The answer up front
Dryer code F4E4 is the control reporting that the heat the cycle asked for did not arrive, and the circuit this code names is where the control looked. You can run an air-only cycle, but the heating circuit stays out until the fault is found. Nothing here needs a part until a thermal cut-out that opened because the air path was restricted, not because the heater failed has been ruled out.

The behaviour that comes with this code
- The cycle runs its full time and the load is still wet — Tumbling without heat looks normal from across the room.
- The drum stays cool to the hand after a cycle — The most direct test there is, and it needs nothing but a hand.
- NEAR MISS - the load is scorched rather than wet — Too much heat is the opposite fault and it belongs on the page for that symptom.
What produces this code, likeliest first
- A restricted air path that opened a thermal cut-out — Ranked first because the heater is usually innocent: a blocked duct overheats the housing, the cut-out opens to protect it, and the control then finds no heat at all.
- The circuit this code names open — Second: elements and their coils do fail open with age, and once open the circuit simply never heats.
The cheapest checks first
- Clear the lint screen and the vent before anything else — A restriction is the cause behind most opened cut-outs, and leaving it means the new part opens too.
- Check the outside hood for flow while the machine runs — Proof the path is open, which is what the heater depends on.
What an owner can safely do
- Run an air-only cycle to confirm the drum and blower are fine — Separates a heat fault from a drive or airflow fault without opening anything.
About 20 min
- Unplug the dryer or switch off its breaker before any panel comes off — A capacitor can hold a charge after the power is off.
Where the risk actually is
Safety
Unplug the appliance or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off. On a heating appliance, also give it time to cool: element terminals are both hot and live, and they are behind the panel for a reason. Leave the thermal cut-outs alone - working around one turns a cheap fault into a fire risk.
When a reset is not the answer
Call once you have proved the air path is clear and the drum still runs cold: an element, a thermal fuse and a relay are told apart with a meter behind the cabinet, and a gas machine adds an igniter and a valve coil to that list. Call before running it again if you smell scorching or see browned lint. A heating circuit behind a restricted duct is the fault that does not stay merely expensive.

The scope of this reading
This is generalized information about one code across the model lines that use this heating arrangement. 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.
