40185059210 Kenmore Microwave - Instructions

The repair was very easy, however the bulb was not the same as the original one. The original bulb had a bright setting and a low setting, but the replacement bulb was only the low setting bulb. There was no bright and dim operation. The switch on the microwave had the duel settings.

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.

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.

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.

By removing one phillips headed screw, a metal frame pivoted down for easy replacement of glass plate.

The part should have just been pulled up and out, mine was broke off so I had to drop the bottom tray and push the remaining old coupler up and out. I dropped the new part in and reinstalled the bottom tray. It was also a good time to clean the tray

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

Part arrived on March 15. When I went to install it on March 16 I found that it was the wrong size. On the same day I emailed PartSelect of the problem. They responded via email the same day and advised that the correct filter had be located and was being shipped. In addition, a separate e-mail had shipping instructions and an address label. On March 18 the part was returned and presently I am awaiting the replacement part. Todate I am well pleased with PartSelect's responsiveness and handling of the matter.

Got the part and replaced it. Simple. Pleasure to work with

Opened light panel and replaced bulb. Very, very easy.

I am concerned, however, that this bulb does not emit the same amount of light as the one i replaced. The item number is the same, however, so I am perplexed at this bulb efficiency.

With microwave still attached under the cabinets, I removed 2 screws for the top grill and then one screw for the bulb cover plate. This provided access to the bulb. The replacement bulb was a simple plug-in.

The best part of this experience was the exploded parts diagram on the PartsSelect web site which allowed me to easily locate and order the correct part.

I followed the instructions in the owners' manual on how to access the bulb. Installation was a breeze. I couldn't believe how fast I received the replacement bulb from PartSelect. I ordered it on line one afternoon and Fedex delivered it to my front door before 9:00 A.M. the next day. Awesome service.

REPLACED DOOR SWITCH ASSEMLY

Ordered (most difficult part of repair, because I wasn't sure the one I ordered would fit), opened box, removed padding, opened microwave oven door, lined up center indentations with center and my repair was complete. Placed a cup of lukewarm coffee on the tray, closed door and pushed auto 30 seconds. The cup went round and round on the plate that went round and round and then, the END chime sounded. Success! Lukewarm coffee has been transformed to HOT coffee on the newly installed cooking tray.

I unscrewed one screw and droped the glass light bulb cover, bent the light bulb up so it wouldn't break the glass again, removed the broken glass and installed new glass by bending the tabs over the glass to hold it in place and re-inserted the cover, then screwed the retaining screw back in. Done in 3 min.. PartsSelect.com seems to be one of the few online parts ordering place that has schematics and easy to navigate site. Perfecto!
