C. Control Board

• A Hoshizaki exclusive solid-state control board is employed in KM-1301SAH/3,

KM-1301SWH/3, and KM-1301SRH/3, Stackable Crescent Cubers.

• All models are pretested and factory set.

CAUTION

1. The control board is fragile; handle very carefully.

. 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.

4. Do not change wiring and connections. Do not misconnect K3, K4, and K5,

because the same connector is used for the thermistor, K4 jumper, and oat

switch. The control board RED K4 connector must have the K4 jumper in

place for proper operation.

5. Always replace the whole control board assembly if it goes bad.

6. Do not short out power supply to test for voltage.
