What does Amana Dryer F3 E1 Error Code - Causes & Fix mean?

F3 E1 means exhaust thermistor fault on Amana dryers. Power down 5 minutes, restart, and run a timed cycle to test the thermistor.

How do I fix Amana Dryer F3 E1 Error Code - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with F3 active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for Amana Dryer F3 E1 Error Code - Causes & Fix?

The most frequently replaced parts for Amana Dryer F3 E1 Error Code - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is Amana Dryer F3 E1 Error Code - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

Amana Dryer F3 E1 Error Code — What It Means

The F3 E1 code on an Amana dryer signals an exhaust thermistor fault. The exhaust thermistor monitors temperature in the exhaust air stream and reports back to the control board. When that sensor fails or its circuit opens, the dryer cannot safely regulate heat and throws F3 E1.

This is a dryer-only code. If you see F3 E1 on an Amana washer, it means something different (water-level detection), so always confirm you are looking at the dryer manual for your appliance.

Common Causes

Failed exhaust thermistor The thermistor itself has gone open, shorted, or is reading out of range.
Loose or corroded connector The plug between the thermistor and the wiring harness has backed out or developed corrosion.
Broken wire in the harness A wire running from the thermistor to the control board has been pinched, cut, or fatigued.
Control-board input failure The main control is not reading the thermistor signal correctly even when the sensor is good.

Step-by-Step Fix

Turn off the dryer at the circuit breaker and leave it off for a full 5 minutes to clear the control memory.
Restore power and start a new timed dry cycle (not an auto-sense cycle).
Run the dryer for 5 minutes and watch for the F3 E1 code to return.
If the code comes back, unplug the dryer and locate the exhaust thermistor (usually clipped to the exhaust duct near the blower housing or rear of the drum).
Disconnect the thermistor harness and test the thermistor with a multimeter for continuity or consult your model’s resistance table (the public Amana page does not list exact ohms).
Replace the exhaust thermistor if it reads open, shorted, or out of spec.
Inspect all wiring and connectors in the thermistor circuit for damage or corrosion, and repair or replace as needed before reassembling and testing.

Parts Often Needed

Part	Notes
Exhaust thermistor	Amazon \| Match the part number to your dryer model (usually printed on the cabinet or inside the door frame).
Dryer wiring harness (thermistor section)	Amazon \| Only if wires are cut, pinched, or connectors are damaged beyond cleaning.

When to Call a Pro

Call a technician if the code returns after you replace the thermistor and verify all connections are clean and tight. At that point the main control board may be failing to process the thermistor input correctly, and diagnosing control logic requires a service manual and model-specific test points. Also call a pro if you are uncomfortable working inside a 240 V dryer cabinet or if your model uses a thermistor assembly that is hard to reach without removing the drum.
