Seeking a replacement for a 3-terminal "light delay" component for my
ancient Overhead Door model 100 garage door opener (or something I can
work with to replace the original component) .

This component is ceramic element wrapped with fragile nichrome that's
supposed to heat up a nearby bimetal contact that closes and lights the
lamps for a while after the moter reaches its limit.

The factory stopped making this model and the component back in 82 so
if anyone has an old one they'd sell the part from, or can suggest an
alternative to a new garage door operator, please let me know.
Thanks!


This just occurred to me. How about using a cheap ultrasonic motion
detector switch to turn on the regular garage lights when it sees the
door move? They turn off after an adjustable delay. Our office has them
in the common area johns and they flick on as soon as you push the door
in a few inches.

They also remind you that you've sat on the pot long enough reading and
it's time to get back to work; The lights go out and you have to wave
your arms around above the stall door to get them on again. G
