I have an LG side-by-side frig with no light on the frig side (not the freezer side) and no water from the dispenser. The freezer side has a working light and ice dispenses.

Turn the temp down on the refrigerator side but not below freezing. Some frigs have a "trap" set up for the water dispenser. its located behind a panel in the frig and it is there to help chill the water before it dispenses. if the frig setting is too cold then it can freeze the water .

I can only think of a couple of things to check, 1. if there is a small screen on the end of the water line that delivers water to the refrigerator, it may be plugged, and 2. maybe the filter in the refredgerator it self is plugged.

You have a bad main control board . Located behind the refrig , behind an 8 X 10 " panel . Easily replaceable . Sorry , not Seabreeze . You can reach him at seabreeze appliance parts . com , I think .

1st make sure you got water to the frig.
defrost the frig by turning it off for 2 days with the doors open. Sometime the water freezes inside the door and the water dispenser doesnt work. the turn back on and see if you have water. every 6 months you should change the filter (it could be the problem too)

u might have unpluged something

'After about ten months, the water dispenser stopped. I found a 5/16" coupling below the freezer door. Following the instructions on a tab attached to the hose, I separated the hose from the coupling. I then actuated the water cradle. Water gushed out of the tubing. The dispenser side of the dual water valve is ok.
I snaked a wire into the hose toward the dispenser until it stopped. I withdrew the wire then measured the length. The hose had a blockage at the lower left edge of the dispenser opening. I didn't know if there was a check valve in the hose. Since it was still in warranty (2 months to go), I called service.
I didn't say anything about what I did to the tech. He concluded that the hose was frozen (there is no check valve or anything else in the line between the coupling and the dispenser). According to him my options were to replace the door (he actually said that) or shut down the frig and let it defrost. I fabricated a double layer cardboard cover for the freezer compartment. I removed the light bulb then covered the opening. In about 60 minutes the dispenser started working again. I have had the frig since 12/03. It just froze up for the sixth time today (3/20/07). GE has offered no help or acknowledging that the frig has an insulation problem.'

ACTUATOR SWITCH IS BAD

This water line does not run through the freezer. You have a switch in the door where you get water that activates the water valve in the back of the Ref.

One or both of these are bad and needs to be replaced.

Sounds like to me your filter needs replaced...how long ago have you changed them?

the relay valve that controls the water is stuck.
likely hard water deposits,
