How to fix Whirlpool Duet hybrid dryer error code F4 E3 (safe owner checks)

Safety first: disconnect power before you remove any panel or reach into the sump or drum. Do not touch wiring, the control board or the motor. If you see water near electrical parts, stop and call a technician. These steps are based on the Whirlpool Duet hybrid dryer error-code chart (via Sears PartsDirect) [1], rewritten for clarity.

Write down the code and model number. Note exactly what the display shows (F4 E3) and copy the full model number from the rating label, so you can confirm this chart applies to your duet hybrid dryer and order the right parts.
Clean the filter. Clean the lint filter and the secondary lint filter.
Check the exhaust fan. Check the exhaust fan.
Do a power reset. Unplug the appliance or switch off its breaker for one minute, then restore power and try again. If the code clears and stays away, it may have been a one-off fault.
Test and decide. Run a short cycle or restart and watch the display. If F4 E3 comes back after these checks, stop using the dryer for this function and call a technician, because the remaining causes need meters or part replacement.

The first and last steps (and the power reset) are general owner checks added by ErrorCodePro; the rest follow the Whirlpool Duet hybrid dryer error-code chart published by Sears PartsDirect, rewritten for safe owner use.
