b) Opti-Serve Model – "ICE" and "AM" LEDs are on:

(1) "CONTINUOUS" Mode: Before engaging the ice dispense Opti-Serve sensor, check for 5VDC from the locations given in the table below. If VDC is different than in the table, replace CB. If VDC is correct, engage the Opti-Serve sensor and confirm that VDC matches the table below. If not, see "IV.F.3a. Ice Dispense "CONTINUOUS" Mode" to rule out a faulty Opti-Serve sensor. If the Opti‑Serve sensor checks out, replace CB. If VDC matches the table below when the Opti‑Serve sensor is engaged and ice is not dispensed, check CB K2 connector pin #6 (LBU wire) for 115VAC. If 115VAC is not present, replace CB. If 115VAC is present, check DS and DM continuity. Replace as needed.
