DIAGNOSING AN ICE MACHINE
THAT WILL NOT RUN
1. Verify primary voltage is supplied to ice machine.
2. Verify that the fuse or circuit breaker is closed and
the ice machine is plugged into a receptacle.
3. Verify control board fuse is OK.
4. Verify the transformer is supplying power to the
control board.
• If the interior light functions or the red control
board light is energized the transformer is OK.
• If the transformer is supplying power to the
control board and the red control board light
will not energize, replace the control board.
5. Verify the “Power” switch functions properly.
• If the red control board light is energized and
depressing the “Power” switch does not
energize the green “Power” light, check the
interconnecting wire, then replace the interface
board.
6. Verify the bin thermostat functions properly.
• The green “Power” light will be energized and
the ice machine will function in the “Clean”
cycle when the bin thermostat is open.
7. Check control board light to see if ice machine
shutdown on over temperature limit (control board
light will flash rapidly).
8. Replace the control board.
• Be sure Steps 1-6 were followed thoroughly.
Intermittent problems are not usually related to
the control board.
