Electrolux ELFE7637AT 7.4 cu ft Electric Dryer with Steam Refresh and Wrinkle Care E4A Error Fix: Inlet Thermistor Open or Shorted

Error code E4A on the Electrolux ELFE7637AT 7.4 cu ft Electric Dryer with Steam Refresh and Wrinkle Care means: Inlet Thermistor Open or Shorted. The inlet temperature thermistor (NTC sensor) that monitors the air temperature entering the drum has an open or shorted circuit. The dryer cannot accurately monitor incoming air temperature. Disconnect power and locate the inlet thermistor — it is typically mounted in the air duct near the heating element. Measure thermistor resistance — at room temperature (75°F) it should read approximately 10K-12K ohms. An infinite reading indicates an open circuit; a near-zero reading indicates a short. Check the wiring for damage. Replace the thermistor if out of range.
