The short version
What F4E5 tells you is that the blower that pulls air through the drum is not moving the air the control expects. You can start it again, but a restricted dryer wastes heat and is the shape of fault that ends in a scorched load. Start with lint in the duct or a crushed vent hose behind the machine rather than with a part.
This code, as the manufacturer publishes it

| F4E5 Error Code | Potential Cause: Drying Fan |
The behaviour that comes with this code
- Clothes come out hot but still damp — Heat with no air movement is exactly this fault.
- The drum or the door glass is hotter than usual — Heat that should have left with the air stays in the cabinet.
- NEAR MISS - the drum does not turn at all — That is a belt or a drive fault, not an airflow fault, and it belongs on that page.
What produces this code, likeliest first
- A blocked or crushed vent duct — Ranked first and by a wide margin: lint accumulates in the duct, the hose gets crushed against the wall when the machine is pushed back, and either one produces this code with a perfectly healthy fan.
- The blower wheel slipping or damaged — Third: a wheel that has lost its grip on the shaft spins without moving air.
Where to start, and what follows
- Pull the lint screen and hold it to the light — Free, thirty seconds, and it is the cause more often than anything else here.
- Look at the vent hose behind the machine — A crushed hose is visible from where you are standing.
What an owner can safely do
- Straighten or replace the vent hose and pull the machine out a little — A hose crushed flat behind the machine restricts more than a long duct run does.
About 20 min
- Clear the duct and check for flow at the outside hood — Airflow you can feel at the hood is the proof the path is open.
Tools: vacuumAbout 30 min
- STOP HERE if the blower housing has to come apart — Unplug the dryer or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off.
Before you open anything
Safety
Safety line for this appliance: unplug it or switch off its breaker before removing any panel, and remember a capacitor can hold a charge after the power is off. Interlocks and switches stay as fitted. A hot plug, a browned outlet or the smell of hot insulation all mean stop and call, whatever the code says.
When this is a service call
The line is straightforward. Call when the code returns with a clean screen, a straight hose and flow at the hood: a blower wheel and a fan motor are both behind the cabinet and the drum usually comes out to reach them. Separately and more urgently: stop using it and call if you smell scorching or see lint browned by heat. Heat with no airflow is how a dryer fire starts, and lint is the fuel.

How far this page applies
This is generalized information about one code across the vented model lines that monitor airflow through the drum. It does not carry the numbers that belong to a specific unit: wiring colours, resistances and part numbers are family-specific, and they are the reason a service manual exists. If your family or model has its own page, read that one first - it is the more specific answer - and the code index below is where to look for it.
