Important Tips for Frigidaire Models

  • EC error code specifically indicates sealed system or electronic control fault on many Frigidaire models

Possible Causes

Electronic control or sealed system fault

How to Identify: Error code ‘EC’ displayed; unit stops dehumidifying; possibly accompanied by shutdown to protect system

Part: Control board / sealed refrigeration system (compressor, coils, refrigerant)

Sensor malfunction (temperature/humidity)

How to Identify: Codes like AS, F1, F2 often appear; inaccurate humidity readings or erratic behavior reported

Part: Humidity or temperature sensors

Airflow restriction (dirty filter or obstructed vents)

How to Identify: EC and other codes clear after cleaning; restricted airflow causing coil freezing mimicking error code

Part: Air filter / intake vents

Improper environmental conditions (temperature too low/high)

How to Identify: Error codes appear when ambient temperature outside recommended range; unit coils freeze or overheat

Part: Operating environment
