Control Board - Hoshizaki KM-1900SAH Service Manual

C. Control Board
• A Hoshizaki exclusive solid-state control is employed in KM-1900SAH/3,
KM-1900SWH/3, and KM-1900SRH/3 Stackable 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 board.
3. Do not touch the electronic devices on the board or the back of the board to
prevent damage to the board.
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 board assembly if it goes bad.
6. Do not short out power supply to test for voltage.
