I have a roughly 2 year old LG d/w (LDF7932
) which just up and lost all power right after running a cycle. I have 120V coming in but pressing the power button yeilds NOTHING (or any other button), no LEDs will power on. The diagnosis flowchart states that after checking the circuit breaker, check "The power switch or the circuit is OK? Check Controller (Power Circuit)."
I have pulled the front of the d/w off and the PCBs are easily available, however I cannot find any diagrams labeling what is what. The diagram shows 3 PCBs - Main, Cycle and Option/Display. I am assuming the largest one just below the button "bar" is the main PCB.
I need to determine the correct failed part so that LG will send me a replacement. But the diagrams are not really helping me and the flowchart doesn't tell me how/what to check for "controller (power circuit)".
Can anybody assist me?
