The machine works but several numbers on the keypad don't respond to touch. For example, only 1,2,3,4 work; press others and nothing happens. The clock works.
You will first want to pull the control panel and check the ribbon harness to make sure that it has a firm connection. You will also want to check for corrosion on the harness and if there is corrosion you will want to clean the terminals with rubbing alcohol. If this checks ok then you would need to replace the keypad assembly WB07X10871.
If The LED is not working is the smart board only item that need replacing?
Answer Hello Greg! Make sure that you have power to the microwave. You will need to replace the smart board WB27X10712. Thanks.
