What E4 means
E4 reads Humidity Sensor Failed on current Electrolux dryers with the two-character display, such as the ELFE7637AT, ELFE7437AW, ELFG7637AT and EFME627UTT. The dryer cannot tell how damp your laundry is. It finishes the cycle it is running, and manual timed cycles still work. The code is a flag that service is worth scheduling if it keeps appearing.
Common causes of E4
- Humidity sensor reading
- Sensor wiring
- Control board input for the sensor
1. Let the dryer finish the current cycle. 2. Use manual timed cycles for now. 3. Clean the lint screen and wipe the sensor bars inside the drum when cool. 4. Schedule service if the code keeps appearing.
- A failed sensor reading can come from the sensor, its wiring or the control, and we check each.
- We confirm that timed cycles still run normally.
- You get the price in writing before work starts.
Other Dryer codes
Can I keep using my dryer with E4?
Yes. It completes the cycle in progress, and manual timed cycles still work. Auto-sensing cycles are the ones affected.
Is E4 urgent?
No. It is a flag to schedule service if it continues, not an emergency.
What does the humidity sensor do?
It tells the dryer when clothes are dry so it can stop. Without it you need to pick a time yourself.
Still unsure about E4?
A technician diagnoses it on site and gives you the price in writing before any work starts.
