The Mitsubishi Electric T7WA03371 Heat Sink is an OEM thermal-management component used with the power board assembly in compatible Mitsubishi Electric MXZ multi-zone outdoor units.
The T7WA03371 is identified as a Heat Sink – Power Board and is used in applications including MXZ-3C24, MXZ-3C30, and MXZ-4C36 series equipment. Its primary function is to transfer heat away from the power electronics, helping maintain proper operating temperatures within the outdoor unit's electrical section.
When servicing a Mitsubishi mini-split or MXZ multi-zone heat pump, technicians should inspect the heat sink mounting surfaces, fasteners, associated power board, and specified thermal interface material. Proper thermal contact between the electronic components and heat sink is important for effective heat dissipation.
Always verify the complete Mitsubishi outdoor-unit model, serial number, and original part number before ordering.
