Hello, Thank you for your question. If the microwave is turning on by itself when the door is closed, the issue is likely one of the door switches and you will need to test them with a multi-meter. As you will be testing electrical components, verify that you have unplugged your microwave before beginning. Locate and remove the door switch. You will need to remove the cabinet in order to access it. You should also inspect the door hooks that trigger the door switch to verify they are activating the switch mechanically. To test the switch for continuity, set your multi-meter to Rx1, depress the actuator button and touch the terminals with the probes. You should receive a reading of 0, indicating that there is continuity. If your switch does not have continuity between the terminals, you will need a replacement door switch. We hope this helps. Thank you and have a great day.

Hello Gary, thank you for your question. Unfortunately, if the beeping sequence was programmed that way when the unit was produced it cannot be changed.

Hello Michelle, thank you for your question. The door assembly is Part #: PS2582994. I hope this helps.

Hello Walter and thanks for writing. If your microwave continues running when you open the door, it may be a problem with the door interlock switch.PS12071302 ... The components that could stay on when the door is open, but the door switch isn't working are the fan motor, stirrer motor, and interior light. We hope this helps. Please contact us anytime.

Hello Zandra, thank you for your question. We would recommend replacing the charcoal filter PartSelect Number: PS2203386 as well as the grease filters PartSelect Number: PS1993472, and also check the door switches. Bad door switches could cause the fuse to blow as well. I hope this helps.
