Douglas F Port Clinton , OH April 20, 2015 The micro wave was arcing at the mica cover Repair man said we would have to replace the whole unit ., about $ 3,300. I identified the problem and went to your web site and found the mirco wave that matched and found the part I needed. The schematic in the web site was great , a part and number where shown. I placed the order and two days later it was in the mailbox. A $ 16.00 order that saved buying a new unit ( $ 3,300). Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
