Electrolux Ice Maker Error Code E2

Thermistor 1 is shorted.

Electrolux codesElectrolux ice maker codes

Thermistor 1 is shorted.

First step from the service manual

Replace thermistor. Check for thermistor errors by accessing service mode option 'View thermistor # status' (options 19, 20, or 21). If the error code is repeated, the thermistor is open or shorted. If a temperature is displayed, the thermistor is not defective.

What E2 means on a Electrolux ice maker

The E2 error code on an Electrolux ice maker indicates that Thermistor 1 has shorted. A thermistor is a temperature-sensing resistor whose resistance changes predictably with temperature. The ice maker's control board monitors this resistance continuously to track temperatures at a specific location in the refrigeration or ice-making system. When the resistance drops to an abnormally low level, consistent with an internal short circuit, the control board interprets this as an invalid reading and triggers the E2 fault to alert the technician.

A shorted thermistor differs from an open thermistor in that the resistance collapses rather than breaks the circuit entirely. Both failure modes prevent accurate temperature measurement, which can cause the ice maker to behave erratically, halt ice production, or shut down as a protective measure. Thermistor 1 specifically refers to the first temperature sensor in the unit's sensing array, and its precise location may vary by model.

Diagnosing this fault involves entering the service mode and navigating to options 19, 20, or 21 to view the thermistor status directly. If the display repeats the error code, the thermistor is confirmed as open or shorted. If the display shows an actual temperature reading, the thermistor itself is functioning correctly and the fault may be intermittent or related to wiring and connections rather than the sensor component itself.

Common causes of E2

  1. 01

    Failed thermistor with internal short

    Part replacement

    The thermistor itself has developed an internal short circuit, causing its resistance to collapse. This is the most common cause of E2 and is confirmed when the service mode options 19, 20, or 21 repeat the error code rather than displaying a temperature.

  2. 02

    Damaged or pinched thermistor wiring

    Wiring / connection

    The wiring harness connecting the thermistor to the control board may be pinched, chafed, or shorted against the unit's chassis. Inspect the wire routing for any visible damage or contact points that could cause the two conductors to short together.

  3. 03

    Corroded or contaminated connector

    Wiring / connection

    Moisture intrusion into the thermistor connector can cause corrosion that bridges the terminals and mimics a short circuit. Inspect the connector for discoloration, moisture, or corrosion deposits and clean or replace as needed.

  4. 04

    Control board fault misreading thermistor input

    Part replacement

    In rare cases, the control board's input circuit for the thermistor signal may have failed, causing it to read a valid thermistor as shorted. This is suspected only after the thermistor and all wiring have been confirmed good through service mode testing.

Frequently asked questions about E2

What does E2 mean on a Electrolux ice_maker?
The E2 code means Thermistor 1 has shorted. The control board monitors the resistance of this temperature sensor and triggers E2 when it detects an abnormally low resistance consistent with a short circuit. This prevents the unit from reading temperatures accurately, which can halt ice production. The fault is confirmed or ruled out by checking thermistor status through the service mode.
How do I fix an E2 error on my Electrolux ice maker?
Start by entering the service mode and checking the thermistor status using options 19, 20, or 21. If those options repeat the error code, the thermistor is confirmed as defective and should be replaced. If a temperature is displayed instead, inspect the wiring harness and connector for damage, pinching, or corrosion before replacing any parts.
Will resetting my Electrolux ice maker clear the E2 error?
A reset may temporarily clear the E2 error from the display, but the fault will return if the underlying thermistor short has not been resolved. Because the control board continuously monitors thermistor resistance during operation, a shorted thermistor will trigger the code again as soon as the unit restarts its diagnostic cycle.
Is it safe to continue using my ice maker when E2 is displayed?
It is not recommended. When Thermistor 1 is shorted, the control board loses accurate temperature data for that sensor location. Continued operation without a functioning thermistor can result in improper cooling cycles and ice that does not meet safe temperature standards. It is best to stop using the unit for ice production until the fault is repaired.
How much does it cost to fix an E2 error on an Electrolux ice maker?
If only the thermistor needs replacement, parts typically cost in the range of $10 to $40 depending on the specific model. If professional service labor is required, the total repair cost including diagnostics and labor commonly falls in the range of $80 to $200. A control board replacement, if needed, would increase costs significantly beyond that range.
