Amana Refrigerator Error Code High Temperature Alarm

The High Temperature Alarm means the freezer has risen above -9°C or the refrigerator section has risen above 15.5°C, and the elevated temperature has persisted for at least two hours. Both an audible alarm and an indicator light activate to alert you to the condition. It signals that the unit is not maintaining safe food storage temperatures and the cause should be investigated promptly.

Pressing the Alarm Off pad will silence the alarm sound, but the indicator light will remain on until the compartment actually cools back down to a safe temperature. Resetting the alarm does not fix the underlying cause if there is a mechanical or component failure present. The alarm will reactivate if the temperature rises again after cooling down.

Repair costs vary widely depending on the root cause. Cleaning condenser coils or adjusting a door gasket can cost very little, while replacing an evaporator fan motor typically ranges from $100 to $250 in parts and labor. A defrost system repair involving a heater or thermostat generally falls in the $150 to $350 range. Sealed system repairs such as refrigerant recharge or compressor replacement are the most expensive, often ranging from $300 to $700 or more.

Start by pressing the Alarm Off pad to silence the audible alert. Then check for obvious causes such as a door left open, blocked vents, or dirty condenser coils. If the unit returns to proper temperature on its own, the indicator light will turn off. If temperatures do not recover, further diagnosis of the defrost system, evaporator fan, or sealed refrigeration system is needed.

Food safety depends on how long temperatures were elevated and how high they reached. Freezer items that have partially thawed should be evaluated carefully, and any items that have fully thawed and remained above safe temperatures for extended periods should be discarded. Refrigerator items exposed to temperatures above 4°C for more than two hours are generally considered at risk according to standard food safety guidelines. When in doubt, discard perishable items to avoid foodborne illness.
