Common Question:
How can I tell if the microwave control board module is bad/faulty/defective?
Answer:
One way to test to see, if the control board module is bad you would want to check for voltage going into the control board module and for voltage out. If there is voltage to the control board module, but there is no voltage coming out of the control board module then the module is faulty and would need to be replaced or repaired. However, sometimes the control board will power up, but certain components on the board could be bad and it will not work correctly on some of the devices features.
