Frigidaire Refrigerator Error Code E8

The E8 error code on a Frigidaire refrigerator indicates that one or more temperature sensors in the unit are detecting an out-of-range or faulty reading. Temperature sensors, also called thermistors, are resistive components that change their electrical resistance in response to temperature changes. The refrigerator's control board continuously monitors these resistance values to track compartment temperatures and regulate the compressor, fans, and defrost system. When a sensor reading falls outside the expected parameters, the E8 code is triggered and an audible alarm sounds.

The sensors involved in this error can be located in the fresh food compartment, the freezer compartment, or in positions such as the evaporator or defrost areas depending on the specific model. A faulty thermistor may present as an open circuit, a short circuit, or an intermittent reading that does not correspond to actual compartment temperatures. Wiring harness issues, such as corroded connectors or damaged insulation, can produce the same symptom by disrupting the signal between the sensor and the control board.

Because this error can involve multiple possible sensor locations and requires reading resistance values to properly diagnose, professional service is recommended. The initial step is to press the Alert Reset button to silence the alarm while you assess whether temperatures in the compartments appear normal. If temperatures are outside the safe range or the code returns after resetting, contact Frigidaire support at 1-800-374-4432 to arrange authorized service.
