Parts guy was stumped by the intact filament/no continuity too (see Van's
post). But I decided to try a new bulb (for $11.24.


What is so special about the bulb that they can get that price? You can
probably find it cheaper on the internet but then the S&H would be $10.

Bulb is 25 watt, tubular, about 2 inches tall, integral plastic base with
two blades protruding beneath that slide into female connector.

The filament is circular going around the circumference of the glass and is
supported by 5-6 separate wire posts -- each topped with a loop to
support/lock the filament wire.

The parts people only had a 20 watt, about 1 1/2 inches tall. That's the one
I bought and put into the microwave.

No reason a 79 cent standard appliance bulb couldn't have been designed into
it originally-- but then again, these are the same guys that forced me to
take the entire sheet metal cover off. Good thing I had the right bit to
remove the 6 locking torx screws they used to fasten the case.


It's really ridiculous they way so many products are designed by graduate
engineers using custom/proprietary parts and sub assemblies when standard
parts would do just as well. Adds cost, complexity, assembly errors--- and
no real benefit to the end user.

We sold the old Brown and Sharpe screw machines a few years back, but
made quite a bit of money with them over the years, making (among other
things) custom screws. Nine million stock screws at the hardware store,
and engineers still insist on designing things that need a custom screw.
