Hi,
I have the same model refrigerator GC55HGXKB00, the same thing just happened to us, The water, ice and the light does not work on the
dispenser panel in the front door. It is still making ice. Also the water
filter was plugged for a while, so we replaced that and now it looks like
it might be leaking underneath. We can't tell yet for sure or if a lot of
water shot out under the frige when we replaced it. I have wood floors
so we are worried. We took off the back panel and front as well, we
can't see anything leaking. We then took out the the water filter
for now. How do we get a control board and what about the water
under the frige. |
