Whirlpool Refrigerator Error Code E5 — Ice Maker Sensor Fault
What this means
The E5 error code on Whirlpool refrigerators indicates a fault with the ice maker's internal thermistor — the temperature sensor that monitors the ice mold temperature and signals when it is time to harvest ice. When this sensor fails, the ice maker either stops producing ice entirely or produces partial, malformed cubes. This is one of the most common ice maker-related error codes on Whirlpool French door and side-by-side refrigerators.
Alternate codes: F5
Step-by-step fix
4 stepsReset the ice maker
Locate the ice maker in the freezer. Find the reset button (usually a small button on the bottom or side of the ice maker unit). Press and hold it for about 10 seconds until you hear a chime or the motor begins to cycle.
On some models, the reset is triggered by lifting and lowering the ice maker arm three times within 10 seconds.
Check the water supply to the ice maker
Verify that the water supply line to the refrigerator is connected and the valve is fully open. A restricted water supply can cause partial freezing and trigger sensor errors.
Check the water filter — a clogged filter can reduce water flow to the ice maker. Replace it if it has not been changed in 6 months.
Test the ice maker thermistor
Unplug the refrigerator. Access the ice maker unit by removing the ice bin and any screws securing the ice maker. Locate the thermistor (a small sensor probe on the ice mold) and test it with a multimeter. At freezer temperature (0°F), it should read within the expected range specified in the tech sheet.
The thermistor is integrated into many ice maker assemblies and cannot be replaced separately — if it has failed, the entire ice maker may need replacement.
Replace the ice maker assembly
If the thermistor is faulty, disconnect the ice maker's wire harness and water line. Remove the mounting screws and slide the ice maker out. Install the new ice maker, reconnect the water line and wire harness, and replace the ice bin.
After installing a new ice maker, allow 24 hours for the first batch of ice. Discard the first two batches to clear any manufacturing residue.
When to call a professional
If replacing the ice maker does not resolve the E5 error, there may be a main control board issue affecting the ice maker circuit. A technician can run diagnostic tests to identify the problem.
