Problem: Fan speed sensor circuit fault – tachometer signal missing from multiple fans

How to Fix Refrigerator Error
1. Unplug refrigerator and systematically test tachometer circuits on all ECM fans.
2. Disconnect each fan harness and locate tachometer signal wire (typically yellow or green wire).
3. Measure resistance between tachometer wire and ground at fan motor (should be 1kΩ-10kΩ).
4. Check for continuity between tachometer wire at fan and control board connector.
5. Inspect wiring harness for damage near vibration points where tachometer wires commonly break.
6. If multiple fans show open tachometer circuits but motors test good, suspect harness damage at common routing point.
7. Trace harness from fans to control board looking for pinch points or rodent damage.
8. Repair damaged wires with waterproof heat-shrink connectors or replace entire harness section.
9. If harness tests good but tachometer signals still missing, replace main control board W11035831 (failed input circuits).
10. After repair, verify all fans report proper RPM in diagnostic mode.

Problem: Freezer fan overcurrent fault – excessive current draw detected

How to Fix Refrigerator Error
1. Unplug refrigerator immediately – overcurrent can damage control board fan drivers.
2. Remove rear wall panel in freezer compartment to access evaporator fan.
3. Manually spin fan blade – check for binding indicating seized bearings or ice obstruction.
4. Inspect fan blade for cracks or deformation causing imbalance and excessive current draw.
5. Disconnect fan wiring harness and measure resistance across motor terminals (should read 50-150 ohms).
6. Resistance below 30 ohms indicates shorted windings requiring motor replacement.
7. Check for short circuits between motor terminals and ground (should be infinite resistance).
8. Inspect wiring harness for damaged insulation causing intermittent shorts.
9. If motor resistance is low or shows shorts to ground, replace evaporator fan motor WPW
10. After replacement, monitor fan current draw during operation (should not exceed
11. 5 amps for 12V fans or
12. 3 amps for 120V fans).

Problem: Fan driver circuit failure on main control board

How to Fix Refrigerator Error
1. Unplug refrigerator and systematically test all fan motors and wiring harnesses.
2. Verify each fan motor resistance is within specification and wiring shows no damage.
3. Confirm proper voltage reaches each fan connector during operation.
4. If all fans and harnesses test good but none operate, suspect failed driver circuits on main control board.
5. Remove rear access panel to access main control board.
6. Inspect board for burnt components near fan driver transistors (small black transistors near edge connectors).
7. Check for cracked solder joints around driver components – reflow with soldering iron if found.
8. Measure resistance between fan power terminals and ground on board (should be infinite – low resistance indicates shorted driver).
9. If driver components show visible damage or resistance measurements indicate shorts, replace main control board W
10. After replacement, verify all fans operate correctly through multiple cooling cycles.

Problem: Freezer fan undercurrent fault – insufficient current draw indicating open winding

How to Fix Refrigerator Error
1. Unplug refrigerator and remove rear wall panel in freezer compartment.
2. Locate evaporator fan motor and disconnect wiring harness.
3. Measure resistance across motor terminals (should read 50-150 ohms).
4. If resistance is infinite (open circuit), motor windings have failed.
5. Inspect motor connector for bent pins or corrosion preventing proper connection.
6. Check wiring harness for broken wires near motor strain relief.
7. Verify proper voltage reaches fan connector during operation (12V DC or 120V AC).
8. If voltage is present but motor doesn’t run and resistance is infinite, replace evaporator fan motor WPW
9. After replacement, verify fan operates at correct speed and provides adequate airflow over evaporator coils.
10. Monitor temperature stabilization in freezer compartment within 2 hours of repair.

Problem: Communication error with the pantry drawer. The main fridge control cannot talk to the user panel on the drawer. Check the wiring harness at the hinge.

How to Fix Er 18F Error
1. - UNPLUG refrigerator from electrical power.
  - Locate freezer thermistor: typically behind evaporator cover or mounted on freezer wall.
  - Remove access panel covering evaporator coil (may require removing shelves/baskets).
  - Disconnect thermistor wiring harness. Note routing path before removal.
  - Measure resistance across thermistor terminals with multimeter at current freezer temperature. Compare to resistance chart in service manual (e.g., at 0°F/-18°C should be ~17kΩ).
  - If reading is infinite, zero, or significantly deviates from chart, replace thermistor.
  - Remove mounting clip/screw securing sensor. Gently pull sensor from clip/well.
  - Install new thermistor using OEM part W
  - Secure in mounting clip. Route wiring away from sharp edges.
  - Reconnect harness. Reassemble evaporator cover and interior components.
  - Restore power. Monitor freezer temperature display for 2 hours to confirm accurate readings.
