2022 - Micro Minnie 2100BH slide fault code

[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?

Have you cleaned the other half of a 12V circuit, the ground half?

I have searched/investigated the ground.
It is in the junction box under the trailer if I am correct?
It was non-coroded/very clean.

Have you tried calling Lippert customer service? I've had good success with them and it is, after all, their system.
Just fyi they also have an "Owners School" which provided great info and hands on for exactly this reason.
Good luck
