Frigidaire Freezer Error Code E8

E8 on a Frigidaire freezer with Precision Set Control means the temperature thermistor has shorted. The display will alternate between 'E8' and '-10°F' to indicate this fault. The thermistor is a resistive sensor that reports internal cabinet temperature to the control board, and a short causes its resistance to collapse to near zero, making accurate temperature monitoring impossible. The thermistor or its associated wiring must be inspected and repaired to resolve the error.

Operating the freezer with an active E8 code is not advisable for extended periods. Because the control board cannot read an accurate temperature from a shorted thermistor, it cannot regulate the compressor and cooling system correctly. This puts your frozen food at risk and may cause the compressor to run improperly. Address the fault as soon as possible to protect both your food and the appliance.

If the thermistor itself is shorted, the part is typically inexpensive, often in the range of $10 to $40 depending on the specific model. If the repair is performed by a technician, total costs including labor generally fall in the range of $75 to $200. Wiring harness repairs or connector cleaning may cost less if no parts are needed, while a control board replacement, if found to be at fault, would increase costs significantly.

A knowledgeable DIYer can diagnose this error by using a multimeter to measure the thermistor's resistance at the sensor terminals. If the thermistor reads near zero ohms, it needs to be replaced. If the sensor reads correctly, the wiring harness and connector between the thermistor and control board should be inspected for damage or corrosion. Thermistor replacement is generally a straightforward repair involving unplugging the old sensor and plugging in a new one.

Simply resetting the freezer by unplugging it and restoring power will not permanently clear E8 if the thermistor or wiring is still shorted. The control board will detect the fault again once it attempts to read temperature and the error will return. The underlying hardware problem must be corrected before the code will stay cleared.
