Scott K Danville , IL January 30, 2016 Appliance: General Electric General Electric WES1130DM2WW Ge Microwave Wes1130dm2ww / : Wheel fell off the original guide roller assembly. How to replace Guide Roller Ass'y. GE lists two parts with different numbers, Parts Pro's site illustrates two different parts with two different diameters. (The grid illustration is extremely helpful.)Chatted online with Paul from parts pro, determined which part would work and ordered it. Was a bit apprehensive about paying $7+ for shipping, but it was still a good bit cheaper than anywhere else, and in stock. Was shocked when it was delivered the very next afternoon; if I need any GE parts in the future, I'll definitely look here first. Installation involved pulling out the glass carousel plate, placing the guide roller assembly in the microwave floor, replacing the plate. Takes longer to type the procedure than to do it. I'm very satisfied with AppliancePartsPro in all respects. This is a first rate company. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
