our 29 year old GE JET110 microwave oven finally had a problem.
fuse blown. checked all transformer windings, cap, diode,
magnetron filament. found triac separated from heat sink.

triac tested good electrically, so mechanically re-attached
triac to heat sink (don't ask me how!), replaced fuse, oven
works.

would like to replace triac but cannot find cross reference
for 27X5072. ANY SUGGESTIONS?

A small C-clamp will hold it in place. If it works, leave well enuf
alone. A new microwave would be in order once this one dies, it
doesn't owe you anything. Also, a new machine would probably have a
turntable and many other features that aren't on your old oven.. I am
all for conservation, so if it is working, why not leave the present
triac in?
