- K chute bin control switch fm 750 1000 auxiliary code a 2 or earlier fm 1200 1800 auxiliary code a 3 or earlier the chute and bin control switch are caulked and combined ice formed in the evaporator casing passes through the spout chute and bin control switch and drops out of the unit bottom the chute is made of integrally molded hard pvc and soft pvc ice sliding down on the spout hits the soft material resulting in lower hitting sounds the bin control switch is an infrared photo sensor built in a plastic bracket the infrared photo sensor has a light emitting element and a light receiving element the sensor detects there is no ice when infrared rays from the light emitting element come into the light receiving element when ice comes between the two elements the sensor detects the bin is full and stops icemaking operation the unit resumes operation automatically when ice disappears from between the two elements if the plastic part of the bin control switch or the infrared sensor lens is 101
- The ice detector is different for flake icemaker and nugget icemaker if incorrect detector is attached the bin control function will not work if the icemaking operation continues the abnormal stop switch trips and the unit stops with an error be sure to attach the proper ice detector the actuator is composed of two components bonded the letters c and f are stamped on the fitting part the type of icemaker can be distinguished by boss fitting position 103
