Error code E4A on the Frigidaire FFRE4120SW2 6.7 cu ft Front Load Electric Dryer means: Inlet Thermistor Open or Shorted. The inlet temperature thermistor (NTC sensor) that monitors air temperature entering the drum has an open or shorted circuit. Disconnect power and locate the inlet thermistor in the air duct near the heating element. Measure resistance — at room temperature (75°F) it should read approximately 10K-12K ohms. An infinite reading indicates open circuit; near-zero indicates a short. Replace the thermistor if out of range.
