Electrolux EI23BC82SS (Counter-Depth French Door) – Temperature sensor failure Repair Guide

🔧 Step 1: Test thermistor readings

1. Unplug the refrigerator from the wall outlet and wait 5 minutes for capacitors to discharge.
2. Open the refrigerator door and remove all items from the top shelf to access the rear wall panel.
3. Locate the white plastic air tower panel on the rear wall of the fresh food compartment, approximately 18 inches from the bottom and centered left-to-right.
4. Remove the 4 Phillips-head screws (Phillips #2 screwdriver) securing the air tower cover—two screws at the top corners and two at the bottom corners.
5. Pull the air tower cover forward and lift it up to unhook it from the mounting tabs at the bottom.
6. Identify the thermistor sensor—a small black cylinder approximately 3/8 inch in diameter with two wires (typically white and blue) attached via a white connector, located on the right side of the evaporator coil housing.
7. Disconnect the thermistor by pressing the locking tab on the white connector with your thumb and pulling the two halves apart—they will separate with approximately 1/4 inch of movement.
8. Set your digital multimeter to the resistance (Ω) setting at 20K or 200K range.
9. Touch the multimeter’s red probe to one thermistor terminal and the black probe to the other terminal (polarity doesn’t matter for resistance testing).
10. Read the resistance value on the display—at room temperature (70°F), the thermistor should read between 8,000 and 10,000 ohms.
11. For freezer thermistor testing, repeat steps 2-10 but access the freezer compartment and locate the thermistor on the left side wall behind the white plastic panel (secured with 3 Phillips screws).
12. At 0°F (freezer temperature), the freezer thermistor should read approximately 16,600 ohms; at room temperature it should read 8,000-10,000 ohms.

🛠️ Step 2: Check sensor connections

1. Open the refrigerator door and locate the fresh food thermistor sensor wire connector on the upper right interior wall, approximately 3 inches below the ceiling and 2 inches from the right side.
2. Trace the white wire bundle from the thermistor down to the main control board housing located behind the temperature control panel in the upper fresh food section.
3. Remove the temperature control panel by pressing the two plastic tabs on each side (one at 3 o’clock position, one at 9 o’clock position) and pulling the panel forward 1 inch until it releases.
4. Identify the fresh food thermistor connector – a white 2-pin connector with red and black wires located on the left side of the control board, third position from the top.
5. Grasp the connector body (not the wires) and pull straight out with steady pressure until it disconnects from the board socket.
6. Inspect the metal pins inside both the connector and board socket for corrosion, oxidation (green/white buildup), or bent pins.
7. If oxidation is present, spray electrical contact cleaner (part number CRC 05103) directly into both the connector and socket, then wipe with a lint-free cloth.
8. Straighten any bent pins using needle-nose pliers by grasping the pin base and applying controlled pressure in the opposite direction of the bend.
9. Push the connector firmly back into the board socket until you hear a distinct click – this indicates full insertion with proper pin contact.
10. Repeat steps 4-9 for the freezer thermistor connector – a white 2-pin connector with blue and black wires located directly below the fresh food connector on the control board.
11. Test each connection by attempting to pull the connector straight out while applying 5-10 pounds of force – properly seated connectors will not release.
12. Reinstall the temperature control panel by aligning the bottom tabs first, then pressing upward until both side tabs click into place.

⚙️ Step 3: Verify temperature accuracy

1. Place a refrigerator thermometer (the glass tube type with colored liquid or digital probe style) in a cup filled with 8 ounces of tap water.
2. Set the cup with thermometer on the middle shelf of the fresh food compartment, centered left-to-right, approximately 8 inches back from the door edge.
3. Close the refrigerator door and wait 8 hours without opening the door to allow temperature stabilization.
4. Open the door, immediately read the thermometer without removing it from the water, and record the temperature.
5. Compare your reading to the target range of 37°F to 40°F (the ideal setting is 38°F).
6. If the temperature reads above 40°F, locate the electronic control panel on the ceiling of the fresh food compartment, 2 inches from the front edge.
7. Press the “Fridge” button once, which will display the current set point temperature.
8. Press the down arrow button to decrease the set point by 2°F.
9. Press the “Fridge” button again to confirm the new setting (you’ll hear a single beep).
10. If the temperature reads below 37°F, repeat steps 6-7, then press the up arrow button to increase the set point by 2°F, followed by pressing “Fridge” to confirm.
11. Wait another 8 hours and repeat steps 1-5 to verify the adjustment.
12. For the freezer, place a freezer thermometer directly on the middle wire shelf, centered in the compartment.
13. Wait 8 hours, then read the thermometer, which should display between -2°F and +2°F (ideal is 0°F).
14. Adjust using the “Freezer” button on the control panel following the same procedure as steps 6-10, changing the set point in 2°F increments.
15. If temperatures remain outside acceptable ranges after two adjustment cycles, the thermistor or control board requires replacement—proceed to diagnostic steps.

🔩 Step 4: Replace faulty thermistors

1. Locate the refrigerator compartment thermistor on the right side wall, approximately 18 inches from the top, hidden behind a white plastic air duct cover secured by two T20 Torx screws.
2. Remove both T20 Torx screws using a T20 Torx bit and set them aside.
3. Pull the air duct cover forward and down to release it from the mounting clips at the bottom edge.
4. Identify the thermistor—a small cylindrical sensor approximately 1 inch long with a white or gray wire harness attached, clipped into a metal bracket.
5. Press the locking tab on the wire connector with your thumb while pulling the connector straight back to disconnect it from the control board harness.
6. Squeeze the metal retaining clip on both sides and pull the thermistor bulb straight out from its mounting grommet.
7. Locate the freezer compartment thermistor on the rear wall, 12 inches from the top and 8 inches from the left edge, behind the evaporator cover (which should already be removed from previous steps).
8. Disconnect the freezer thermistor’s wire connector by pressing the release tab and pulling straight back.
9. Remove the freezer thermistor from its clip mount using the same squeeze-and-pull technique.
10. Insert the new refrigerator thermistor (part number 5303918202) into the mounting grommet, pushing firmly until you feel it seat completely—the rubber grommet will compress around the sensor bulb.
11. Connect the wire harness by aligning the connector and pushing until you hear a distinct click.
12. Insert the new freezer thermistor into its clip mount until the retaining clip snaps closed.
13. Connect the freezer thermistor wire harness, pushing until it clicks into place.
14. Reinstall the refrigerator air duct cover by engaging the bottom clips first, then rotating upward.
15. Install both T20 Torx screws and tighten until snug—approximately 8-10 inch-pounds of resistance.

📋 Step 5: Calibrate temperature

1. Press and hold the “Freezer Temperature” and “Refrigerator Temperature” buttons simultaneously for 5 seconds until you hear a single beep and the display shows “Sb” (Sabbath mode indicator flashes briefly, then clears).
2. Release both buttons, then immediately press the “Freezer Temperature” button 4 times within 3 seconds. The control panel will display “01” indicating you’ve entered calibration mode.
3. Look at the current temperature offset value displayed on the refrigerator side panel (ranges from -5 to +5 degrees Fahrenheit).
4. Press the “Refrigerator Temperature Up” arrow button to increase the offset by 1 degree, or press the “Down” arrow to decrease by 1 degree. Each button press changes the value by 1°F increments.
5. Wait 3 seconds after selecting your desired offset value. The display will flash twice confirming the new calibration setting.
6. Press the “Freezer Temperature” button 4 more times within 3 seconds to switch to freezer calibration mode. The display will show “02”.
7. Adjust the freezer offset using the same up/down arrow method, selecting between -5 and +5 degrees Fahrenheit based on your thermometer readings from earlier steps.
8. Wait 3 seconds for the double flash confirmation after setting the freezer offset.
9. Press and hold both temperature buttons simultaneously for 3 seconds to exit calibration mode. The display will return to showing actual compartment temperatures.
10. Place your refrigerator thermometer in the center of the middle shelf and freezer thermometer on the center wire rack.
11. Wait 8 hours without opening either door for temperatures to stabilize with the new calibration settings.
12. Check both thermometers after 8 hours. Refrigerator should read 37°F and freezer should read 0°F (±1 degree). Repeat calibration process if readings remain outside acceptable range.
