Electrolux Ice Maker Error Code E1

The E1 code means that Thermistor 1 is open, indicating the temperature sensor circuit is broken and sending no valid signal to the control board. The ice maker relies on this sensor to monitor temperatures and control the freeze and harvest cycles. Without a working thermistor, the unit will not operate normally. The fault must be diagnosed and repaired before ice production can resume.

A reset may temporarily clear the E1 code from the display, but if the underlying problem persists the error will return. The service mode check is the reliable way to confirm whether the thermistor is actually defective. If service mode displays a valid temperature rather than repeating the error, the condition may have been intermittent. A confirmed open thermistor will not be resolved by resetting alone.

If only the thermistor needs replacement, parts typically range from around $15 to $60 depending on the specific model and supplier. If a professional technician performs the repair, total costs including labor generally fall in the range of $100 to $250. Costs can be higher if damaged wiring or a harness also needs to be replaced. Getting a diagnostic visit estimate beforehand is recommended.

A knowledgeable DIYer can diagnose the E1 error by accessing the service mode and using options 19, 20, or 21 to check the thermistor status. If the error repeats in service mode, the thermistor or its wiring needs attention. Replacing the thermistor is a relatively straightforward repair, but working inside the ice maker requires disconnecting power and comfort with appliance wiring.

It is not advisable to continue using the ice maker while an E1 error is active. The unit depends on Thermistor 1 to regulate the freeze cycle accurately, and operating without valid temperature data can lead to improper ice production or stress on other components. The machine will typically halt normal operation on its own when this fault is detected. Address the thermistor fault before resuming use.
