Product review (5 stars): Pleased with purchase
Installed on Kenmore branded whirlpool refrigerator. Symptom was slow to no ice production. Purchased thermometers first to check temperature which was fine. Dropped first ice about 10 minutes after installation. Installed a couple of weeks ago and has been working great, the ice bin is full. The original broken optics board was blinking twice, once second pause, repeat with no change blocking/unblocking the sensor. The original board would still make ice intermittently / erratically, though not enough to keep us in ice and we'd run out.
