Frigidaire Freezer Error Code high temp

The high temp alert means the freezer's temperature monitoring system has detected that the interior temperature has risen to an unsafe level for frozen food storage. It is triggered by the unit's temperature sensor when conditions inside the cabinet exceed the acceptable threshold. The alarm can be silenced by pressing the 'set' button next to the 'alarm off' indicator or by pressing any key on the control panel. Silencing the alarm does not fix the underlying problem, so further investigation is needed if the unit does not recover its temperature.

Food safety depends on how high the temperature rose and for how long. The USDA recommends that frozen food kept at 40 degrees Fahrenheit or below is generally still safe. If the freezer temperature climbed above 40 degrees for more than two hours, perishable items may need to be discarded. Check for ice crystal presence in previously frozen items as a general indicator of whether full thawing occurred.

Repair costs vary widely depending on the cause. Replacing a door gasket is typically the least expensive fix, often in the range of $20 to $75 for the part. Replacing an evaporator fan motor or defrost components generally falls in the $50 to $200 range for parts, plus labor if a technician is involved. A refrigerant leak or compressor failure represents the most costly repair, with total costs potentially ranging from $200 to $600 or more depending on the unit and service rates in your area.

Start by checking the basics: confirm the door is fully closed, inspect the door gasket for damage, and verify the freezer is plugged in and the circuit breaker has not tripped. If those checks pass, listen for the evaporator fan and monitor whether the unit cools back down to its set temperature over the next few hours. If the temperature continues to rise or the unit never recovers, a component such as the evaporator fan motor, defrost heater, or defrost thermostat may need to be tested and replaced.

Pressing any key or the 'set' button will silence the audible alarm, but this does not reset the root cause. If the underlying issue, such as a failed fan, defrost component, or open door, is not corrected, the alert will return once temperatures rise again. The alarm will typically clear on its own once the freezer returns to a safe operating temperature after the cause is resolved.
