Question:

My Max Air fan will not open or close. What would cause this?

asked by: Christopher H

Expert Reply:

The two most likely causes of a MaxxAir vent fan lid not opening or closing are either going to be a lift motor or operator failure. I recommend removing the motor and applying power directly to this to see if the shaft turns. If not, you know the motor is bad and needs to be replaced for which we have the Replacement Lift Motor for Maxx Fan Plus Roof Vent part # MA10-20270. If the motor works properly then it's most likely a bad operator for which we have the Replacement Operator Mechanism part # MA10-20281K-1AF.

my motor will raise the lid until it stops but will not lower when close button is used. i have replaced the operator ( bought from e trailer), which i can use to manually open or close. i have tried changing control buttons but still does not work

@MikeL I am having the exact same problem. My 4700k fan will open. However It will not close when I press the button. I have to manually turn the knob to close it.

My vent won’t open or close. It does however, beeps when I attempt to operate it. I got up there and cleaned off the sensor to no avail.

I removed the motor housing and was able to lift the vent hood easily (manually via twist knob). The motor is totally locked-up internally; even after removing the smaller exterior reductions gears. I used this fan one time; it's a shame. The second unit still functions property. I installed two 7500K units.

Replaced motor still needs help to lift, works fine coming down?

@DennisD Have you tried checking the power source? Sometimes in this case the battery might be depleted or even a ground might be loose. The motor works fine coming down simply because of gravity and the motor not having to "push" against the load.
