Plastic tabs broke off holding the vent grill

Parts arrived quickly and in good order. The plastic tabs had broken because of heat and excess cooking oils etc. Make sure it is kept clean. Take care loosening the screws holding the top of the grill(black) Easy to find and loosen. Take care that the broken tabs dont fall inside the frame as one of mine did. It does not seem to cause a problem. Installed new grill put two screws in and done.
