Whirlpool Dryer F4E3 Error: Heating element open
If you are dealing with a whirlpool dryer f4e3 error, this guide will help you understand the cause and find the right solution quickly. What Does Error Code F4E3 Mean? Error code F4E3 on your Whirlpool electric dryer means the heating element has an open circuit — a break in the resistive wire coil that […]

Answer to continue safely
Is it safe to keep using?
Maybe. The dryer will run without overheating risk since the element is open, but it will not dry clothes. Running it is not harmful but also not useful.
Can I reset the code?
No. A burned-out element cannot be reset. It must be physically replaced along with the thermal fuse.
When to stop immediately?
Stop if you notice: Stop running cycles once the fault is confirmed — each useless cycle wastes electricity with no drying result., Stop and clean the exhaust duct before installing a new element, or the replacement element may fail prematurely for the same reason..
Symptoms You May Notice
Clothes are completely cold and wet after a full drying cycle
The drum tumbles normally for the entire cycle duration but no heat is produced, so laundry comes out as wet as it went in.
Exhaust vent blows cool room-temperature air
Holding a hand near the exterior exhaust vent during operation reveals no warmth, confirming the heater is not activating.
Drying time on automatic cycles is extremely long before shutdown
Moisture sensor cycles may run for the maximum time before timing out, as the sensor never detects the warmth-assisted evaporation it expects.
Cycle completes normally but interior of drum is cold
Opening the door immediately after a cycle ends reveals a drum at room temperature, which is a clear sign of zero heat production.
Possible Causes
Burned-out heating element
The resistive coil wire has broken, creating an open circuit that prevents current flow through the element.
DIY PossibleBlown thermal fuse
The thermal fuse on the heater box has blown due to overheating, cutting power to the element as a safety measure.
DIY PossibleBlocked exhaust duct causing repeated overheating
A clogged or kinked duct traps heat and repeatedly overloads the element until it fails.
DIY PossibleSafe Checks You Can Do
-
1
Confirm no heat with a short test cycle
Run a 10-minute timed dry on High heat. Check the exhaust vent outlet for warmth after 2–3 minutes. Room-temperature air confirms a heater fault.
Do this before opening the dryer to confirm the symptom before investing repair time.

2
Test the heating element resistance
Unplug the dryer and remove the back panel. Disconnect the two element lead wires and measure resistance across them. Good range: 8–11 ohms. Open (OL) = burned out element.
Inspect the element coil visually through the heater box housing for a visible break or dark burn spot.

Test and replace the thermal fuse
Locate the thermal fuse on the heater box exhaust outlet. Test for continuity — a good fuse reads near zero ohms. An open fuse must be replaced. Always replace both the element and the thermal fuse together.
Never bypass the thermal fuse — it is a critical fire-safety device.

When to Call a Professional
Contact a qualified technician if:
- A new element and thermal fuse are installed and confirmed good with a multimeter, but F4E3 persists — the control board relay may also be faulty.
- Multiple elements have failed in a short period, indicating a deeper airflow obstruction or voltage problem that needs professional diagnosis.
