slide fault code 2022 Micro Minnie 2100BH

[mtneering]

Schwintek/Lippert Dual Motor Synchronus Velocity Slide Controller
Part # 13398-DO

I have a slide controller fault code:
one green blink 9 red blinks - hall power fault to ground....
I have cleaned all the corrosion from the bus bar and the terminals. I also replaced the 20amp auto-reset breaker as it was grossly corroded.

I get clicks in the motor and then reverts back to the fault code.

I then swapped the terminal for motor one and motor two to see if I can get a fault code on motor two---- trying to isolate if it is the motor or wiring harness.

The fault code remained on motor one (one green blink 9 red blinks) after the swap.

Would this indicate a faulty control unit?

Hi mtneering,
It sounds like a bad motor to me:

Very curious about all the corrosion on a two-year old trailer. It almost sounds like salt water got into the motors. I wonder if you could take the motor apart and look for corrosion damage?
