John for Model Number SCB1001KSS01 I am having an issue with the display on my Advantium microwave/speedcook oven. It only displays in the top two rows for about a second when a control button is pressed, then goes blank. While the oven is in use, the display flickers. The lower part of the display that shows modes (Oven Demo locked...) operates properly. While the oven is in use, the display flickers. Besides the display issue, the oven operates properly. I have run the resistance and voltage checks for the transformer and they are within spec. How should I proceed?
Answer John, the low-voltage transformer WB17X10021 (part has been discontinued by the manufacturer and is no longer available) would need to be tested for resistance after unplugging the power supply cord. The primary winding should measure 23.2 Ohms. Then the secondary windings would be tested from the yellow wire to the black wire for 1.5 Ohms, black wire to white wire for 5.2 Ohms, and red wire to brown wire for 1.1 Ohms. If they test well, the next step would be to verify that all wire connections at the control panel are secured properly. If the wires are secure, then it would most likely be a failure in the display control WB27X10858. Read More... Answered by AppliancePartsPros.com | Friday, April 12, 2024
