Dave August 06, 2017 for Model Number SMH1816S/XAA-0000 When plugged in the microwave starts and cooks without programming time and pushing start. When open the door it stops but when you close the door it starts again with the buzzing sound of the magnetron like it is cooking. Is it the main pcb or a door switch?
1 Answer Hello Dave. You will need to test the door switches. If good, then you will need to replace the main board on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Joe April 05, 2017 for Model Number samsung 1816s microwave fan runs constantly, on and off buttons will not do anything. It will turn off when the door is opened, but starts back up when door is closed. I replaced the key pad last year when this same problem occurred and it fixed it, but did not work this time.
1 Answer Hello Joe. It sounds like a door switch is bad and will need to be replaced on the unit. You can test this with a multi-meter TJMA-DMT3.

Greg January 26, 2017 for Model Number SMH1816S/XAA-0000 The microwave makes a humming noise when you close the door even though no cooking instructions have been entered on the key board. I believe the faulty part is the pcb main assembly/relay control board. I will purchase the part number DE-02329F from you. Can you tell me how to disassemble the control panel to change the part?
1 Answer Hello Greg. Remove the grill off the unit. Then remove the screw securing the control panel. Lift upward and off the unit to remove it. You will need to test all 3 door switches. It sounds like one is bad on the unit. You can test this with a multi-meter TJMA-DMT3.
