This is a downdraft vent behind a range. My vent seemed to stop working in any way (up/down, fan on/off, lights to switches).

After some work and some lubricant, I had it working with assistance but it wouldn't push the vent up and the fan would go on and speeds could be changed. Now I can hear a switch start but then nothing. No movement, no fan, no lights.

I can get current through the L3 N3 terminals on the main PCB and as I said, have been able to generate some control of the switches. The switches worked at this time and there is no foreign debris between the silicon buttons and the board.

Having removed the fan assembly, I tried replacing it in two different positions, currently in the down position with the lifting arm pointed straight down so the hinged joint is below the motor’s box.

At this point I suspect the motor does not have the strength to lift the unit but as I no longer get any useful response I am not sure. I also haven’t been able to get the motor to turn on its own without being hooked to the unit but I don’t know what sensors/switches need to be in place to allow that either.

The vent moves up and down easily by hand when disconnected, very little resistance other than weight alone.

Anyone help?

Please note that I am a homeowner with some limited experience in appliance repair.

Thank you for your assistance.
