Which Replacement MaxxAir Circuit Board for Part # 4751k_Board_v1.4
Updated 01/05/2026 | Published 09/15/2024
Question:
All, I guess I ordered the wrong replacement board for my maxxair vent. I am trying to figure out the correct one, I have a 4751k_Board_v1.4 circuit board that is the only nomenclature I can find in regards to a model number. It does have the rain sensor and lift motor. I am not sure if this is the right one: https://www.etrailer.com/Accessories-and-Parts/MAXXAIR/MA10A04751KS.html or https://www.etrailer.com/Accessories-and-Parts/MAXXAIR/MA39FR.html I have no clue if the fan is reversible or not.
