IV. Service Diagnosis

WARNING

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

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

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

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

5.Make sure all food zones in the icemaker and storage bin are clean after the unit is serviced. For cleaning procedures, see "VI. Cleaning and Maintenance."

A. Ice Production Check

To check production, prepare a bucket or pan to catch the ice and a set of scales to weigh the ice. After the icemaker has operated for 10 to 20 minutes, catch the ice production for 10 minutes. Weigh the ice to establish the batch weight. Multiply the batch weight by 144 for the total production in 24 hours. When confirming production or diagnosing low production, see "III. C. Performance Data" for typical production information.

B. Diagnostic Procedure

This diagnostic procedure is a sequence check that allows you to diagnose the electrical system and components. Before proceeding, check for correct installation, adequate water supply (minimum of 7 PSIG, maximum of 113 PSIG), and proper voltage per unit nameplate. When checking voltage (115VAC), always choose a white (W) neutral wire to establish a good neutral connection.

1)Move the power switch to the "OFF" position, then unplug the unit from the electrical outlet.

2)Remove the front panel and louver. Remove the screws securing the control box, then gently pull the box out. Remove the control box cover.

3)Plug the unit back in. Place the power switch in the "ON" position.

4)Freeze Cycle – GM, FM, CR, and Comp energize. Ice production begins 4 to 6 minutes after Comp starts depending on ambient and water conditions.

Diagnosis: Check that GM, FM, and Comp start. If not, check the power switch, STS (see "III.B.3.c) Low Water/Freeze-Up Safety Shutdown"), BC assembly (including heater), GM protector (external overload) (see "III.B.3.d) Gear Motor Protector (external overload) Shutdown"), GM thermal protector (internal overload), GM windings, GM capacitor, voltage to FM, voltage on CR, PTC relay, voltage on Comp terminals, Comp windings, and Comp thermal protector (external overload). If optional drain pump HS0248 is installed, see "IV.D. Optional Drain Pump HS-0248." If GM starts, but the auger does not turn, check the spline coupling between the auger and GM.
