DIAGNOSING AN ICE MACHINE HEAD SECTION 

THAT WILL NOT RUN

If the water pump is energized but no ice is produced,

refer to “Diagnosing a Condensing Unit that Will Not

Run.”

1. Verify primary voltage is supplied to ice machine

head section and the fuse/circuit breaker is closed.

2. Verify control board fuse is okay. If the bin switch or

water level probe light functions, the fuse is okay.

3. Verify all bin switches function properly. A defective

bin switch can falsely indicate a full bin of ice.

4. Verify ICE/OFF/CLEAN toggle switch functions

properly. A defective toggle switch may keep the

ice machine in the OFF mode.

5. Verify low DC voltage is properly grounded. Loose

DC wire connections may intermittently stop the ice

machine.

6. Replace the control board.

Be sure steps 1-5 were followed thoroughly.

Intermittent problems are not usually related to the

control board.

Warning

High (line) voltage is applied to the control board at

all times. Removing control board fuse or moving the

toggle switch to OFF will not remove the power

supplied to the control board.
