BRUSH - DRIVE MOTOR (Mitsubishi MB290422K000)

A worn drive motor brush can cause intermittent power loss or arcing inside the motor housing. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB290422K000. The brush is a carbon block that slides against the motor commutator to conduct electrical current. Over time, the brush wears down and reduces contact pressure, leading to poor motor performance. If the brush becomes too short, the motor may fail to start or run erratically. The item ships at approximately 0.122 pounds. Verify the serial number or application, then call (562) 693-7748.
