The metal grease filters trap the grease produced by cooking.
If they get damaged or break, or even get too covered in grease, this will cause deposits of grease to build up elsewhere in the appliance.
Unlike carbon filters, these metal filters can be cleaned. Therefore, and before replacing them, try giving them a thorough clean. If that proves insufficient, you'll need to replace them.
