I've got a Kenmore fridge, model # 596.58692890. It's a side by side with water and ice in the door. It's got a light sensor on the dispensing area that makes the little light in water/ice area come on 50% power or so when it's dark (aka light sensing night light). The problem is that the night light no longer functions. When you press the lever to get water or ice, the light comes on like normal so I know the buld is good. I'm wondering if anybody has any testing info that I could get to test and see if I've got a bad sensor or if there's something else going on. Thanks in advance guys/gals.
