This Over-the-Range Microwave Grease Filter traps grease from the exhaust air of your oven to prevent it from entering the blower and vent, potentially causing build-up and damage. If your current filter can no longer be cleaned and is not functioning properly, replacing this accessory may alleviate these issues. This chrome filter is a universal part that can be used across several brands; check to see if your model number is compatible. Installing this accessory will require no disassembly or repair experience. You must unplug the microwave or shut off the house circuit breaker for the appliance before installing.
