Door Switch

Hello Jeff, Thank you for the question. Yes, the most common part replaced for this issue is the door switches. You can test for continuity with a multi meter as well before replacing the switch. Thank you for your inquiry, good luck with this repair!

Hello Gregory and thanks for writing. It sounds like a faulty Door switch PS12071302 check and replace if needed. We hope this helps. Please contact us anytime.

Hello Jake, thank you for your question. Yes, this is the middle switch, Part Number: PS12071302. Good luck with your repair!

Hi Shirley, thank you for your question. It could be yes. There are a few parts that could cause this issue however. You may also want to check your two other door switches and your fuse as well. Good luck with your repair.

Hello Tom, Thank you for contacting us. We have researched the model you have provided and have found the part you are looking for is Part #: PS12071302 and Part #: PS12071303 (two required) for the Door Switches. The Fuse is PartSelect Number PS12071294, To access the Fuse you will need to remove the appliance from the mount and remove the screws at the back of the appliance to remove the casing of the appliance. We hope this helps!

Hello Josh, thank you for your question. You can test your door switches with a multimeter. First, unplug your microwave. Some door switches have only two metal prongs extending from the body, while others have three. Those with three terminals will have a common (COM) terminal, a normally closed (N.C.) terminal, and a normally open (N.O.) terminal. Those switches with only two terminals will have either a common terminal and a normally open terminal, or a common terminal and a normally closed terminal. We are providing directions for testing a door switch with three terminals. If you are dealing with a door switch that has only two terminals, ignore the part of this test that does not apply to you. Using caution, remove all wiring harness leads from the switch's terminals. Use your ohmmeter to test your switch for continuity. Begin by setting your ohmmeter to measure resistance at a scale of Rx1. If you are using an analog meter, touch the metal tips of the test leads together and zero your ohmmeter by adjusting the thumbwheel in the front of the meter until the needle reads '0' on the scale. Touch one meter lead to the COM terminal and the other lead to the N.O. terminal. Do not push in on the actuator. Your meter should give a reading of infinity, meaning the circuit is open, and there is no continuity. Without moving the meter's leads, press down on the actuator until you hear a 'click'. With the 'click' of the actuator, the meter should produce a resistance reading of zero ohms. This means the circuit is closed and continuity is present. (switches with only two terminals do not 'click' when actuated) Keep the meter lead that is touching the COM terminal in place, but move the other meter lead from the N.O. terminal to the N.C. terminal. You should receive a reading of infinity when you push in on the switch's actuator. When the actuator is released, you should receive a resistance reading of zero ohms. Now, set your ohmmeter to its highest resistance scale and touch one meter lead to the N.O. terminal and the other meter lead to the N.C. terminal. The resistance reading between these two leads should be infinite. Finally, take a resistance reading from both the N.C. terminal and the N.O. terminal to any metal mounting hardware that is a part of the switch assembly. You should receive a normal reading of infinity. Any readings that differ from the ones presented here are indicative of a defective door switch that will need to be replaced. Door switch part number PS12071302 and Switch part number PS12071303. We hope this helps.

Hi Keith, thank you for reaching out. The door interlock switch, part number PS12071302, prevents the microwave from starting when the door is open. You need to check the door interlock to fix this issue. We hope this helps!

Hello Allan, thank you for a very interesting question. Your model comes with 3 door switches. Two door switches have the same part number PS12071303. The third door switch is part number PS12071302. You may need to check them all for continuity and replace the faulty one accordingly. We hope this helps.

Hello Patrick, Thank you for contacting us. We show that this model uses two of part# PS12071303 and the middle switch is part# PS12071302. If they are constantly failing, then you may have a wiring issue or an issue with the control board. We hope this helps.

Hi Daniel, thank you for reaching out. Based on our research, the issue is most probably because of the door switch, part number PS12071302. We would suggest replacing the door switch to fix the issue. We hope this solves your problem!
