Testing the ice maker in a KitchenAid refrigerator

Water is available, the water dispenser works normally.

Although built together, water dispenser and Ice Maker valves work independent of each other. One side could fail while other is working normally. Also the ice maker itself must call for the water, so even if water is available that doesn't mean the ice maker is calling for it. Jump ports L and V to energize valve. Also using the test ports on the module will help you far more than disassembling the ice maker.

All resistance checks must be done with power disconnected from the icemaker or whole appliance!

  • Testing for voltage between test points L and N should measure 120 volts if the icemaker is receiving power. Note: On some models power is disconnected from the icemaker whenever the door is opened.
  • Testing for resistance between test points L and H will check the icemaker's mold heater (~72 ohms).
  • Testing for resistance between L and M will check the motor resistance (~4400 - 8800 ohms).
  • Testing for resistance between V and N will check the resistance of the external water valve solenoid coil (~300 ohms).
  • Testing for resistance between T and H should show continuity (zero resistance) if the icemaker's internal bimetal thermostat is closed. It will read infinite resistance if open. Testing for voltage should show 0 volts if the icemaker's internal thermostat is closed, 120 volts if the thermostat is open... and the icemaker is getting power. Note: The internal icemaker thermostat will only be closed if the icemaker is and has been below 15°F for some time.

A 14 gauge insulated (except for 1/2" on each end) preferably solid-wire can be used as a jumper to initiate functions of the icemaker unit.

Testing on a 'live' appliance can be dangerous! Anyone unfamiliar with proper safety precautions should not attempt it.

  • Jumping between T and H will simulate the closing of the internal thermostat. It will initiate a harvest cycle, powering the icemaker motor and the mold heater. Remove the jumper after 3 seconds and icemaker should continue to run. Note: If the jumper is not removed before the ice ejector blades reach the 10:00 o'clock position, the water valve will not be energized and the icemaker will not fill.
  • Jumping between M and N should power the icemaker motor.
  • Jumping between L and V should energize the water valve.
  • Jumping between H and N should energize the ice mold heater.

To initiate a TEST CYCLE:

Press the TEST button located at the bottom of the icemaker head---for half-a-second.

This will induce a "forced harvest".

How to adjust the water fill amount in a Samsung refrigerator ice maker

Posted by Samurai Appliance Repair Man , in Icemaker Repair 02 November 2011 · 4,535 views

Grand Master Funk kdog calls out the keyboard dance steps for this adjustment:

It's kind of complicated to make the adjustment, only 2 ice levels are available - 85cc fill and 95cc fill, Initially the unit comes set for the 85cc fill and would have needed to be increased to be on the high setting.

Press and hold "Freezer" button and "Power cool" (the middle button on left, and upper on right) - hold them simultaneously for 12 seconds, and the control will enter an adjustment mode. The displays on the left side will show a code, and the display on the right will show a reference or adjustment segment. You want the number on the right to display "2" (one of the r/h keys will cause the number to change), once it shows "2" - the work the l/h keys to make the left display number show "0". Once you have these numbers displayed, do not input anymore and 20 or 30 seconds later, the control will store the setting and go back to normal display mode.
