Norm October 09, 2019 for Model Number scb2001css03 micro oven The control board display is blinking and almost off but micro still works. What do I replace and how?
1 Answer Norm, the low voltage transformer WB20X10017 will need to be tested for resistance and should measure 22 ohms on the main winding. If it measures properly, then the secondary windings would need to be tested and should show a closed circuit. If the transformer tests good, then the main PCB board WB27X10394 would be suspected and can be tested by testing the incoming voltage at the display. If the voltage is erratic, then the main control has failed. If it is supplying a steady voltage, then the display board WB27X10431 has failed. Unfortunately, if the main PCB or display board are the cause, the manufacturer has discontinued these items and they are no longer available. Read More...
