How can I remove the glass of the door.
For model number PEM31SM4SS
Hello Dolores, Thank you for the question. very sorry, since we do not sell the Glass separate from the Door, we do not have installation instructions for this particular part. For more specialized assistance or to speak with someone about this, I would suggest calling the manufacturer of the appliance directly. We hope this helps!
Often when cooking is complete and door is opened, the unit goes dark as if power was lost. After a few minutes it lights up again and after the clock is reset the unit works normally. There is no problem with house power (breaker). I like the unit so is this something I can repair? Thanks.
For model number PEM31SM4SS
Hi Paul, thank you for contacting us. We suggest testing each switch to see what switch needs to be replaced. Your model has three door switches, the two secondary door switches are the same. The secondary door switch is part number PS237421, it should read normally open, and the monitor door switch, part number PS237422, should read normally closed. Good luck with this repair!
My LED display is dying, what part do I need to correct this issue? Thank you,
For model number PEM31SM4SS
Hi Sam, thank you for the question. Based on our understanding of the issue, we would suggest checking the electronic control board, part number PS2339853, as it is the most likely cause of this issue. We hope this helps!
I ordered a microwave cooking tray from PartSelect; userfriendly site; and within two days, my part was delievered and easily installed. Thank you PartSelect!
Noted on partselect.com that someone else with this problem, found it to be secondary door switch. There are three door switches in this model, but online info noted that one of the three might feel "soft" (in my case, one switch clicked in a rather "jiggly" way, the other two were strong decisive clicks.) To access the door switches on
... Read more this model was the only difficult part. First use a torx bit to remove the two torx screws below the latches inside the microwave. This frees the latching part inside, that holds the door switches, which you will remove after you take off the control panel. The top grill has to come off before you can remove the door panel. Remove the screws above the grill, on the microwave top cover, The grill on this model is covered with a panel that moves out when it vents. After removing the two top screws, the covered grill vent slides left to remove. Be careful, as the sliding tabs are plastic. Wiggle and jiggle it, to slip it off. Below the removed grill, is a small metal grill with one screw in lower center. Remove that screw, and wiggle that out. You'll then see the one screw that holds on the control panel. Remove this screw, and lift the control panel up to remove. Again, go slowly and gently, as the bottom tabs holding the control panel in, are also plastic and easily broken. Lay the control panel on something, (I used the coffee maker) and pull out the wire bundles tucked on the left, that are attached to the latching panel. Wiggle the latching panel gently to lift it up off of it's plastic tabs and pull it out towards you, so you can see the three door switches. Each switch (part number WB24X829) has a little black switch on it. Feel each switch with either your finger, or a screwdriver to see which one doesn't "click" strongly. The weak one is the one you will replace. The door switches are fitted into a tab, and plugged into their wires. Remove the defective switch, pull out the wires, and replace it with the new switch, plugging back the wires, and slipping it back into it's plastic tabs. Then put everything back together in reverse order. The entire job took me fifteen minutes EXCEPT for figuring out how to slide off the upper grill, which I have told you. A repairman would have cost $150, the part was $18. AND, there's a good chance, the other two switches will get "used up" in the next year or so as well, so I'll be ready next time. Thank you, Partselect, why work all day, to make money, only to give it to somebody else, for fifteen minutes of work. All I needed was the knowledge.
