III.Controls and Adjustments

•A Hoshizaki exclusive control board is employed in KM series appliances.

•All models are pretested and factory adjusted.

•For a control board check procedure, see "II.C. Control Board Check."

NOTICE

•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 icemaker when handling or replacing the control board.

•Do not touch the electronic devices on the control board or the back of the control board.

•Do not change wiring and connections. Do not misconnect K3 WHITE, K4 RED, and K5 BLACK, because the same connector is used for the thermistor, mechanical bin control, and float switch. K4 RED is not used on "E" control board models.

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

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