The Kenmore Ice maker makes no ice. This is a side by side unit. The freezer is very cold. The water solenoid is not faulty, but is not turning on so the problem must be in the electronic ice level detection boards or the wiring to the solenoid. (The water in the door works fine... so I tested the ice water supply solenoid using the water in the door control... and the ice solenoid turned on when the water in the door dispensor lever was activated)... The LED light on the ice maker comes on when the door is opened. But with all door switches closed as if the door were closed, no water is coming into the ice maker. The water solenoid id not being energized. Is there a method to trouble shoot the two electronic boards that detect the ice in the bin? (without replacing both boards?) One board is simply an LED that should 'shine' into the photo transistor of the opposite electronic board through the ice bin. There is no visible light being emitted from the left LED board. The right board has a power LED that comes on for a short tme when the door is opened. Do I need to order both boards to determine which is bad? We shined a red LED pointer beam into the receiving photo transistor hole without any change. The refridgerator was purchased in 2004 and is beyond the warranty period. The temperature controls are both set at '4' which is the recommended mid range. Other than no ice, the refridgerator works perfectly. Is there an ice water filter that may be frozen? but we cannot hear or feel the solenoid energizing for the ice like we can for water-in-the-door solenoid. Thank You in advance for any help you may give, including after market parts suppliers. Monte Wilke
