Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the dryer before removing any panels.
- Locate inlet thermistor: On some Amana models, an inlet thermistor is mounted near the heater housing or air inlet.
- Inspect and test: Disconnect the thermistor and check its resistance at room temperature with a multimeter. Compare to the specified value in the tech sheet. Replace if out of range, open, or shorted.
- Check wiring: Inspect the harness from the thermistor to the control board for damage or loose connections.
- Reassemble and test: After replacing or reseating components, restore power and run a test cycle to confirm the F8 code is cleared.
