Ken N The Woodlands , TX January 20, 2023 Appliance: General Electric Free Standing Microwave SCB1000KBB01 Ge Microwave Scb1000kbb01: Unreadable flickering display microwave still worked on express. How to replace Pcb Electronic Power Board. Replaced the Power Board and Transformer based on another customer's experience. I hired an appliance repair tech to do the work mainly because the microwave was built in and had to be lifted out of the wall. I probably could have done the repair, but it would have taken me longer. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
