What is the Whirlpool Dryer F4E3 error?#
F4E3 is a gas-heat fault: the gas-valve relay on the control board is not switching the burner reliably, so the dryer often heats at first, then goes cold. You may see the igniter glow repeatedly without the burner lighting. If you ever smell gas that does not ignite, shut off the gas supply valve, ventilate the room, and stop — do not keep troubleshooting.
F4E3 on a Whirlpool Dryer: likely causes and repair cost#
On a Whirlpool Dryer, the F4E3 code signals: gas valve relay.
| Likely cause | Typical likelihood |
|---|---|
| Gas-valve relay on the control board failed to switch | Most common |
| Weak valve solenoid coils no longer holding the valve open | Common |
| Igniter drawing out of spec so the relay never sees a valid light sequence | Less common |
Typical professional repair: $130–$350 · Difficulty: professional only · usually a technician job
Symptoms that often accompany F4E3: Gas dryer heats initially then goes cold; Igniter glows repeatedly but burner does not light; Gas smell when dryer first starts (unburned gas); Dryer takes 2-3 cycles to fully dry clothes
Technician diagnostic sequence for F4E3:
- Verify the gas supply valve behind the dryer is fully open
- Check the gas valve solenoid coils on the burner assembly — there are typically two coils in series
- Measure coil resistance: booster coil approximately 300 ohms, hold coil approximately 1000 ohms
- Inspect the gas valve relay on the main control board for signs of damage
- Observe through the lower access panel: igniter should glow orange, then gas should ignite within 15 seconds
Parts a technician may check or replace: Gas Valve Solenoid Coil Kit; Gas
Field note: Gas dryer valve coils are the most common cause of intermittent no-heat on Whirlpool, Maytag, and Amana gas dryers. The dryer lights initially, then the coils weaken and cannot hold the valve open. You will see the igniter glow repeatedly without gas ignition. The coil kit is inexpensive but this code specifically points to the relay, not the coils.
Safety note: If you smell gas that does not ignite within 30 seconds, turn off the gas supply valve and ventilate the room. Do not attempt to diagnose further without professional help.

How to troubleshoot the F4E3 error yourself#
Safety first on a gas appliance. If you smell unburned gas that does not light within a few seconds, turn off the gas supply valve, open windows to ventilate, and call a professional rather than diagnosing further. For the non-emergency pattern — heats then goes cold, igniter glowing without ignition — you can confirm the symptom but the repair is not a household job. The valve coils and the relay that drives them, and the safe testing of a gas train, belong to a technician. Do not disassemble the burner or valve yourself. Note the useful distinction: weak valve solenoid coils are the most common cause of intermittent no-heat on these dryers, but this specific code points at the relay side, and a technician will confirm which before fitting parts.
Is the Whirlpool Dryer F4E3 error worth fixing?#
F4E3 is a sensible repair on a gas dryer. Replacing the failed relay or the gas-valve solenoid coils, with the labor and safe testing a gas appliance demands, runs $130 to $350 installed. On a dryer worth keeping that is well below a new machine, and the coil kit itself is inexpensive. I would have this repaired by a technician rather than lived with, since a burner that heats intermittently wastes cycles and a gas fault is not one to ignore. Replacement only makes sense on an already-aging dryer near the top of the range.

Whirlpool Dryer F4E3: frequently asked questions#
What does F4E3 mean on a Whirlpool gas dryer?#
It is a gas-valve relay fault — the relay is not switching the burner reliably, so the dryer heats then goes cold and the igniter glows without lighting.
Is it safe to keep using the dryer with F4E3?#
If you smell gas that does not ignite, no — shut the gas valve and ventilate. Otherwise it under-dries and should be repaired promptly.
Can I clear F4E3 myself?#
No. Beyond shutting the gas valve if you smell gas, gas-valve and relay work is a technician job on a gas appliance.
How much does it cost to repair F4E3?#
From $130 to $350 for the failed relay or gas-valve solenoid coils, installed with the safe testing a gas dryer needs.
Which parts fail when a dryer throws F4E3?#
The gas-valve relay on the control board, or weak valve solenoid coils that can no longer hold the valve open.
Is a gas dryer with F4E3 worth repairing?#
Yes on a sound machine — a sub-$350 gas repair is well below a new dryer and resolves a heat fault you should not ignore.
Why does a gas-valve relay fault trigger F4E3?#
The relay must switch to open the gas valve on each heat call. When it fails to hold that circuit, the burner will not light or drops out, and the dryer raises F4E3.
