[K] Bin Control Switch (Auxiliary Code: D-0 Or Earlier); [L] Bin Control Switch (Auxiliary Code: D-1 Or Later) - Hoshizaki FM-300AKE-HC Service Manual

[k] BIN CONTROL SWITCH (Auxiliary code: D-0 or earlier)

The bin control switch is composed of a
proximity switch and actuator. When the
chute fills up, ice will push up the actuator
on top of the chute to switch off the
proximity switch. After 7 seconds, the
controller board will stop the gear motor
and compressor at the same time. When
ice is used, the actuator will return to the
original position to switch on the proximity
switch. The gear motor will restart in 7
seconds, and the compressor in 5 minutes.
When the bin control switch seems to have
malfunctioned, check the dimensions of the
actuator as well as the operation of the
proximity switch. Also, if the chute switch or
the gear motor circuit protector has
operated for some unidentified reason, be
sure to check the actuator for proper
dimensions.
1) Remove the bin control switch from the
chute.
2) Move the actuator to the maximum
operation angle as shown below (top).
Check that the actuator is about 13 mm
away from the barrier. If not, replace the
whole bin control switch assembly.

[l] BIN CONTROL SWITCH (Auxiliary code: D-1 or later)

The bin control switch is composed of a reed switch attached to the spout and an actuator
(ice detector) provided inside the spout and chute.
The bin control switch operates as follows:
1. Ice reaches up to the ice detector.
2. Ice pushes and moves the ice detector.
3. The actuator magnet shifts and departs from the reed switch
4. The reed switch turns off.
5. The icemaking operation stops.
Heavy soil inside the spout or chute may cause ice to get stuck. Dirty actuator hinge may
disturb the movement of actuator. Check the cleanness of spout, chute, and actuator at
periodic inspection or periodic part replacement. Wipe clean any notably dirty part.
