Troubleshooting MaxxAir 7000K Not Operating Properly With New Lift Motor and Circuit Board  

Updated 02/03/2026 | Published 07/01/2024

Question:

I have a replacement motor and circuit board for my maxxair 7000k. I’m replacing with the parts below but my fan will not work. It basically tries to close the lid and spins up the fan. Once the lid is closed it stops and won’t do anything else.

I do see the Lift Motor # MA10-20270 and Circuit Board # MA10A21275K are the correct units for your MaxxFan Deluxe Roof Vent # MA00-07000K. I would start by checking the wiring and voltage going to your vent fan and 90% of the time the issues with this vent has to do with either over or under voltage. You will want to use a Multimeter # PT89ZR to also test the voltage when operating the fan to determine if the voltage is dropping to much when the fan starts to turn.

Hey, how did things go after you checked the wiring and voltage on your MaxxFan Deluxe vent? Were you able to get the fan running properly once you tested it with the multimeter? Your update could make it easier for the next person troubleshooting the same issue.
