Hey guys! I just signed up to this forum after downloading the service manual for the washer I'm working with.
Unfortunately I wasn't able to get the washer to do what I needed it to do via the control board/service mode and ended up blowing the board in the process anyway.
I know this isn't exactly a repair but I'm hoping the pros here can help me still.
What I'm trying to accomplish is hard wiring the motor to spin at full RPM so I can use it as a centrifuge. Its a direct drive motor with only 4 wires (red, blue, yellow, green). I couldn't find a run capacitor anywhere near the motor for the life of me, but I'm wondering if it was built into the board.
So far this is what I've discovered.
4 wires are
Red - power?
Blue - common?
Yellow - signal (130v top spin speed)
Green - ground
I tried connecting the red and yellow wires together, because while I was testing the voltages during the spin cycle the red was constantly at 120v and the yellow ramped up from 0 to 130v. I was hoping I could send power to the motor and initiate a spin at the 120v RPM via the signal wire.
All I got was a hum from the motor.
So what I'm guessing is the run capacitors were built into the board, which is now shot.
My question I suppose is, can I wire in a different run capacitor directly to the hot wire, then to the motor? I've seen a bunch of YouTube videos doing this, but not with an LG direct drive motor. It seems simple but I'm stuck.
Any help is much appreciated!
Thanks in advance
