Washer displays F3E2 and may not heat water properly during certain cycles.

Safety: Unplug the washer and shut off water supply before accessing internal components.

• Check water supply temperature: Ensure hot and cold hoses are not reversed and that hot water is actually hot at the faucet.
• Locate the thermistor: On many Amana models, the temperature sensor is mounted in the tub or integrated with the inlet valve assembly.
• Inspect wiring:
  • Access the rear or lower front panel.
  • Find the thermistor connector and check for corrosion, loose fit, or damaged wires.
  • Reseat the connector firmly.
• Test thermistor: Using a multimeter, measure resistance across the thermistor at room temperature and compare to the values in the tech sheet (typically around 10–50 kΩ depending on design). If open, shorted, or far out of range, replace it.
• Replace thermistor if faulty: Remove mounting screw or clip, install the new Amana-compatible sensor, reconnect wiring, and reassemble panels.

If the thermistor tests good and wiring is intact, the main control board may be at fault and should be evaluated by a technician.
