Frank O Columbia , SC March 14, 2015 Appliance: Model GEMICROWAVE One of the wheels on the undercarriage came off and could not be replaced The simplist repair ever. Replaced the old with the new guide roller. The only surprise was the part arrived in less than half the time I expected it to take. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
