Panasonic NN-TK922SS 27-inch Trim Kit for 2.2 cu ft Microwave Ovens, 27 inch, Stainless Steel

I had to make some adjustments to get the microwave and trim kit to fit the space vacated by our old, broken microwave. The previous space was smaller than the specs required for this trim kit. The solution was MAGNETS, and it worked fantastic! This solution could probably even be used over the standard installation as it allows plenty of wiggle room for positioning the trim frame.I placed the new microwave directly on the shelf and did not need the metal riser. I installed a metal corner bracket to the shelf in back to help position the microwave depth-wise in the opening and attached the left duct as recommended. I installed 3 in. metal ties to the outside of the cupboard inside of where I wanted the corners of the trim frame. Instead of using the mounting hardware provided, I purchased four magnets from the Home Depot (2 x 2-packs of 3/8 in. x 1/2 x 1-7/8 in. Heavy-Duty Block Magnet, $8 each) Note, the dimensions and strength of the magnets are important. I had to include a spacer as there is a bump on the inside of the trim kit frame that prevents the magnet from lying flat - I cut pieces from a paint stick and it was just the right width to make the magnets flush up to the metal ties when positioning the frame. See photos for the assembly (they unfortunately did not post in the right order).

I give 5 stars for the finished product. But the instructions were sketchy and the installation was a challenge. This trim kit is designed to fit the Panasonic NN-SN9665 microwave. Be SURE you match the right serial numbers of the microwave and the trim kit - a number of customers complained about mismatches. My biggest complaint is the pathetic attempt to save a buck by having the customer bend a flat piece of sheet metal into the shape of a vent and attach it to the oven. The bend lines are identified by perforations but you can easily bend them the wrong way, creating a vent that doesn’t fit! Yep, I did that and had to rebend the thing into the right shape hoping it wouldn’t break because the 180-degree stress. Then you are instructed to tape…yes tape the flanges of the vent to the microwave! No tape provided, so I tried electrical tape which I could see was inadequate so then used strapping tape. Conquered. But we’re not done with this vent yet. As we (it took two of us) tried to plug in and get the unit into the cabinet opening (exactly 27”x17-3/8” as instructed) that dad gum vent got in the way! Fortunately the interior space was bigger than the cut-out opening so we were able to wedge the left side of the unit to get it in and onto the kit platform. Another half inch added to the height dimension would be tempting, but then the corner brackets wouldn’t fit right for the trim piece! I recommend bending that vent flatter. It’s just taped anyway with one screw in the back. Final look - fantastic! Matches our gas oven perfectly. I suppose that vent does it’s job but I hope the engineers would do a better job on new iterations of that stupid vent! We have a much larger cavity than the opening and I was tempted to leave it off - it probably would have been fine. But a tight fit could be a problem with heat and moisture. All said it looks great!

This is a VERY expensive piece of trim, that leaves quite a bit of space around the microwave and uses plastic clips to hold to the cabinetry. Because of this, there is almost no flexibility on the install, and you need to make absolutely sure your cabinet is to the letter to use it.Because this microwave was replacing an older microwave, while the new microwave was nearly exactly the same size as the old one, the cabinet needed to be almost 2 inches wider JUST because of the trim piece.Unlike some older trim kits there is nothing that is screwed into your microwave- the feet nest into the metal tray you put into the cabinet- so we'll see how it holds up. For being almost as expensive as the microwave, it was surprisingly janky. Make absolutely sure you have the right trim piece for your microwave and the correct size for your cabinet or you will be in for an unpleasant day.While it looks okay once in, the cost for value, difficult to understand instructions, and very large cabinet relative to the microwave this requires are all good reasons to give this (and the microwave it fits!) a pass if you can find something else.
