C. Control Board
• A Hoshizaki exclusive control board is employed in KM-2500SWH3 and KM-2500SRH3
Stackable Crescent Cubers.
• All models are pretested and factory-adjusted.
• For a control board check procedure, see "IV.B. Control Board Check."
CAUTION
1. The control board is 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.
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.
