Fisher & Paykel Dryers F4 Error: Heating element fault

Fisher & Paykel dryer error code F4 is a mid-severity fault meaning Heating element open-circuit fault. The dryer is mechanically safe to run — the motor and drum are unaffected — but it will not dry clothes. Power-cycling may temporarily clear the display code if the fault was a loose connection, but F4 caused by a failed element or blown fuse will return immediately.

Answer to continue safely

Is it safe to keep using?

Maybe. The dryer is mechanically safe to run — the motor and drum are unaffected — but it will not dry clothes. If you need to use the dryer in an emergency, a timed cycle will tumble clothes in unheated air, which provides limited drying of lightly damp items only.

Can I reset the code?

Yes. Power-cycling may temporarily clear the display code if the fault was a loose connection, but F4 caused by a failed element or blown fuse will return immediately. Physical replacement of the faulty component is required for a lasting repair.

When to stop immediately?

Stop if you notice: Circuit breaker trips when the dryer starts, Burning smell accompanies the fault.

Symptoms You May Notice

F4 on display — no heat

The dryer tumbles normally but produces no heat. F4 is shown on the control panel at the start of or during the cycle.

Clothes still wet after full cycle

Without heating, even a full timed-dry cycle leaves laundry completely damp.

Cycle completes without error on timed settings

Some models default to completing the timed cycle in unheated tumble mode before displaying F4 at the end.

Possible Causes

1

Burned-out heating element

The resistance wire in the element assembly has burned through, breaking the heating circuit. This is the most common cause of F4.

DIY Possible
2

Blown thermal cutoff or thermal fuse

A one-shot thermal protection fuse in the element circuit has opened due to a previous overheat event, disabling the element.

DIY Possible
3

Loose element terminal connection

A push-on terminal on the element has worked loose due to thermal cycling, breaking continuity in the heating circuit.

DIY Possible
4

Failed heating relay on control board

The relay that switches mains voltage to the element has welded open or failed, preventing current from reaching the element.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Confirm no heat is produced

    Start a 10-minute timed-dry cycle and place your hand near (not touching) the exhaust vent outlet after 3–4 minutes. Cold exhaust air with a tumbling drum confirms a complete heating circuit failure.

    Warm but not hot exhaust may indicate a partial element failure rather than a complete open circuit.

  2. 2

    Check and reset the circuit breaker

    Electric dryers require two 240V legs. If one breaker leg has tripped, the dryer motor runs but the element does not heat. Reset both legs of the dryer circuit breaker.

    A repeatedly tripping breaker indicates a wiring or element fault — do not reset more than once without professional diagnosis.

  3. 3

    Test the heating element for continuity

    After unplugging, access the element assembly (typically via the rear panel on DE series). Disconnect the element wires and test resistance across the element terminals with a multimeter. A good element reads 8–25 Ω. Open circuit (OL) confirms element failure.

    Also test each element terminal to the dryer chassis — any continuity to ground indicates a shorted element that must be replaced immediately.

    Tools required
  4. 4

    Test thermal cutoff fuses

    Locate and test all thermal cutoff fuses in the element circuit for continuity. Replace any that read open circuit, but also clean the lint filter and exhaust duct before restoring power — a blown thermal cutoff indicates a prior overheat event.

    There may be two thermal protection devices in series on Fisher & Paykel electric dryers — test both.

    Tools required

When to Call a Professional

Contact a qualified technician if:

  • Element tests shorted to chassis ground — requires safe high-voltage component handling
  • Heating relay on the control board has failed
  • Wiring harness to the element shows heat damage or melting
