Frequently Asked Questions
Common questions about Whirlpool E0 error
The E0 error on the Whirlpool WRS325SDHZ means the freezer compartment temperature sensor, or thermistor, is not providing valid readings to the control board. Without accurate temperature data, the refrigerator cannot regulate the freezer properly, posing a risk of food spoilage. A manual defrost or thermistor replacement is typically required.
The refrigerator may continue to run in a limited mode, but it cannot properly maintain safe freezer temperatures without a functioning sensor. Frozen food can begin to thaw if the error persists for several hours. Move frozen items to a backup freezer or cooler with ice while diagnosing the issue.
