave door open for a short period after use or wipe away visible moisture from the interior with a dry, soft cloth once the microwave has cooled.

Condensation on the outside of the microwave is caused by moisture in the surrounding air, not from inside the microwave itself. This is especially common with over-the-range models when cooking on the cooktop below, particularly when boiling water. Steam rising from the cooktop can collect on the microwave's exterior and may sometimes enter the door or appear between the glass panels.

To reduce this type of condensation, use lids on pots and pans when cooking and turn on the microwave's hood vent while using the cooktop. Ensuring proper ventilation in your kitchen can also help limit the amount of moisture that builds up around the microwave.
