Control Board - Hoshizaki KML-351MAH Service Manual

C. Control Board
• A Hoshizaki exclusive solid-state control is employed in KML-351MAH and
KML-351MWH Modular Crescent Cubers.
• All models are pretested and factory-adjusted.
1. Fragile, handle very carefully.
2. The control board contains integrated circuits, which are susceptible to
failure due to static discharge. It is especially important to touch the metal
part of the unit before handling or replacing the control board.
3. Do not touch the electronic devices on the control board or the back of the
control board to prevent damage.
4. Do not change wiring and connections. Do not misconnect K3, K4, and K5,
because the same connector is used for the thermistor and float switch. K4
is not connected.
5. Always replace the whole control board assembly if it goes bad.
6. Do not short out power supply to test for voltage.
