Had a weird one today. Got called to go behind another tech. The machine ran fine but would not sense the ice falling. Therefore it would get 2 blinks on the ref light and eventually lock out. The weird part is that the bin full light would go off and on when breaking the eye beam. It just wouldn't sense the ice. The other tech tested the eyes (circuit 4) and all checked good. To make matters worse, the control board and eyes had been replaced a few months prior..........? It now has the blue board. Checked Voltage (line/control) and insured the ground was tight. There did seem to be about a 5 second lag when breaking the eyes to illuminate the bin full light and visa versa.
I have to say, it stumped me. The other tech asked what I found and what he should do. So we are going to try another set of eyes.....(cheaper part) and I think we have a control board at the shop if needed.
So any ideas?
BTW Voltage was 204 on the correct terminal on the transformer and the transformer was putting out 26 volts.
