Default Update to: What could have done this to my vinyl siding?

There are no heat sources behind that wall besides a toaster oven that sits
on the counter top and is seldom used. I would think any heat source from
inside would have caused some damage to the cabinet directly above. This is
new housing so the walls are insulated.

I haven't used any chemicals on the deck since the spring of '06.

Update:

I got the siding off (hey, it's been raining around here).

All the electrical wiring and connections look sound and unblemished.

The switch for the outside light is a different circuit, but that outside
outlet is hooked to the kitchen circuit too.

Should I cut a 16" X 8" hole in the sheathing?


The first shows definitely the heating shrunk the Tyvek and melted some
of it at the hottest point (which is where I thought it looked like the
center was previously). Can't tell through that tiny little spot what
the actual sheathing looks like.

Definitely need to cut the Tyvek and look under it to tell for sure what
it actually looks like.

Not at all surprising the wiring at the outlets looks ok, they're
removed from where the problem is visible altho certainly if they had
shown something that would have been indicative.

I don't think this has any chance of being lightning, it's more
indicative of a radiant heat source imo and lightning would have really
charred something in all likelihood.

I kinda' like Smitty's WAG -- didn't have a hanging mobile or something
at some point by any chance? Don't know orientation wrt sun, but one
thing the wife does that could be a problem if set in the wrong spot is
brewing "sun tea" in the big gallon glass jar -- put that thing on a
table outside the patio door and it would work really nice as he suggests...

I'd still explore more around that area under the Tyvek and if that
didn't satisfy me, it can't hurt to make the entry hole...

It should be possible to see if the charring (if any) is surface and
improves from the outside in or intensifies once there's an area to look
at in comparison to the surrounding area under the Tyvek, though.
