Replacement Circuit Board For 2018 Minnie Winnie With MaxxFan 4700K
Updated 09/26/2025 | Published 04/19/2025
Question:
Hello I hope someone can help me. I have a 2018 Minnie Winnie with an out of control Maxxfan. I disassembled it to get to the circuit board in hopes of replacing it. There is no serial number visible on any of the parts other than the circuit board which has 4700K_Board _V1.6 and H112907D stamped on it. Can you determine what replacement circuit board I need? Thanks so much!
