F3E1
May need a pro

The exhaust thermistor measures the temperature of the air leaving the drum so the control can manage the heat. F3E1 means the control is getting an impossible reading from it, usually because the sensor has failed open or shorted, or a wire to it is loose or damaged.

Whirlpool doesn't publish a model list for this code; it appears on Whirlpool dryers with a digital display. Check your owner's manual.

Also shown as

Older Cabrio and Maytag Bravos dryers show F-22 or F-23 for an exhaust thermistor failure; Duet dryers show F:22 or F:23 and call it the outlet thermistor. Maytag Centennial dryers also use F3 E1.

Difficulty

Try the basic checks, but the usual fix is a technician's job.

Safety first: unplug the dryer (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Whirlpool F3E1

  1. Reset the dryer

    Switch off the dryer's breaker(s), or unplug it, for 1 minute. Restore power, start a Timed Dry cycle, and watch for about 1 minute to see if the code returns.

  2. Clean the lint screen and check the vent

    With the dryer unplugged, clean the lint screen and make sure the vent behind the dryer is not crushed or packed with lint. This won't fix a failed sensor, but heavy lint near hot parts is a fire risk, so it's worth doing before a technician visit.

When to call a technician

If the code returns, the exhaust thermistor or its wiring needs testing inside the cabinet, so book a technician. On a gas dryer, if you ever smell gas, leave the house right away and call your gas company from outside.
