What E5 means on a Electrolux ice maker

The E5 error code on an Electrolux ice maker indicates that Thermistor 1 is reading a temperature that is more than 10 degrees Fahrenheit above the setpoint for a sustained period. Specifically, the fault triggers when the actual temperature exceeds the setpoint by 10°F for more than 6 hours, and the code is logged when that out-of-range condition persists for more than 12 hours total. Thermistor 1 is a negative temperature coefficient (NTC) sensor responsible for monitoring a primary temperature zone within the ice maker, and its readings directly govern the control board's ability to regulate the refrigeration cycle.

When the thermistor reports temperatures significantly higher than the target setpoint for this duration, it typically indicates one of two broad categories of failure: a problem with the sensor itself (open circuit, shorted circuit, or drift in resistance values), or an actual thermal condition where the ice maker compartment is genuinely running too warm. A failed thermistor may send incorrect resistance values to the control board, causing the board to interpret the compartment as warmer than it actually is. Alternatively, a real warm condition can result from a refrigerant issue, condenser problem, or blocked airflow.

Diagnosing E5 requires distinguishing between a faulty sensor and an actual thermal performance problem. Technicians should check the thermistor resistance at a known temperature and compare it to the expected NTC curve. If resistance values are out of specification, the thermistor requires replacement. If resistance checks out, attention should shift to the refrigeration system, including condenser coil condition, fan motor operation, and ambient temperature conditions around the unit.

Common causes of E5

  1. 01

    Faulty Thermistor 1 (temperature sensor)

    Part replacement

    The thermistor may have drifted out of its correct resistance range or failed entirely, causing the control board to receive inaccurate temperature readings. Testing the sensor with a multimeter and comparing resistance to the expected NTC values at a known temperature will confirm this.

  2. 02

    Dirty or blocked condenser coils

    Wiring / connection

    Dust and debris buildup on the condenser coils reduces heat dissipation efficiency, causing the unit to run warmer than the setpoint. Inspect and clean the condenser coils as a first physical check.

  3. 03

    Condenser or evaporator fan motor failure

    Part replacement

    If a fan motor has failed or is running below speed, airflow across the coils is reduced and temperatures inside the unit will rise above setpoint. Check fan motor operation and listen for abnormal noise or no operation.

  4. 04

    Refrigerant leak or low refrigerant charge

    Part replacement

    A loss of refrigerant reduces the system's ability to absorb heat, resulting in sustained high temperatures inside the compartment. This requires a certified technician to diagnose and repair.

  5. 05

    High ambient temperature or poor ventilation around the unit

    Wiring / connection

    If the ice maker is installed in a location with excessive ambient heat or restricted clearance for ventilation, it may be unable to maintain the setpoint temperature. Verify the installation environment meets the recommended clearance and ambient temperature specifications.

Frequently asked questions about E5

What does E5 mean on a Electrolux ice_maker?
E5 indicates that Thermistor 1 is reading a temperature more than 10°F above the setpoint for an extended period, specifically more than 6 hours of continuous out-of-range readings and more than 12 hours overall. The code points to either a failed temperature sensor or a genuine thermal performance issue within the ice maker. The unit may stop producing ice or produce it at a reduced rate while this fault is active.
Can I fix the E5 error myself, or do I need a technician?
Some causes of E5, such as dirty condenser coils or poor ventilation, can be addressed without professional help. However, if the thermistor itself has failed, replacing it requires identifying the correct replacement part and basic disassembly skills. If the refrigerant system is involved, a certified technician is required by law to handle refrigerant. Start with simple checks like cleaning the condenser and verifying airflow before calling a professional.
Is it safe to keep using my ice maker when E5 is displayed?
Continuing to use the ice maker while E5 is active is not recommended. If the unit is genuinely running too warm, ice quality and food safety could be compromised. Ice produced under high-temperature conditions may be malformed, cloudy, or melt quickly, and bacterial growth risk increases in warm water-handling components. It is best to address the fault before relying on the unit for regular use.
How much does it cost to repair an Electrolux ice maker E5 error?
Repair costs vary depending on the root cause. Replacing a thermistor sensor is typically a lower-cost repair, with parts generally ranging from $20 to $80 and labor adding $75 to $150 depending on your area. If the refrigerant system requires service, costs can rise significantly, often ranging from $200 to $500 or more. Condenser cleaning is the least expensive fix and may cost little to nothing if done yourself.
Will resetting my Electrolux ice maker clear the E5 error code?
A reset may temporarily clear the E5 code from the display, but the fault will return if the underlying cause is not corrected. Because the code requires the out-of-range condition to persist for 6 to 12 hours before triggering, it may take some time after a reset for the error to reappear if the problem is still present. Resetting without diagnosing and fixing the root cause is not a permanent solution.
