Commercial grade microwaves produced by Menumaster are all equipped with an air intake filter. Menumaster recommends cleaning the filter at least once a week to avoid overheating and oven damage. A clean air filter improves air flow through the microwave. The oven must not be operated without the filter in place, as this could lead to the microwave oven being damaged.
Pull downward on the plastic tab in the center of the filter to release it from its holding tabs.
Pull the filter out and down to remove it from the microwave oven.
Submerge the filter in hot water. Add mild detergent to the water.
Scrub the filter gently with a soft cloth or sponge to remove any buildup or debris.
Rinse the filter in clean hot water to remove all of the soap.
Prop the filter up against the counter or wall to allow it to air dry.
Slide the filter back into the filter compartment of the microwave after it has dried. The filter locks back into place as it is pushed into its compartment.
