Amana Refrigerator Error Code LO
Low temperature alert - freezer too cold
Common Causes
- 1Temperature set too low
- 2Thermistor drift
- 3Control board fault
Step-by-Step Troubleshooting
- 1
Adjust the freezer temperature to the recommended 0F (-18C)
- 2
Place a standalone thermometer in the freezer to verify actual temperature matches the display
- 3
If the actual temperature is normal but the alarm sounds, the thermistor may be drifting — check resistance
- 4
Clean the condenser coils if the unit is overcooling (coil dust can cause erratic temperature cycling)
Pro Diagnostic Tip
On Amana top-freezer models, LO occasionally triggers when the freezer sensor drifts with age. Verify with an external thermometer. If the sensor reads accurately but the display is wrong, the control board needs replacement. If the sensor reads inaccurately, replace the thermistor — it is the same part used across the Whirlpool platform.
