LGHC2342LF2 Frigidaire Wiring Diagram Help

[Jabrams]

Checking http://manuals.frigidaire.com/prodinfo_pdf/Anderson/240389641.pdf

4 Wires from the Ice & Water Module run through the door harness. IIRC wires 1 and 2, BRN/BLK and BRN/BLU should be 12V DC and GND, a 12V relay that operates a 120V AC circuit.

However, I am reading 120V AC on both wires. 

These two wires trace back to the main control module. 

So, can I safely conclude that the main control module is bad?

Secondly, since 120V AC is running to the 12V DC relay on the Dispenser Control Module, can I safely conclude that the Dispenser Control Module is bad too?

Thanks for any help.

Hard to tell about voltage reading you gave. Need to know what points you are measuring.  The schematic is poorly labeled when they use GRD for the low voltage supply.  It is not chassis ground or ac ground. When taking DC voltage measurements you must use this "GRD" not the cabinet frame to get correct voltage readings.   Usually  when AC and DC supplies mix there is smoke involved. 

What is your issue with the fridge? Will make helping you easier if we know what to troubleshoot.

Thanks again for helping.

The auger motor does not operate when the dispenser lever is pushed.

I took out the auger motor and tested it and it works fine. 

The ice & water module will dispense water, and all the lights appear to work correctly.

But the auger and the ice chute flapper won't operate. 

The freezer door light switch operates normally.

 

My thinking was the relay in the Ice & water module was bad. So I started by checking the wires in the door harness that go to the relay and I found the wires that should be 12V DC showing 120V AC. The fridge was like this when we moved in, so if there was smoke at some point I might have missed it.
