Electrolux Ice Maker Error Code E8

The E8 code on an Electrolux ice maker indicates that Thermistor 3 has been detected as open or shorted. This means the control board is reading a resistance value from that temperature sensor that falls outside the acceptable range. The fault can originate from the sensor itself, the wiring, or the connector. The ice maker may suspend operation until the issue is resolved.

Continuing to run the ice maker with an active E8 fault is not recommended. The control board depends on Thermistor 3 to regulate the freezing cycle accurately, and operating without reliable temperature data can lead to improper cooling, water leaks, or damage to other components. It is best to address the fault before resuming normal use.

A reset may temporarily clear the E8 code, but it will return if the underlying fault with Thermistor 3 or its wiring is not corrected. Resetting does not repair a failed sensor, damaged wire, or corroded connector. Use a reset only as a first step to confirm the fault is consistent, then proceed with proper diagnosis and repair.

A knowledgeable DIYer can attempt to diagnose the E8 error by inspecting the Thermistor 3 wiring harness and connector for visible damage, corrosion, or loose pins. If you have a multimeter, you can test the thermistor resistance and compare it to the expected value at a known temperature. Replacing the thermistor is a straightforward parts swap in most cases, but tracing wiring faults or replacing the control board may require more technical experience.

Repair costs depend on the root cause. Replacing a thermistor sensor is typically the least expensive fix, with parts generally ranging from $10 to $40 and professional labor adding $75 to $150. If the control board is at fault, parts alone can range from $80 to $250 or more, plus labor. Cleaning or reseating a corroded connector may cost nothing beyond your time if no parts are needed.
