Shut off the water supply to the ice maker water valve.2. Remove the ice maker cover.3. Place the shut-off arm in the ON position (down).4. Make sure 120 VAC is available to the ice maker.5. Measure voltage across test points L and N. See Figure51. Voltage reading should be between 108 to 120 Vac. Ifno voltage present, check the continuity of the ice makerwire harness.Figure 52. Test points T and H.6. Short terminals T and H. An insulated jumper wire 14AWG with 1/2 inch stripped ends is recommended. SeeFigure 52. The following events should take place duringthe cycle:a. The mold heater begins to heat the mold.b. The ice maker ejector starts to cycle.c. About 15 seconds into the cycle, the thermostatproduces a “click” sound.Figure 51. Test points L and N.108 to 120 VacFigure 53. Water Fill Adjustment Screw andIndicator.Shorting test points T and H will start the cycle. Removethe jumper wire from test points T and H when a clicksound is heard or immediately after 15 seconds ofshorting terminals T and H.NOTERemove the jumper wire immediately after hearing the"click" sound or 15 seconds after shorting terminals Tand H. Failing remove to the jumper wire will causedamage to the heater and/or overheat the mold, whichwill ruin the ice maker.NOTEd. As the ejector fingers reach the 12 o'clock positionthe water valve energizes.6. If the water valve does not remain energized between 3.5and 7.5 seconds, see Water Fill Adjustment, page 70.WARNING:Burn hazard! The mold heater will heat the bottomof the mold. Handle or grasp the ice maker by itssides when performing a cycle test.DONOTROTATEMANUALLYVL T HMNDISCONNECT POWERTO REMOVE MODULE UR 185W-115V-60 HZIM # S 106 62664911 MAY 00 WB1Shut-Off Arm(ON position)MIN MAX RANGE HOLD HHzRELmAAmVVVOFF!!A COM VmA μA1000V MAX400mA MAXFUSED10A MAXFUSEDPEAK MIN MAXμACAT II4 1/2 DIGITS1 Seconds87TRUE RMS MULTIMETERIIIVVDONOTROTATEMANUALLYVL T HMNDISCONNECT POWERTO REMOVE MODULE UR 185W-115V-60 HZIM # S 106 62664911 MAY 00 WB1Insulated Jumper Wire(14 AWG with 1/2" stripped ends)Shut-Off Arm(ON position)DONOTROTATEMANUALLYVL T HMNDISCONNECT POWERTO REMOVE MODULE UR 185W-115V-60 HZIM # S 106 62664911 MAY 00 WB1Water fill adjustmentalignment indicatorWater filladjustmentscrew
