- Locate the charcoal air filter compartment on your microwave oven. This is typically found behind the grille above the microwave door or inside the microwave cavity, depending on the model.
3.2. Filter Replacement Steps
The exact steps may vary slightly depending on your specific microwave oven model. The following provides a general guide:
