Encountering the F3 E3 error code on your Whirlpool Cabrio Steam dryer signals a critical issue with the appliance’s inlet thermistor. This specific code definitively points to an open or shorted inlet thermistor circuit, indicating that the dryer is unable to accurately sense incoming air temperature. Such a malfunction prevents proper operation and often leads to the dryer shutting down prematurely or failing to start cycles.
Potential Triggers for Your F3 E3 Error
- A faulty or failed inlet thermistor component.
- Damaged wiring or loose connections leading to the inlet thermistor.
- Moisture or debris affecting the thermistor’s sensor.
- Infrequently, a main control board issue, though less common with F3 E3.

A Step-by-Step Guide to Fixing F3 E3
- Disconnect Power: For your safety, begin by unplugging the dryer from the wall outlet or by switching off the dedicated circuit breaker. This crucial step prevents electrical shock during the repair process.
- Access the Thermistor: Depending on your specific Whirlpool Cabrio Steam model, accessing the inlet thermistor may involve removing the top panel, rear panel, or front panel. Consult your dryer’s service manual or a diagram for the precise location. The inlet thermistor is typically situated near the air inlet duct.
- Locate and Disconnect: Once you’ve found the inlet thermistor, carefully disconnect its wiring harness.
- Test Resistance: Using a multimeter, measure the resistance across the thermistor’s terminals. At room temperature (approximately 77°F or 25°C), a healthy inlet thermistor should read around 49,000 ohms (49 kOhms). Significant deviations from this value, such as an open circuit (OL) or a very low resistance reading, confirm a faulty thermistor.
- Inspect Wiring: While the dryer is disassembled, take a moment to visually inspect the wiring leading to the thermistor for any signs of damage, fraying, or loose connections. Repair or replace any compromised wiring.
- Replace if Faulty: If your resistance test indicates the thermistor is out of specification, it must be replaced. Install the new inlet thermistor, ensuring all connections are secure.
- Reassemble and Test: Reassemble the dryer panels in reverse order. Plug the dryer back in and run a test cycle to confirm the F3 E3 error has been resolved.
