Scott Y Zwolle , LA May 05, 2015 After a power outage advantium oven display control panel was blank oven unusable Found a service manual online. Used a volt meter to determine no voltage output from low voltage transformer which controls the display and circuit board. Went online to find the part. Installed it and oven is now working properly. As long as you don't remove the door or mess with the magnitron, oven can be safely repaired without special meters to measure microwave leakage. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
