Annie P Jupiter , FL October 23, 2015 Appliance: General Electric Free Standing Microwave JVM1870WF02 Ge Microwave Jvm1870wf02: A small plastic piece supporting the microwave vent screws broke off. How to replace Microwave Vent Grille Assembly White. The removable unit was unscrewed from its support on top, and a replacement Grille Assembly for my 2005 GE Microwave oven model was found on AppliancePartsPros.com Easy as Pie! That is, if you remembered where you put the screws you removed, because the new Grille assembly does not come with replacement screws! Thank you to AppliancePartsPros.com for stocking this unit and making life easy for this DIY fixer! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
