What Does Error Code F22 Mean on a Whirlpool Dryer?

Outlet thermistor failure.

F22 fires when the control board reads the outlet (exhaust) thermistor as out of its expected resistance range — typically an open or shorted circuit rather than a plausible temperature value. Because the board relies on this sensor to regulate the heating cycle, it halts or limits heat and flags the fault. This differs from F30/F31, which point to the inlet thermistor or its circuit; F22 isolates the fault to the exhaust-side sensor or its wiring.

Models affected: Whirlpool electric and gas dryers with an outlet thermistor, including models such as WED4815EW, WED5620HW, WED6620HW, and WGD4815EW

What owners report: Owners commonly report F22 appearing shortly after startup or when a cycle won't heat properly, sometimes intermittently as the dryer warms. A loose or heat-degraded connector at the thermistor is a frequent false trigger, and reseating that plug before replacing the sensor is a quick win many find worthwhile.

What Causes Error Code F22?

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 70% of cases
2

Thermistor wiring connector loose 20% of cases
3

Damaged wiring from heat exposure 10% of cases

How to Fix Whirlpool Dryer Error Code F22

🔧🔧 Moderate DIY Est. time: 30–60 min

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

1

Locate the thermistor

The outlet thermistor is typically located in the exhaust duct inside the dryer cabinet.
2

Test resistance

At room temperature: approximately 10,000–12,000 ohms. Test with a multimeter.

🔩 Multimeter
3

Replace thermistor

Disconnect connector and remove sensor mounting screw. Install new sensor.

Frequently Asked Questions

Can I keep using my Whirlpool Dryer when error F22 appears? +

You often can for a cycle or two, but the sensor issue behind F22 will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.

What most commonly causes F22 on a Whirlpool Dryer? +

Across reported Whirlpool dryer repairs, the most frequent is thermistor open or shorted (70% of cases), thermistor wiring connector loose (20%), then damaged wiring from heat exposure (10%). Check them in that order before replacing any parts.

F22 keeps coming back after a reset — what should I check next? +

A reset only clears the stored F22 fault; if it returns, the sensor problem is still present. Move on to the physical checks — locate the thermistor, then test resistance — 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 F22? +

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 F22? +

F22 is documented on Whirlpool electric and gas dryers with an outlet thermistor, 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.
