What F3E3 Means
Maytag names F3E3 as the inlet thermistor. This sensor watches the temperature of the air entering the drum, and the control uses it alongside the exhaust sensor to manage the heater. A reading outside the expected range stops the cycle.
Common Causes of F3E3
- Restricted airflow skewing inlet temperature
- Inlet thermistor failed
- Wiring to the thermistor damaged
- Control board misreading the sensor
🔧 One Safe Check You Can Try
Check the lint screen and the vent first, since restricted airflow skews both inlet and exhaust temperatures. Unplug the dryer for five minutes, restore power and run a short timed cycle. If the code comes back on a clear vent, the sensor or its wiring needs testing inside the cabinet, which is a service call. Note whether the dryer heats at all before the code appears, because a machine that heats briefly then faults behaves differently from one that never heats, and that distinction saves diagnostic time.
⚠ Why You Shouldn't Go Further Than That
- The sensor sits inside the cabinet beside mains wiring, and near the burner on a gas model.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
