Fixing the GE Opal 2 by replacing the motherboard

Hi all,

I've had my fair share of issues with my GE opal screaming and squealing
After a long time of experimenting, I've come to the conclusion that the logic on GE's board is inherently flawed.

It doesnt seem to adequately detect the motor being stressed.

So, well, I set out to replace it.

I have a prototype mostly ready. Its making ice, watching the motor current, and managing the pump properly.

I also additionally challenged myself to use all the original connectors.

No wire snipping, no soldering.

The idea is down the line perhaps sell a drop in PCB that will just work out of the box

I've attached the schematic, and here is the github repo for anyone interested.

It has a few things in it, I mapped out all the piping and water flow, some reverse engineering, and the code for my prototype is in /firmware

Curious if people would actually be interested in buying a board should it ever make it to that stage
