Sharp Microwave Error Code EE24

EE24 indicates that the control board has detected fan motor 2 (the MG2 cooling fan) as locked or not running. This fan cools the magnetron tube, and the microwave shuts down when it is not operating to prevent serious internal damage from overheating. The fault requires inspection of the fan motor, its wiring, and related components before normal operation can resume.

No. The EE24 code means the magnetron cooling fan is not running, and the microwave has disabled itself for this reason. Attempting to force operation without a functioning cooling fan risks overheating and permanent damage to the magnetron, and in extreme cases could create a fire or burn hazard. Do not use the appliance until the fault is resolved.

Repair cost depends on the root cause. A fan motor replacement typically falls in the range of $50 to $150 in parts, plus labor if a technician performs the work. Wiring repairs are generally on the lower end of the cost range, while a control board replacement can run $100 to $250 or more in parts alone. Given that microwave repair involves high-voltage components, professional service is recommended for most homeowners.

Unplugging the microwave for several minutes may temporarily clear the code, but EE24 will return if the underlying cause is not corrected. Because the fault is tied to a real hardware condition, a reset alone is not a fix. The fan motor and its circuit need to be physically inspected and repaired.

Start by disconnecting power and inspecting fan motor 2 for any visible obstructions, debris, or grease buildup on the blade. If the fan is clear, test the motor windings for continuity and check the wiring harness for damaged or corroded connections. If the motor has failed or the wiring is damaged, those components will need to be replaced. If both check out correctly, the control board may need evaluation by a qualified technician.
