What the Error Code Means
Error code E4 generally means the dryer detected a communication or control condition outside the expected range.
It points to a control status rather than a confirmed single failure.
Common Symptoms You May Notice
- The display shows E4 and the dryer may beep.
- The cycle stops early with the alert displayed.
- Buttons may respond inconsistently.
Most Common Causes (From Least to Most Serious)
- Temporary control glitch: A brief interruption can cause a communication alert even when drying is normal.
- Power interruption: A short outage or voltage dip can trigger a control alert.
- Control status is outside the expected range: In some cases the dryer pauses when it cannot confirm normal control communication.
Safe Things You Can Check Yourself
- Power cycle the dryer: turn it off, wait one minute, and turn it back on.
- Confirm the power cord is fully seated in the outlet.
- Try a different cycle after the reset.
If at any point this feels unsafe or unclear, stop and contact a professional.
When to Stop and Call for Service
- The E4 code returns after a reset.
- The dryer will not start or keeps shutting down.
- You notice burning smells, sparking, or repeated shutdowns.
Typical Repair Cost Range
