This shows the heat shield removed. It is probably not necessary to do so, but it is easy and probably makes things a little easier.

This shows the replacement sensor already installed

There is a thin flange at the end of the main body, all around the oval opening, that is glued into the grey/silver outside trim. The photo of the black unit shows this step having been performed by deliberately slicing the thin flange through, at the edge of the grey/silver trim. The other side of the trim has features that align it to the main body, so if you do it this way, it is possible to glue everything back together without any sign of disassembly. But, it probably won't be as strong. The photos of the white unit show a cutter being used to slice the glue, in order to preserve the main body flange. You may find that you have to damage the trim this way, but will preserve the ability to glue it back in place in exactly the same way it was to begin with.

The first instruction notes that no disassembly is necessary (not even up to the second step). The rest is provided to show how this conclusion was reached, and in case others are interested in how it's put together or want to disassemble for other reasons.

For this step, I reheated the screen with the iopener before applying force to set the adhesive.

Readers looking for temperature advice might check the comments of the previous instruction, as there are more there. I used an immersion bath to heat this to 180F and applied it to the device until the outside temperature of the opener read 150F with an IR thermometer. Removing the screen took very little force with this method. I don’t know how much microwaves vary in heating consistency with these pads, but knowing how inconsistent the temperature of a bowl of plain rice gets in my microwave, I wasn’t interested in even trying to use it for this.
