i had looked many times for a part number, never found till last week on a 1989 300te,tried internet and local masters supply,no luck with the try.
i been searching the net today for darlington units that might match,we need for some of the electronic folka to step in here and solve the problem,am trying to solve this one because of the waste.
also there has to be a resulting error from maintenance,got a theory that the thermo conductor paste use for transfering the heat from the collector metal plate to heat sink could be drying out and causing the solid state output to over heat and open up.
the fan brushes have to wear out but the solid state power output should last.
come on folks
