LG wiring Diagram

Refrigerator & Freezer Repair
1

I’m new to this group. Thanks for viewing my question. I have an LG Model LRBN20512WW about 3 years old. Recently moved it and installed the ice maker. Everything worked fine about a week and then the fridge (top) stop cooling. I found that the fan in the back or the freezer blows cold air up to the fridge was not operating. Checked the and there is 120 volts in the pink and blue wires, need to find out what the gray wire is before I replace the fan. Does anyone know where I can get a diagram? Or maybe know whats wrong with it?

TIA
Jamie

There should be a diagram in your unit probably around the compressor in the back, behind the kick plate or in the control panel.

I check there and didn’t see any.

About the only place to get the wiring diagram is straight from LG, but it should have come in the unit. If my contract from LG was completed (in the process) I’d locate one for you.

If the fan isn’t working that’s why the frig portion isn’t cooling it has to have the air from the freezer blown into the frig to cool it.

I suspect its the fan but the the third wire (read my original post) has me thinking the fan might need a signal from something else. If I had a diagram I could see what the extra wire is and check it. I’'l look again tonight for a diagram.
Thanks

whats your model# and does it cool any at all? is there any frost build up in freezer on back evap cover? have you taken the cover off to check frost pattern on coils? is the compressor running? are the fans running?

A friend who used to do appliance repair stopped by last night. He found the white/pink wire bad. It broke off inside the motor. We also have the LBRN20512WW model. I won’t buy anymore LG products. I emailed the company but they never responded back, even though they said they would.

Thanks for your time,
