On a LG model LFC23760st refrigerator with a #AP4501410 control board this is suspicious of being bad, exactly where on the board do I check for incoming voltage to confirm the board is bad ???
There is a connector that has a fuse above it. This connection should tell at the bottom what connections it is. It should say L1 and N and when you locate these 2 connections then that is your point of testing for 120 vac to the control board.
I am replacing the main control board with a new one. There appears to be a reset button on the board. Do I push it after installing the board or not. Thank you
Answer Hello Debby,
The reset is usually only used when the unit has been in the diagnostic mode. The unit can also be reset by unplugging the unit for 3 minutes and re-connecting it to power. The reset button should not have to be pressed upon installation of a new board.
