Amana Refrigerator rF — Refrigerator Compartment Thermistor Fault

Amana Refrigerator · Error code rF

What rF Means

The fresh-food compartment thermistor (temperature sensor) is reading out of range — open, shorted, or unrealistic value.

Symptoms

  • rF or rE shown
  • Fresh food too warm or freezing
  • Damper running constantly
  • No temperature control

Common Causes

1
Failed FF thermistor

Bead sensor open or out of calibration.

2
Pinched/cut thermistor harness

Wire damaged behind a drawer slide.

3
Failed main control board

ADC channel for sensor failed (rare).

How to Fix It

  1. Locate the thermistor (typically clipped to the upper-rear ceiling of the fresh-food compartment).
  2. Disconnect it and measure resistance: ~16 kΩ at 32°F is typical for this platform.
  3. Replace the thermistor if open, shorted, or far out of spec.
  4. Recheck cabinet temps over 24 hours.
