Electrolux Dryer E4 Error Code — Meaning & Repair Cost (2026)
Humidity (moisture) sensor error — the control detects an abnormal moisture-sensor signal, disrupting auto-dry cycles. Below: the most likely causes, and what the matching repair costs — Estimated national ranges with a metro localizer. Reviewed July 2026.
What E4 means
Humidity (moisture) sensor error — the control detects an abnormal moisture-sensor signal, disrupting auto-dry cycles.
Likely causes, most common first
- A defective humidity/moisture sensor, corroded or fouled sensor bars, a wiring/connection failure, or a main-board fault.
Also applies to Frigidaire — these brands share the same control platform, so the code and its causes read the same.
