What Causes MaxxAir Maxx Fan Lid Not to Open or Close
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.

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.

T motor raises the lid and will not lower it, must be cranked down, the operator was changed already. i have swapped out a control panel from the other fan and does not work. i bought anew pcb, still does not close, i can reverse the wires to the opener and the lid will close but not open

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.

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

The door on my maxxfan Deluxe 7500k will close but will not open on its own. If I open manually the fan works. The unit is brand new.
