Primary Door Interlock Switch

Hello Tony, Thanks for your question. It would be a good idea to test part number PS237015, the primary interlock door switch, for continuity using a multi-meter. If that test is positive, the most likely cause is the thermal fuse, part number PS239525. Remember to have the microwave unplugged and to have the capacitor discharged prior to testing or replacing the thermal fuse, as the thermal fuse can store a large amount of electricity even after your microwave is unplugged. Wear an insulated glove and use a screw driver with with an insulated handle to siphon out the excess electricity of your capacitor. I hope this helps.

Hi James, Thank you for the question.To find the defective switch you will need a multi meter to test them. All 3 can have the same symptoms. Good luck with the repair!

Hi Marie, Thank you for the question. The switch snaps in place and there are no screws required. Hope this helps!

Hi Joe, Thank you for the questions. In order to get to the switches you will need to remove the outside cabinet and grille vent. You will be able to see where the screw is holding the control panel in place. Once the panel is removed you can have access to the door switches. Hope this helps!

Hello Paula, thank you for contacting us. You can remove the top panel of the microwave, then there may be just one screw to remove the control panel. Then you can remove the old switch, just disconnect the wires and pull it out, then just snap in the new switch and connect the wires. Hope this helps!

Hello David, thank you for your question. Yes, we would recommend replacing the switches and checking over the interlock (the part the switches are mounted into) to be sure it hasn't shifted from its position. I hope this helps!

Hi Bryan, Thank you for your question. Before you begin any repair please unplug the appliance from the electrical outlet. Use a Phillips head screw driver to unthread the screws securing the grill. With the screws removed, open the microwave oven door then the slide the grill to the left and lift it up to remove. Next remove the control panel mounting screw then lift the control panel up to detach. Then remove the screw holding the inner access panel and then release the panel from the retaining clips. Now remove the screws holding the switch assembly. Depress the release tab and the actuator to detach the switch you are replacing. Disconnect the wire connector to fully release the old switch. Install the new door switch by first connecting the wire connector. Now position the new switch in the assembly snap it into place. Realign the switch assembly on the frame and secure it with the screws. Reinstall the inner access panel securing it with the screw. Now insert the control panel tabs to the slots in the frame and push the panel down. Secure it with the mounting screw. Insert the tabs of the grill into the frame and slide it to the right. Shut the oven door and then secure the grill with the screws. Plug the power cord back in and the microwave should now work. I hope this helps. Thank you and have a great day!

Hello Avi, thank you for your question. For this kinds of issue, the cause is almost always a bad door switch. We would recommend replacing the door switches which are PartSelect Number: PS237015 and PartSelect Number: PS237409. There are two of the Part #: PS237015 required for this unit. I hope this helps!
