Why does my microwave door feel hot during use?

A warm door can happen during cooking, especially with longer heating times, but a door that feels very hot or shows new discoloration should be treated with caution. If the heat seems excessive, stop using the appliance until you have checked it. If the issue remains unresolved or safe use is uncertain, contact the retailer or store where it was purchased.

Check the cooking load

1. Use the microwave for a shorter period and compare the result.
2. Make sure the food is suitable for microwave cooking and is not overfilled in the dish.
3. Observe whether steam is building up heavily against the door.

If the door only feels mildly warm during longer cooking, that may be normal for the type of use.

Check the door and seal area

1. Inspect the door frame, seal and edges for visible dirt, damage or an uneven close.
2. Clean the frame carefully with a soft damp cloth if it is dirty.
3. Make sure the microwave is standing level and the door closes cleanly.

If the door becomes unusually hot, if you notice smoke, or if the door does not close securely, stop using the microwave. Do not touch the door for long periods if it is overheating, and do not attempt repairs. Please contact the retailer or store where the product was purchased.
