Yes, it is a legitimate concern. Normally a recessed fixture is
fastened from the bottom. Are you missing retaining clips by any
chance?

R- Hide quoted text -

The cooktop edges rest OK on the countertop, so it is being held up by
the countertop without any clips or screws at all, but it slides
around a lot. The cooktop kit says to install four wood screws (not
included) all around the each side of the cooktop to keep it in place
where you want it.

Then they tell you to install the retaining clips included in the
"cooktop package," which screw into the bottom of the counter top and
hook into the bottom of the cooking unit.But the instructions
say....and I need to also, put in the woodscrews first.

Here's the text from the instructions:

Set the cooktop into the countertop cutout.
NOTE: Do not use caulking compound;

Models: 26" and 36" (36"X18") Coil Elements
Cooktops
Set the cooktop into the contertop cutout. Lift the
cooktop and fasten the ends of the box to the counter
with wood screws (figure 11). Lower the cooktop.
Align the knobs on the shafts and press down with
even pressure. After setting the unit into the opening,
all remaining work must be done from inside the
cabinet.

And, a link to the PDF with the manual (Page 5 is the relevant page,
and it's Step #2 (26" and 36" coil elements cooktops):ftp://ftp.electrolux-na.com/ProdInfo.../318201410.pdf

Those screws do very little work. Basically they're there to keep the
thing from sliding around while you fasten the retaining clips. Use
small screws and drill pilot holes and you'll be fine.
