These glass cooktopw are very fragile. This is the third replacement. There is very little clearance between the dropin basic, rectangular metal box that holds the elements, switches, electric cable. The cooktop is mounted on that metal box with twelve (12) small sheet metal screws. Once the entire box with cooktop is CAREFULLY lifted out of counter top. Use a 1/4" socket to remove all twelve screws then lift off the old cooktop. No problems up to this point. The new cooktop comes with the same angle brackets with matching screw holes. Replace all twelve screws. There are rubber grommets for each of five, in this case, controls to keep any spills from seeping into the basic element box. Extracting and replacing these is somewhat ackward.
So far so good. Now you must carefully balance and lift the whole stove box with attached cooktop and EASE it back into the countertop. Big problems here. In my case the replacement top was about 1/8" too deep. When trying carefully to return it into its hole. It was off just enough to crack the new cooktop when returning it.
PartsSelect agent, Triva, was very helpful and understanding and shipped a second cooktop in short order. Very unfortunately this one was shipped in a less secure shipping box. It was already broken in shipping. PartSelect was once again most helpful and promptly shipped another replacement. It arrived well shipped and in perfect shape.
While waiting for its arrival, I attempted to elongate the counter top hole to accomodate the 1/8" deeprt cooktop. VERY difficult inasmuch as the countertop (sorry about the continuous 'countertop' vs. 'cooktop' word usage)...
countertop is Marble.
After a few cuss words I got some little elongation...still not enough. The re-topped stove box fit better. But, the electric fumes hood, in back, side to side, (the worst place for the 1/8" too deep cooktop), was too tight to go up and down. It is a dicey operation. Next to impossible for the average DIY-er. With a rubber hammer, some shims, some rubber bumpers and a lot of sweat it now works but not as smoothly as with the original cooktop.
PartSelect was most helpful and patient. It is NOT at all their fault the the replacement cooktops are so minisculy bigger. It is a manufacturing tolerence. My original cooktop from 1992 was somehow just enough smaller that is fit though without ANY tolerence.
In summary. This is a job for a very capable, patient, and DIY-skilled man, as well as somewhat robust. I have all of that and more yet this became a difficult installation. PartSelect prices were very reasonable and the labor costs I saved compensated for my difficulties. It is not for the faint hearted.
