When door is opened the fan and turntable start. From reading here sound like door switches need replacing. Which ones do I need? Fairly good at simple fixes, is this a DIY repair? What are the steps? Any tips to be able to test a solution before ordering parts? IE faking a door close to make sure it's the switch?

Terry for Model Number Maytag UMC5200AAB Microwave

ANSWER Hi Terry. The fan and the turntable are controlled by the primary switch part # 56001036 that has shorted closed causing the issue you have. It has the blk. wire and the red wire connected to it. Obviously it will react the same as if you removed both wires and jumped them together. You remove the upper grill. This will allow access to a metal cover plate above the controls, remove it. Then slide the control panel up and hinge out towards you. You will need to remove the green ground wire and note all wire connections to the board. This allows you to open the door and remove the inner side latch mount screws and lift the latch assy up and out from the inside of the microwave cavity. Then you can replace the micro switch in question. Thank You.
