All Installation Instructions for Kenmore Microwave 40180086700

Microwave door did not close

Initially I called a Samsung recommended appliance repair outfit to fix the latch. The technician informed me that he does not fix latches. I need to buy a full new door for the microwave for $215 plus he charges $165 to come to my house. I got angry and did some research and it turned out that this is a very common problem. I ordered part PS4229162 "door key" $6.67 then followed the instructions on a youtube video by zimsjeep
"Repair a Broken Microwave Door Latch" to install. At first I struggled a bit hooking up the spring to the frame, but then I used a slim plier to hold the spring (instead of my fingers) and that did the trick.

Buzzing noise, no heating of food

Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.

Appears to work, but food not heated

The high voltage tired was shorted. I replaced it with a new one, but that did not solve the problem.

You can test the high voltage tired with a voltmeter and a 9 V battery. Search Search for it on YouTube.

You can also test the high voltage capacitor, the high-voltage transformer, and the magnetron with a multi meter. Search for the procedures on YouTube.

I tested all these high-voltage components with a low-voltage multi meter, and they all checked out OK (after replacing the diode). However the microwave still did not heat food.

When working on a microwave it is important to unplug it and also discharge the high voltage capacitor. The capacitor has a 10 megaohm resister to automatically discharge itself, but it may have failed – – so discharge it manually.

In the end I ordered a new microwave.

Microwave would continue to run even when door was open. (even if no time was left on timer)

Unplugged Microwave, Removed vent cover (2 screws on top of microwave, then slide cover to the left, then forward) Removed control panel (1 screw at top of panel) then removed the two screws that hold in the door switch assembly. (these you will only see by opening the microwave). Located lower door switch, removed connecting wires, and pulled switch by releasing small plastic tab which held it in. Put new switch in place, reconnected wires, then reconnected door switch assembly. Reconnected control panel, and then put the vent cover back on. Tested microwave and it no longer runs when the door is open. Super easy fix, and was done in under 5 minutes.

Microwave would keep running when door was open

Searched for a YouTube video that included “replace Samsung microwave body latch” (whatever part name). There are plenty of easy how-tos.

Can't Install Broken Parts

This is the second time that I received the same part broken because of poor packaging at the factory. When I spoke with customer service after the first one arrived in pieces I suggested that they advise the shipping department to change how they ship delicate parts. Nothing changed. Same result.

Microwave stopped working - would not heat up

I removed the outer cover and exposed the inner workings. I watched a video on partselect.com to show how to remove and replace the Diode. I followed the instructions and it was very easy to replace.

Unfortunately, the diode was only part of the issue. I ended up replacing the High Voltage capacitor and Magnetron also. Those were a little more complicated but still easy to do.

Now the Microwave works just like new! Cost me less than $100 for all parts.

CANNOT INTALL A BROKEN PART

I ORDERED THIS PART AND IT CAME SEVERAL DAYS LATER AND IT WAS BROKEN. I SENT IT BACK WITH A BIG NOT SAYING A REPLACEMENT PART MUST BE IN A BOX FOR SHIPPING. THE SECOND PART CAME, NO BOX, AND IT WAS BROKEN. SO AFTER THREE WEEKS PLUS IT IS IMPOSSIBLE TO DO ANY INSTALLATION. I THINK THE SHIPPING DEPARTMENT IS BROKEN AND NEEDS SOME HELP.

The plastic door key (latch) broke where the spring attaches.

I took off the inner plastic frame of the door, removed the broken part, hooked the spring up to the new latch and replaced it into the proper alignment holes, and works perfectly. It was less than a 5 minute repair.
