What E5 means on a Maytag refrigerator

The E5 error code on a Maytag refrigerator points to a problem within the ice maker system, specifically related to the ice mold thermistor. This thermistor monitors the temperature of the ice mold during the freeze and harvest cycle. When the control detects that the ice storage bin temperature is satisfied (meaning the bin is cold enough) but the ice mold has remained in a frozen state for an unusually long period, the E5 code is triggered. The most likely culprit is a faulty ice mold thermistor that is sending an inaccurate resistance reading to the control board.

The ice mold thermistor works by changing its electrical resistance in response to temperature changes. The control board uses these resistance readings to determine when the ice mold has reached the correct temperature to initiate a harvest cycle. If the thermistor is defective, shorted, or has drifted out of its specified resistance range, the board cannot accurately track the mold temperature. This can cause the mold to stay frozen far longer than intended, disrupting the normal timed cycle and triggering the E5 fault.

Diagnosing this code should begin with a physical inspection of the ice mold thermistor and its wiring harness. Check for any visible damage, corrosion on the connector pins, or broken wires. From there, use a multimeter to measure the thermistor resistance and compare the reading against the expected range for the ambient temperature. A reading that is open, shorted, or far outside the expected range confirms a failed thermistor. If the thermistor tests within spec, the control board or ice maker module should be evaluated.

Common causes of E5

  1. 01

    Faulty ice mold thermistor

    Part replacement

    The ice mold thermistor is the primary suspect for E5. If it has failed open or shorted, it will send an incorrect resistance signal to the control board, preventing the harvest cycle from initiating on time.

  2. 02

    Damaged or corroded thermistor wiring harness

    Wiring / connection

    The wiring connector between the thermistor and the control board can develop corrosion or loose pins, causing intermittent or incorrect resistance readings without the thermistor itself being defective. Inspect the connector for moisture damage and bent or pushed-back terminals.

  3. 03

    Ice maker module or control board issue

    Part replacement

    If the thermistor checks out within its expected resistance range and the wiring is intact, the ice maker module or main control board may be misinterpreting the thermistor signal. This would cause the board to incorrectly log an E5 condition.

  4. 04

    Ice maker assembly frozen up

    Wiring / connection

    Excessive frost or ice buildup around the ice mold can physically trap the mold in a frozen state, preventing normal harvest even when the thermistor and electronics are working correctly. Check for unusual frost accumulation around the ice maker compartment.

Frequently asked questions about E5

What does E5 mean on a Maytag refrigerator?
The E5 code on a Maytag refrigerator indicates a problem with the ice maker's ice mold thermistor. Specifically, the refrigerator has detected that the ice storage temperature is satisfied but the ice mold has remained in a frozen state longer than expected. This points to a thermistor that is not accurately reporting mold temperature to the control board, disrupting the harvest cycle.
How do I fix the E5 error on my Maytag refrigerator?
Start by inspecting the ice mold thermistor and its wiring harness for visible damage, corrosion, or loose connections. Use a multimeter to test the thermistor resistance and verify it falls within the expected range for the current temperature. If the thermistor reads open or shorted, it will need to be replaced. If the thermistor tests correctly, further diagnosis of the ice maker module or control board is needed.
Will resetting my Maytag refrigerator clear the E5 error code?
A reset may temporarily clear the E5 code, but it will return if the underlying issue with the ice mold thermistor or its circuit is not resolved. Resetting can be useful to confirm whether the fault is intermittent or consistent, but it is not a fix. The root cause needs to be diagnosed and corrected to permanently clear the code.
Is the E5 error on a Maytag refrigerator a safety concern?
The E5 error is specific to the ice maker system and does not affect the refrigerator or freezer compartment temperatures. Food stored in the refrigerator and freezer is not at risk due to this fault. However, leaving the issue unresolved may result in the ice maker stopping ice production entirely or cycling incorrectly over time.
How much does it cost to repair an E5 error on a Maytag refrigerator?
If the repair requires only an ice mold thermistor replacement, parts typically cost in the range of $15 to $50 depending on the specific model, with additional labor costs if a technician is hired. If the ice maker module or control board needs replacement, total repair costs can range from $100 to $300 or more for parts and labor. Getting a diagnosis first helps avoid replacing components unnecessarily.
