Harvest Assist Assem Bly / Hot Gas Valve - Ice-O-Matic CIM0320 Technical & Service Manual

ELEVATION SERIES CIM CUBER
Harvest Assist Assembly/Hot Gas
Valve
Operation
The Harvest Assist Assembly is mounted to
the back of the Evaporator Assembly. It is
energized by Relay 3 along with the Hot Gas
Valve. As the unit enters the Harvest Cycle,
Relay 3 will illuminate indicating voltage is
being sent to the Harvest Assist Assembly and
the probe will be pushed forward to meet the
ice slab.As the Evaporator warms, the Probe
on the Harvest Assist will move forward to
help release the ice from the plate. As the ice
slab falls it will open the Magnetic Curtain
Switch contacts. Relay 3 will then be de‐ener‐
gized and the Harvest Assist will automatically
return to the starting position.
Troubleshooting
The Harvest Assist Assembly is energized with the Hot Gas Valve throughout the Defrost Cycle by
Relay 3. To quickly verify operation, put the unit into Diagnostics program by pressing both the
Power and Wash buttons for 6 seconds, then quick press BOTH the Power and Clean buttons
until the Harvest Cycle is initiated (R2 ‐ R6 LED's above component Molex should illuminate).
Verify LED for Relay 3 is illuminated and check voltage between the Blue and Red wires at Molex.
If no voltage is present, the Board or Molex may be the issue. If voltage is verified, Check for
voltage at the wiring connector for the Harvest Assist. If voltage is verified and the probe is not
pushed forward, the issue is the Harvest Assist.
