What Does Error Code F24 Mean on a Whirlpool Dryer?

Inlet/exhaust thermistor (temperature sensor) out of range.

F24 fires when the control board reads the inlet/exhaust thermistor resistance outside its expected window — typically because the sensor is open, shorted, or has drifted far from the roughly 10k-ohm room-temperature spec. Without a valid signal, the board cannot regulate drum temperature, so it flags the sensor rather than the heat source. This distinguishes F24 from cycling-thermostat or heater faults: the code points at the temperature-reading path, not at actual overheating or a failure to heat.

Models affected: Whirlpool electric and gas dryers that use a thermistor-based temperature sensing circuit, including models such as WED4815EW, WED5620HW, WED6620HW, and WGD4815EW

What owners report: Owners commonly report F24 appearing at cycle start or shortly into drying, sometimes after moving the dryer, which can unseat the thermistor connector. A quick reseat of the connector or a simple power cycle resolves some cases, but a persistent code usually traces back to the sensor itself.

What Causes Error Code F24?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

1

Thermistor open or shorted 60% of cases
2

Connector loose at the thermistor 20% of cases
3

Wiring damaged 12% of cases
4

Control board sensor input fault 8% of cases

How to Fix Whirlpool Dryer Error Code F24

🔧🔧 Moderate DIY Est. time: 30–60 min

⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.

1

Power cycle the dryer

Turn off the breaker for one minute, then restart.
2

Test the thermistor

Measure resistance against spec (about 10k ohms at room temperature); replace if open or shorted.

🔩 Multimeter 🔩 Whirlpool dryer thermistor ($15–$40)
3

Inspect the wiring

Reseat the connector and check the harness to the thermistor for damage.

⚠️ Unplug before testing.

How to Reset Error Code F24

Power down at the breaker for one minute. If F24 returns, test and replace the thermistor.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

If a new thermistor reads correctly but F24 persists, the control board sensor input has failed.

Average professional repair cost for this issue: $150–$280

Frequently Asked Questions

Can I keep using my Whirlpool Dryer when error F24 appears? +

You often can for a cycle or two, but the sensor issue behind F24 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.

What most commonly causes F24 on a Whirlpool Dryer? +

Across reported Whirlpool dryer repairs, the most frequent is thermistor open or shorted (60% of cases), connector loose at the thermistor (20%), then wiring damaged (12%). Check them in that order before replacing any parts.

F24 keeps coming back after a reset — what should I check next? +

A reset only clears the stored F24 fault; if it returns, the sensor problem is still present. Move on to the physical checks — power cycle the dryer, then test the thermistor — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.

How much does it cost to fix Whirlpool Dryer error F24? +

A DIY repair typically runs $15–$40 in parts, versus $150–$280 for a professional service call, so handling it yourself saves around $135. Expect the work to take roughly 30–60 minutes.

Which Whirlpool Dryer models show error F24? +

F24 is documented on Whirlpool electric and gas dryers that use a thermistor-based temperature sensing circuit, including models such as WED4815EW, WED5620HW, WED6620HW, and WGD4815EW. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
