Bosch Refrigerator Error Code 3-4-9

Error code 3-4-9 indicates a fault with the ice maker's crusher solenoid. The crusher solenoid controls the mechanism that switches between cubed and crushed ice. The refrigerator's control board has detected an abnormal electrical condition from this component. Ice dispensing may be impaired until the issue is resolved.

A reset may temporarily clear the code from the display, but if the underlying fault with the crusher solenoid or ice maker is not repaired, the code will return. Resetting without addressing the root cause is not a fix. The solenoid or wiring must be inspected and repaired or replaced to resolve the error permanently.

Repair costs depend on whether only the crusher solenoid needs replacement or the entire ice maker assembly is required. Solenoid replacement is generally the lower-cost option, while a full ice maker assembly replacement will be more expensive. Combined parts and labor costs typically range from around $150 to $400 or more depending on your location and the specific parts needed.

Start by testing the crusher solenoid with a multimeter to check for an open circuit, short, or abnormal resistance. If the solenoid is faulty, replace it. If the solenoid tests within normal parameters, the next step is to replace the ice maker assembly. Also inspect the wiring harness and connectors between the solenoid and the control board for damage or corrosion.

This fault code relates specifically to the ice maker's crusher solenoid and does not indicate a risk to food safety or a fire hazard under normal circumstances. The refrigerator's cooling functions should remain unaffected. However, the ice dispenser may not operate correctly until the fault is addressed, so prompt repair is recommended.
