| Code | What it means | Urgency | First safe check |
|---|---|---|---|
| F4 E4Also F4E4, L2 | Low or missing line voltageWhirlpool says F4 E4 can mean the electric dryer is not receiving the full line voltage its heater requires. The drum may still turn even when one side of the supply is unavailable. | Service recommended | Stop the dryer and identify its dedicated paired breakers without opening the appliance. |
| PFAlso Power Failure, PF error | Power failure interrupted the cycleWhirlpool says PF appears when a power failure interrupts the drying cycle. Clear or restart it once, then investigate if it returns without a known outage. | Check now | Confirm there is no electrical odor, damaged cord, hot plug, or repeatedly tripped breaker. |
| AFAlso Check Vent, Air Flow, AF code | Restricted exhaust airflowWhirlpool uses AF or Check Vent when the dryer detects restricted airflow. The lint screen, connector, exterior hood, or concealed exhaust run may be limiting air movement. | Pause and inspect | Stop the cycle and let the dryer cool. |
| F4 E3Also F4E3, AF, Check Vent | Restricted airflow or blocked ventWhirlpool identifies F4 E3 as restricted airflow. A clogged lint screen or vent, crushed connector, blocked outlet, or overly complex vent run can cause long drying and excess heat. | Pause and inspect | Stop the dryer and let it cool before inspecting airflow. |
How to use this index
Copy the display exactly
Spaces, letters, and lookalike characters matter. For example, 5E and SE may be easy to confuse on a segmented display.
Confirm the exact model
Error meanings and access instructions can vary by product family and model revision, even within one brand.
Start with observable checks
A code points to a system. It does not prove which part failed, so compare the symptom before replacing anything.
