On Whirlpool and Maytag dryers, F3E1 points to the exhaust thermistor, F3E3 to the inlet thermistor, F5E1 to the door switch, F1E1 to the main control, F6E2 to a communication fault and PF to a power interruption. Clean the lint screen and vent, check the breaker and unplug for 5 minutes first; thermistor, control and communication codes that return need a technician.
| Code | What it means | What you can do |
|---|---|---|
| F3E1 | Exhaust thermistor reading abnormal | Clean the vent first; repeats mean the thermistor or wiring. |
| F3E2 | Meaning varies by model — sources give different definitions (exhaust thermistor or moisture sensor) | Model-specific: a technician visit is needed to find the exact cause. |
| F3E3 | Inlet thermistor open or shorted | Technician repair. |
| F5E1 | Door switch problem — door state can't be confirmed | Close firmly; repeats mean the switch. |
| F1E1 | Main control fault | Unplug 5 minutes; repeats need a control board. |
| F6E2 | Communication error between controls | Unplug 5 minutes; repeats need diagnosis. |
| PF | Power interruption during the cycle | Press Start to resume; frequent PF means a supply or outlet problem. |
Codes and their meaning can vary by model and production year, and the same code can have different causes. Where sources disagree we say so; in every case the exact cause is confirmed only by a technician's on-site diagnosis. Your owner's manual has the definitive list for your model.
Unplug the appliance (or switch off its breaker) before touching anything inside it, and never open a sealed refrigeration system, a gas valve or a microwave. If a code points to a part, the part has to be tested before it is replaced; we do that on the $75 diagnostic visit, credited toward the repair.
The exhaust temperature sensor is reading out of range — often after overheating from a clogged vent.
Power failure: the cycle was interrupted. Press Start to continue.
Yes. Overheating from restricted airflow is a common trigger for thermistor codes.
