[TenTec] 253 autotuner stepper motor

[Gary Hendricks]

Has anyone had a failure and found a sub for the stepper motor in the
253 autotuner? It has part number PF-42-48X4 18 ohm and no manuf
stamp.
I removed and disassembled /lubed roller inductor but motor still
stalls at times. I have re-seated all connections on logic board but
motor is intermittent. Voltage levels on logic board seem fine.
Thanks
