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?
