Hi Kevin;
If it is a K3"S" there is a trace on the bottom of the board that burns 
before T4 cooks. A simple jumper will fix.
If K3, then T4 is probably cooked. There is also a loop of insulated 
wire that goes up and over and down thru T4.(awkward, but probably OK).
Take the top cover off, you can look down there next to the KAT3 or 
KANT3 board to asses.
We have some T4s in the Tech-parts area, when you order, you may need to 
tell them to look there.
Our # is E690126
