Error Code: F4E3 Difficulty: Easy
Problem: Restricted airflow is detected. This is the same as the ‘AF’ code and can be caused by a clogged lint screen or vent issues.
How to Fix F4E3 Error (Step-by-Step)
- First, pull out the dryer’s lint screen and clean it completely, as even a thin layer of lint can restrict airflow.
- For safety, unplug the dryer from the electrical outlet before checking the vent.
- Look inside the slot where the lint screen goes and use a vacuum cleaner with a crevice tool to remove any lint that has built up.
- Carefully pull the dryer away from the wall to get to the exhaust vent hose.
- Check the hose for any kinks or sharp bends that could be blocking air, then disconnect it and clean it out thoroughly.
- Go outside and check the vent cover. Make sure the flap can move easily and is not clogged with lint or debris.
- After ensuring the entire path is clear, reconnect the hose, plug the dryer in, and it should work correctly.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
