After waiting three days for somebody to talk "to their manager", they
have agreed to install a new glass top. I pay the installation $80,
which I'm told is "labor at cost". The switch--the initial reason for
the call--will be another $325 to replace.

What the hell, I'll pay the $80 to get my cooktop back. Y'all have
generally spooked me off the gas stove; the rationale being the heat in
an air-conditioned home, and the fact that I'd have to replace the vent
which has a troubled motor and hasn't been run in 10 years.

Many thanks for the input and the all the entertaining side-fights.
