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 illumi‐
nate 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 Cur‐
tain Switch contacts. Relay 3 will then be de‐energized 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.
