💡 Don’t panic! Replace ice maker assembly; improve ice room temperature control

📋 What You’ll Need

  • Ice maker assembly
  • Temperature sensor

🔧 Step-by-Step Repair Instructions

🔧 Step 1: Inspect ice maker for excessive ice

  1. Open the left French door of your Samsung RF23J9011SR refrigerator to access the freezer compartment on the bottom.
  2. Pull out the top freezer drawer completely by lifting it up slightly at a 15-degree angle when it reaches the stop point, then pulling forward.
  3. Look at the ice maker assembly mounted on the upper left wall of the freezer compartment, approximately 2 inches from the top and 3 inches from the left side.
  4. Examine the ice bucket directly below the ice maker for ice level—normal fill should be 4-6 inches deep, creating a mound that sits approximately 2 inches below the bucket rim.
  5. Check if ice has accumulated above the normal fill line and is touching or pressing against the ice maker’s ejector arm (the plastic arm that rotates to dispense ice).
  6. Inspect the area around the ice maker auger (the spiral metal shaft visible at the bottom of the bucket) for ice bridging—solid ice formations that connect multiple ice cubes into a single frozen mass.
  7. Look for frost buildup on the ice maker housing walls, which appears as white crystalline deposits thicker than 1/8 inch.
  8. Check the dispenser chute opening on the left refrigerator door for ice blockages by pressing the dispenser paddle and observing if ice flows freely or if you hear the auger motor running without ice dispensing.
  9. Examine individual ice cubes in the bucket—normal cubes measure approximately 1 inch x 1 inch x 3/4 inch and separate easily when touched.
  10. Identify clumped ice by attempting to scoop ice with your hand—if cubes don’t separate and move as a solid mass weighing more than 2 pounds, excessive ice buildup or freezing has occurred.

🛠️ Step 2: Check ice room temperature

  1. Open the left French door of your refrigerator to access the ice maker compartment located in the upper left corner of the fresh food section.
  2. Locate the ice room door—a clear or frosted plastic panel approximately 12 inches wide by 8 inches tall—and press the release tab at the bottom center to swing it open downward.
  3. Remove any ice cubes currently in the ice bucket by lifting the bucket straight up and out of the compartment.
  4. Insert a digital thermometer probe (accurate to 0.1°F) into the ice storage bin area, positioning it in the center of the empty bin, approximately 4 inches back from the front edge and 3 inches from the bottom.
  5. Close the ice room door and the refrigerator door completely.
  6. Wait 15 minutes to allow the temperature reading to stabilize without warm air interference.
  7. Open both doors again and quickly read the thermometer display before warm air affects the reading.
  8. Record the temperature—the ice room should read between 0°F and 5°F for proper ice production and storage.
  9. If the temperature reads above 10°F, locate the temperature sensor wire bundle, which is a thin white wire running along the right interior wall of the ice room at the 2 o’clock position near the ice maker assembly.
  10. Check that this sensor wire bundle is fully inserted into its connector clip—a white plastic rectangular housing measuring approximately 0.5 inches wide—and not hanging loose or disconnected.
  11. If the temperature reads below -5°F, note this for later adjustment of the refrigerator’s main temperature control settings.
  12. Replace the ice bucket by aligning the two rear tabs with the slots in the ice room and pushing down until it seats flush with the bottom surface.

⚙️ Step 3: Test defrost system

  1. Locate the defrost timer or control board—on the RF23J9011SR, this refrigerator uses an electronic control board mounted behind the top panel inside the refrigerator compartment, approximately 2 inches from the right side.
  2. Open the refrigerator door and remove the top shelf to access the overhead light and control panel area.
  3. Use a flathead screwdriver to release the 4 plastic clips securing the control panel cover—insert the blade 1/4 inch deep at each corner and twist gently to pop each clip.
  4. Pull the control panel cover forward 2 inches and set it aside to expose the main control board.
  5. Locate the defrost sensor (thermistor) wire connector on the control board—it’s a white 2-pin connector positioned at the bottom left corner of the board.
  6. Set your digital multimeter to the ohms (Ί) setting at 20K range.
  7. Disconnect the white 2-pin defrost sensor connector by squeezing the tab and pulling straight out.
  8. Touch the multimeter probes to the two metal pins inside the connector coming from the evaporator (not the board side).
  9. Read the resistance value—at room temperature (70°F), you should see between 10,000 and 12,000 ohms; this confirms the defrost sensor is functional.
  10. Locate the defrost heater connector—a brown 2-pin connector at the bottom right of the control board.
  11. Disconnect this brown connector using the same squeeze-and-pull method.
  12. Test resistance across the defrost heater terminals—you should read between 350 and 450 ohms, indicating the heating element has continuity.
  13. Reconnect both connectors—push each firmly until you hear a distinct click sound confirming proper seating.
  14. If either component reads “OL” (open/infinite resistance), that component has failed and requires replacement (sensor part #DA32-10105H, heater part #DA47-00244C).

🔩 Step 4: Replace ice maker assembly

  1. Locate the ice maker assembly mounted to the upper left wall of the freezer compartment, approximately 14 inches from the top and 3 inches from the left side wall.
  2. Identify the wire harness connector—a white plastic rectangular plug with 4 wires (red, white, black, and green)—located on the left side of the ice maker housing.
  3. Press down on the tab at the top of the wire harness connector while pulling it straight away from the ice maker. You’ll feel resistance for about 1/4 inch before it releases completely.
  4. Locate the fill tube—a white plastic tube approximately 3/4 inch in diameter—entering the ice maker from the back left corner.
  5. Twist the fill tube counterclockwise 1/4 turn, then pull it straight out from the ice maker inlet port.
  6. Find the metal mounting bracket securing the ice maker, positioned along the top edge of the unit.
  7. Using a Phillips #2 screwdriver, remove the two screws from the mounting bracket—one located at the front left corner and one at the back left corner, each approximately 2 inches from the respective edges.
  8. Lift the entire ice maker assembly upward by 1/2 inch to disengage it from the lower support tabs, then pull it forward and away from the freezer wall.
  9. Position the new ice maker assembly (part number DA97-08217A) by aligning the two lower tabs with the slots in the freezer wall, located approximately 12 inches from the top.
  10. Push the unit back until it sits flush against the wall, then lower it onto the support tabs until it drops into place with an audible click.
  11. Reinstall the two mounting bracket screws, tightening them until snug—approximately 8-10 inch-pounds.
  12. Push the fill tube into the inlet port on the ice maker’s left rear, then rotate it clockwise 1/4 turn until it locks.
  13. Connect the wire harness by pushing the connector straight in until you hear and feel a distinct click.

📋 Step 5: Verify proper temperature control

  1. Press the “Fridge” button on the control panel located on the upper-right interior wall, 3 inches below the ice dispenser chute, until the display shows 38°F (the factory default setting).
  2. Press the “Freezer” button directly below the Fridge button until the display shows 0°F (the factory default setting).
  3. Locate the ice maker control switch on the left wall of the freezer compartment, 8 inches down from the top shelf bracket—slide it to the ON position (toward the back wall).
  4. Open the refrigerator door and find the small round thermometer probe hole in the back wall, centered horizontally, 24 inches up from the bottom—this is the fresh food thermometer sensor location.
  5. Insert a digital probe thermometer through this hole approximately 1 inch deep into the air channel behind the wall.
  6. Close the refrigerator door and wait 2 hours without opening either door.
  7. After 2 hours, open the door and read the probe thermometer—it should display between 36°F and 40°F.
  8. Open the freezer door and place a second digital probe thermometer on the center of the middle wire shelf, not touching any frozen items.
  9. Close the freezer door and wait 2 hours without opening either door.
  10. After 2 hours, open the freezer door and read the thermometer—it should display between -2°F and +2°F.
  11. If the refrigerator reads above 40°F, press the Fridge button to decrease the temperature by 2-degree increments—wait 8 hours between adjustments.
  12. If the freezer reads above 2°F, press the Freezer button to decrease the temperature by 2-degree increments—wait 8 hours between adjustments.
  13. The cooling system functions correctly when both compartments stabilize within their target ranges and maintain those temperatures for 24 continuous hours.
