B. Service Diagnosis

WARNING

•The appliance should be diagnosed and repaired only by qualified service personnel to reduce the risk of death, electric shock, serious injury, or fire.

•Risk of electric shock. Use extreme caution and exercise safe electrical practices.

•Risk of electric shock. Control switch in "OFF" position does not de‑energize all loads (optional drain pump).

•Moving parts (e.g., fan blade) can crush and cut. Keep hands clear.

•CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place after the appliance is serviced. Make sure that none have fallen into the ice storage bin.

•Make sure all food zones in the appliance are clean after service.

The diagnostic procedure is a sequence check that allows you to diagnose the electrical system and components. Before proceeding, check for correct installation, proper voltage per nameplate, and adequate water supply.

Note: • When checking high-voltage (115VAC), always choose a white (W) neutral wire to establish a good neutral connection.

•When checking low-voltage (24VAC) (auxiliary code C-1 and later), always choose a light blue (LBU) neutral wire to establish a good neutral connection.

•When checking component voltage from CB, pull CB connectors out slightly to allow room for multimeter test leads contact.

•BCH energizes at startup and continues until the control switch is turned off or power is disconnected.

•Optional drain pump (HS-0248 or HS-5061) has 115VAC power supply as soon as the appliance is plugged into the electrical outlet.

1)Access the control box and move the control switch to the "OFF" position.

2)Clear any ice from BC.
