Michelle D Peyton , CO October 08, 2016 Appliance: General Electric Microwave PVM1870SM3SS Ge Microwave Pvm1870sm3ss: The vent grill assembly was broken. How to replace Grille Asm, Ss. I ordered the part from the diagram. Item arrived quickly, unfortunately it was damaged. I called APP and spoke with a nice young lady that offered to send me a replacement out right away. New part arrived a couple of days later and was in great shape! I have ordered from APP in the past and will continue to go to them whenever I need an appliance part. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
