Amana Refrigerator Error Code High Temp Alarm

The High Temp Alarm means the freezer exceeded 15°F for 2 hours or the fresh food compartment exceeded 60°F for 2 hours. The control system responds by illuminating the High Temp indicator, flashing the affected compartment indicator, and sounding an audible alarm. It is designed to alert you to a cooling problem before food spoilage becomes severe. Pressing the ALARM OFF key silences the alarm while you investigate the cause.

Pressing ALARM OFF silences the audible alert and clears the immediate alarm notification, but it does not resolve whatever caused the temperature rise. If the underlying problem is still present, the alarm will return once the compartment temperature again exceeds the threshold for 2 hours. A permanent resolution requires identifying and correcting the root cause, whether that is a component failure, airflow blockage, or door sealing issue.

Repair costs vary widely depending on the root cause. Replacing a thermistor is typically a lower-cost repair, often in the range of $75 to $200 including parts and labor. An evaporator fan motor replacement generally falls in the $100 to $300 range. Sealed system repairs involving refrigerant or compressor work are the most expensive, commonly ranging from $300 to $600 or more, and may make replacement of an older unit worth considering.

Start by pressing the ALARM OFF key to silence the alarm and then check for simple causes such as a door left open or a heavy load of warm food recently placed inside. If temperatures do not recover, inspect the evaporator fan for operation, check that vents are not blocked, and examine the door gaskets for damage. Persistent alarms after these checks point toward a thermistor failure, a defrost system problem, or a sealed system issue that may require professional diagnosis.

Food safety depends on how high temperatures climbed and for how long. The alarm triggers at 15°F in the freezer or 60°F in the fresh food compartment after 2 hours at those levels. Partially thawed freezer items that still contain ice crystals are generally considered safe to refreeze or use promptly. Refrigerated items that have been above 40°F for more than 2 hours, especially proteins and dairy, should be evaluated carefully using USDA food safety guidelines.
