Nicholas S Bryan , OH February 08, 2019 I picked up an old microwave but later discovered that the roller guide assembly that the turntable rotates on was broken I went online and quickly was able to locate a new one at Appliance Parts Pros. It was shown on a grid so that I could compare the size with my broken one. It was simple to order and arrived quickly as described. I appreciate a place that carries parts for the older appliances that I own. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
