Control Board - Hoshizaki Serenity Series KMS-830MLH Service Manual

C. Control Board
• A Hoshizaki exclusive solid-state control board is employed in Hoshizaki Crescent
Cubers.
• All models are pretested and factory set.
• For a control board check procedure, see "IV.B. Control Board Check."
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 style connector is used for all three.
K3 = Thermistor
K4 = Bin Control
K5 = Float Switch
5. Always replace the whole control board assembly if it goes bad.
6. Do not short out power supply to test for voltage.
