How to Check a Microwave Seal
- 1). Clean the microwave oven thoroughly, paying special attention to areas around the door. Burned food, food crumbs and leftover debris can all get trapped in the microwave oven door's seal, causing the seal to function poorly. Wipe down the ventilation areas with a damp rag, removing any debris. Inspect the seal for tears or damage.
- 2). Close the microwave oven door and visually inspect the seal for broken, torn or warped areas. If the seal exhibits signs of wear, contact an authorized repair center for replacement.
- 3). Place a cup of water in the microwave and turn the unit on. Run the wand of the FDA-approved meter around the door seal and around the vents or openings in the microwave. If a high reading is detected, shut off the microwave immediately and contact an authorized repair service. Do not use the microwave until it is repaired.
