I have not removed the power module. I"m not sure where it is located. I removed the cover at the left not alot there. Model #795.76204.901 SN 104MREN16484
The icemaker has failed and needs to be replaced. There are no repairs possible on these because no parts are sold for them. I am LG authorized and replace many of these, so there is nothing odd about your situation.
The only screw that gets taken off is the one under it; the whole icemaker then lifts off the supports on the side, so those 2 screws DO NOT get taken off.
I should not have to get billed twice to get that information. WHAT A RIP OFF.
