[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 not clean and blocks 
infrared rays, the sensor falsely detects the bin is full and stops the unit. When making 
periodic inspections or replacing periodic replacement parts, check that the infrared ray 
passages and infrared sensor lenses in the plastic part of the bin control switch are clean. If 
not, wipe them clean with a soft cloth.
