Whirlpool Dryer F3E2 error code
F3E2 means the exhaust thermistor (the temperature sensor on the blower housing) has shorted. The control reads an impossibly high temperature, so it stops the cycle to protect the dryer.
Also shown as: F3E2, F3 E2, F23

What causes the F3E2 error?
- Shorted exhaust thermistor on the blower housing
- Pinched or melted sensor wires touching each other or metal
- Moisture or lint bridging the sensor terminals
- Control board misreading the sensor signal
- Note: on some top-load models this code maps to the moisture sensor instead
How to fix Whirlpool F3E2 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Power-reset the dryer
Unplug the dryer for 5 minutes, then plug it back in and try a cycle. A brief electrical glitch can produce a false shorted reading. - Clean around the sensor
Lint and moisture around the blower housing can bridge the sensor terminals and fake a short. With the dryer unplugged, remove the access panel and gently clean lint from around the thermistor.Safety warning: Always unplug the dryer before removing panels or touching wiring. - Inspect the sensor wiring (advanced)
With power disconnected, check the thermistor's wires for pinches, melted insulation, or terminals touching metal. At room temperature the thermistor should read about 10,000–12,000 ohms — a reading near zero confirms a short and the sensor needs replacing.Safety warning: Do not test resistance with the dryer plugged in. Use a multimeter on the ohms setting only with power disconnected.
When to call a technician
- The sensor tests shorted and replacement does not clear the code
- Sensor wiring is melted, chewed, or damaged inside the cabinet
- The control board is suspected of misreading a good sensor
- You are not comfortable using a multimeter or removing panels
Frequently asked questions
What is the difference between F3E1 and F3E2?
F3E1 means the exhaust thermistor circuit is open (no signal), while F3E2 means it is shorted (false high-temperature signal). Both stop heating and both usually end with replacing the same sensor.
My model manual says F3E2 is the moisture sensor. Which is right?
Both. Whirlpool reuses code numbers across platforms. On most front-load Duet-style dryers F3E2 is the exhaust thermistor shorted; on some newer top-load models it is the moisture sensor. Check your model's tech sheet.
Can I still dry clothes with F3E2 showing?
No — the dryer will not heat properly with a shorted sensor. Fix the sensor first.
