Hi please help...

Fridge: 2006 LG model LFD21860ST, french door style, freezer drawer counter top depth.

Problem: Error code FF displayed.

I accessed the freezer fan. The fan has three leads (purple on left, red middle, black on right). Not knowing which leads to test, I tested all two wire combinations after plugging fridge back in and taping freezer drawer switch closed. I got no voltage readings. Not satisfied this was a valid test, I removed the fan and direct tested it with a 9V battery. I couldn't get any fan rotation with any two wire combinations.

With the error code FF and fan not operating with the 9v bat, I ordered part number 4681jb1027h (fan motor).

Installed fan.

------------------------------???????????????????------------------------------

I'm still getting the error code FF approximatley 90-120 sec after fridge is pluged in???

Is there a temperature sensor?? I didn't see one when I removed the back panel in the freezer drawer. Could this be the problem, a bad sensor and where is it???

Is all this pointing to a bad mother board??

I hate just replacing parts for the sake of it.

What is my next few trouble shooting procedures??

Please help.

Thank you
