ON/OFF Shut-off Arm Switch Mid-South Mid-South Mid South - This compact design is a variation of previous designs. Operation is identical except for the following: The metal feeler arm has been replaced with a plastic paddle that moves up and down on a cam.
Operation Mid-South Mid-South Operation Icemaker Operational Cycle Both the Compact and the Modular icemakers rely on a combination of electrical and mechanical functions to create and eject ice. The complete ice cycle for the Compact icemaker is described below and is divided into six major functions. The Modular ice- maker cycle is also divided into the same six functions but requires only one revolu- tion to complete the ejection of the ice.
Water fill- At the end of the second revolution, an internal cam in the icemaker ener- gizes a fill switch. The switch turns on the icemaker water valve and water is allowed to enter the icemaker. Terminate- Once filled with water, the icemaker cycle terminates. The icemaker is now ready to repeat the cycle.
After Three Seconds (Second Revolution) Just as before, the cam continues its rotation and the hold switch contacts transfer to the normally open position. The feeler arm begins to raise. The shut-off switch con- tacts transfer and the ejector blades resume their sweep. If the bucket is full, the feeler arm will come to rest on top of the ice and prevent the shut–off switch from resetting.
New Generation Schematic 120 Volt 60 Cycles (New) On/Off Switch (New) Mid-South Mid South design incorporates an ON/OFF switch and Thermal Cut out. These fea- tures were not on the original Whirlpool compact design.
Removing Cover Mid-South Remove one screw to remove front cover. Cover Removed Water fill adjustment screw Drive gear On/Off switch Mid-South Mid-South With the cover removed the drive gear and water fill adjustment screw are accessible.
Water Fill Adjustment Water Fill Adjustment Screw Clockwise decreases volume Counterclockwise increases volume ½ turn = approximately 13cc Note: Check all possibilities that could cause a short or long fill before making a fill adjustment Mid-South Water Fill Adjustment Many of compact icemakers used today are equipped with a water fill adjustment. Turning the fill adjustment screw changes the alignment between the cam and switch and alters the amount of time the fill switch is energized.
Before manually initiating a cycle, check the position of the ejector arm. Assuming the problem is in the icemaker, the position of the ejector arm will give you an indica- tion of the failed component. If the ejector blades are still in the home position (9 o’clock) the thermostat is most likely at fault.
Releasing Wire Harness Cover Insert a small blade screwdriver and depress release as you slide off the cover Mid-South To remove the ice maker, begin by removing the wire harness cover. This is accom- plished by using a small blade screwdriver to depress the “hidden” catch that secures the cover to the cabinet.
Removing Icemaker Mid-South Removing the cover exposes the icemaker wiring harness. Disconnect Electrical Wiring Harness must be disconnected to remove icemaker assembly Mid-South Disconnect the icemaker wiring harness.
Slide Out Assembly Ice Maker assembly removed Mid-South With the harness disconnected, the icemaker can be removed, there is enough har- ness available to connect the icemaker when removed from the cabinet to initiate a water fill or harvest if necessary.

Modular Ice Maker Operation Operation Modular Switching Switching in the modular icemaker is accomplished by wiper contacts which ride on copper strips located behind the drive gear. As the gear rotates, the wiper contacts open and close the circuit to the individual components. The Modular Icemaker Cycle As with the Compact Icemaker, harvesting of the ice is initiated with the closing of the thermostat.
Resistance Checking A resistance check can be performed on all components from the front of the module Test points (cover removed) Modular Resistance Checking of Components The icemaker components can also be resistance checked through the front of the module. Inserting the ohmmeter leads between test points L and H will check the resistance of the heater (72 ohms, ±...

Initiating a Harvest Cycle Jump Across T and H Remove jumper after about 3 seconds, before the blades reach the 10 o’clock position Modular Initiating a Test Cycle Removing the front cover of the icemaker will expose the test points on the module. These test points can be used to test components and to initiate an ice harvest cycle.
Troubleshooting • No Ice Production • Low Ice Production Most Common Problems: • Bail Arm in off position • No water or Insufficient water charge • Freezer Temperature too warm Diagnosis of any icemaker begins with a visual inspection of the entire ice making system.
Troubleshoot system. Once the visual inspection is completed, verify your diagno- sis before replacing the icemaker. Whirlpool Ice Production Whirlpool manufactured refrigerators: • 8 or 5 cubes per harvest depending on style of ice maker • Average time of ice production…...
Modular (Whirlpool) ~ 1 harvest per 50 minutes (26+ per day). ~ 208 cubes Reason: The faster ice rate with the Whirlpool icemaker is due to the new centrifugal blower system that will be incorporated at the same time the Whirlpool IM is imple-...
Low Ice Production • Step 1: Check Freezer temperature (optimal 0°F, ±3°F) – Adjust Freezer temperature as needed • Lower Temp for More Ice Note: The average temperature of the Iceland ice maker compartment is 15 degrees F. (The set point of the ice maker compartment is 25 degrees if the icemaker switch is turned "off").
If the cubes vary in size, insure that the refrigerator is leveled properly. Uneven cubes may be caused by either the front of the icemaker being higher or lower than the back and most of the water collecting at the low end of the icemaker. Leveling the refrig- erator will cure the problem.
Saddle Valves Do Not Use Self-Tapping Recommended Saddle Valve Drill Type Saddle Valve Self Tapping Water Valve Excessive mineral deposit build up at the saddle valve shut-off- Most icemaker water installations are done with a clamp-on saddle valve. Two types of saddle valves are available to installers and consumers: The drill type saddle valve requires that the installer or consumer drill a hole in the water pipe before the valve is installed.
Checking Water Charge • Remove Icemaker from mounting but leave connected to harness • Start a Harvest Cycle • Catch fill water in baby bottle Correct Water Charge ranges from 113 cc/ml. to151 cc/ml. (Approx 4 to 5 Ounces) • Adjust Fill Volume as Needed Note: Check all possibilities that could cause a short or long fill before making a fill adjustment...

No Ice Production • Step 1: Visually inspect icemaker. Is the icemaker arm fully lowered to “ON’ position? If yes, go directly to step 2. If no, check for free movement of the feeler arm. Remove any ice cubes that may be keeping the feeler from lowering to the “ON”...
