Our refrigerator is 5 1/2 years old. Last night I noticed the light would not turn off on the outside, This morning when I went to get ice water came out instead, hit the cubed button again and the ice came out. At dinner went for ice and nothing. No lights on for water, crushed ice, cubed ice nor does the light for when you put a glass underneath come on. Tried switching the breaker to restart the fridge. Nothing! Left it turned off for about 10 minutes hoping it would restart it, again, nothing. Anyone have any suggestions on what can be wrong, how to fix it?
