Diagnosing An Ice Machine That Will Not Run - Manitowoc Neo Technician's Handbook

Diagnosing an Ice Machine
that Will Not Run
High (line) voltage is applied to the control board
at all times. Removing the control board fuse or
pressing the power button will not remove the
power supplied to the control board.
1. Verify primary voltage is supplied to ice machine
and the fuse/circuit breaker is closed.
2. Verify control board fuse is okay.
NOTE: If any control board lights are on, the fuse is
okay.
3. Verify the bin switch functions properly. A
defective bin switch can falsely indicate a full bin
of ice.
4. Verify power button functions properly. A defective
power button may keep the ice machine in the
OFF mode. Refer to page 98 touch pad
diagnostics when steps 1-3 test good.
5. Be sure Steps 1 – 4 were followed thoroughly.
Intermittent problems are not usually related to
the control board. Replace control board if touch
pad operation is correct.
