Lg model lfc23760sw stopped working. The power went out, just stopped working. Would it likely be the power supply?

http://www.lg.com/us/support-product/lg-LFC23760SW Download the manual and look on page 20

and ice maker is making noise and was never hooked up

Needs either a defrost thermostat, heater or timer. Fan hitting frost is the noise.

Assuming you really meant LFC23760SW, you can download the manual at

You likely have a blown fuse on your Master Control Board, this problem has various solutions posted on this site. Look for LFC23760 problems on this site.

I am having the same problem with the same model :(

Unplug fridge.
Open panel on back of fridge (the one at hip height that says Service Panel Only - Do Not Remove, blah blah blah)

Replace fuse with 9A 250V slow-burn fuse. I used a gray fuse harness from Radio Shack so that if the fuse needs to be replaced again I can just pop in a new one without doing the soldering over.
I nuked the original fuse, the end-caps and the wires that went from the end-caps/fuse to the motherboard. I replace those wires with some I scavenged off a fresh thermal fuse (also bought at RS, just needed the wires themselves which seemed to be the same diameter/gauge as the original leads) and ran them from the motherboard to the wire harness.
So far, so good!
Good luck to you.

Unplug the unit and remove the board cover. The fuses are soldered in but can be changed with a soldering iron. They are glass and easily spotted on the board.

Ours went after 15 months. LG didn't want to hear about it.

Replace fuse and two weeks later the fridge stopped cooling (though freezer still works).

Complete sham. Sorry to say, but all looks, no performance. Garbage company with garbage 1/2-cooked products from phones to fridges.

I have the same issue - along with ALOT of other people I've seen posting on the internet. Even though it's a 20 cent fuse, you have to replace the ENTIRE $200 control board. I say this is a defect (intentional?) built in to happen exactly 13 months after purchase.
