Dominic C Elk Grove , CA April 03, 2015 Appliance: General Electric Microwave PVM1790SR1SS Ge Microwave Pvm1790sr1ss: Upper grill broken. How to replace Grille Ss. I found the part number on AppliancePartsPros.com. Ordered the part on a 3/29 paid via PayPal! the part arrived at my house on 3/31 and was installed that same day. I removed two screws at the on top front of the microwave cleaned out the broken tabs. Installed the new grill. All completed in under five minutes. It was cheaper and easier to go through appliancepartspros.com than to contact my warranty claims dept and have a tech scheduled to come out to tell me what's broken.
