Donna W San Leandro , CA April 12, 2018 Micro hood display indicated the filters behind the grill vent needed changing. I identified the name of the part from the manual diagram, typed it into AppliancePartsPros.com, double-checked the model to make sure it would fit (thank you, thank you for provide that double-check feature, which I'm sure has saved many other customers the trouble of shipping back the wrong parts and reordering the right ones), found a "how to" video on youtube, and set to work. I ended up having to replace the grill vent as well as the two filters behind it, because part of the grill vent cracked and wouldn't sit flush with the frame, which made the microwave think its door was perpetually ajar, so that the interior light stayed on and the fan kept running.
