Customer Questions and Answers for Refrigerator Temperature Sensor Assembly by Lg

Allan, it is recommended that the control is tested at connection CON6. On the left side of the connector is a yellow and black wire, a blue wire, and a grey wire next to each other. With the black probe of a meter on the grey wire and the red probe on the blue wire, there should be a DC voltage measurement of 12VDC. If not, then the main control CSP30021077 is faulty (same as when testing the freezer fan motor). If there is 12VDC, then the red probe will need to be moved to the yellow and black wire and if it reads 0VDC or 5VDC, then the RF fan motor EAU65089701 needs to be replaced. The FZ fan would be tested at CON7 and the 4th, 5th, and 6th wires from the left at the bottom of the connector would be tested. The black probe of the meter will be placed at the 6th wire and the red probe at the 5th and it should measure 12VDC. Then the red probe would be moved to the 4th wire and if it measures 0VDC or 5VDC, the FZ fan motor EAU61524007 would need to be changed out.
