The short version
F4E2 is a report, not a diagnosis: it says the circuit this code names did not respond the way a working heating circuit does. A no-heat dryer is not dangerous, it is useless, and running it for hours is how the fault costs money. Work down the ranked causes rather than ordering the part the code names.

| F4E2 Error Code | Potential Cause: Main Heater |
What you actually see and hear
- The cycle runs its full time and the load is still wet — Tumbling without heat looks normal from across the room.
- The cycle ends early with the code on the display — The control gives up once the temperature does not follow the demand.
- 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.
- A thermostat or thermal fuse that has opened for good — Third: the protective parts are consumable, and a fuse that has done its job stays open until it is replaced.
Check these in this order, and why
- Feel the drum at the end of a cycle — Free, immediate, and it tells you whether you are chasing heat or airflow.
- Check the outside hood for flow while the machine runs — Proof the path is open, which is what the heater depends on.
The safe checks, step by step
- 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.
What to do before any panel comes off
Safety
Before anything: unplug the appliance or switch off its breaker, because a capacitor can hold a charge after the power is off. Then wait for it to cool. A restriction that has opened a thermal device must be cleared as part of the repair - fitting a new device into a blocked air path is how the same fault comes back hotter.
The point at which you call
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.

What is deliberately not here
Written for the model lines that use this heating arrangement, this page describes what the code means and how to work through it, nothing more specific. Part numbers, connector layouts and resistance tables differ from one family to the next and are not guessed at here. A family-level or model-level page, where one exists, is the better answer for your unit - the index below lists what is available.
