icemaker, whirlpool frig, #GD5SHAXMT00

Have voltage, although not as high as at the wall plug, at the black and white wires of the internal ice-maker plug. But, get no voltage reading when probing test points L and N with module pluged in. Accordingly, jupming T and H does not run the motor (or start the cycle). The water inlet valve has been replaced and is operational; the heater test for resistance (L and H) above 32 degrees is within tolerance.
Are there other parts or fuses within the module that may have failed when I left the motor-testing jumper(T and H) in place for too long, which made the metal tray very hot, after replacing the water inlet valve?
Any suggestions, solutions, guideance and (or) comments will be greatly appreciated.

Thanks James
