Fan-tastic ceiling fan (1 Viewer)

[Figaro]

My ceiling fan has stopped working
Had a fiddle with it, the motor (to open the hatch) starts to operate but immediately stops before opening. It's a 12volt motor but it's only getting 9.5volt according to my multimeter.
If i connect the motor to 12 volt (separate battery bench test) it continues running.
Does that sound like a PCB problem, anyone have any experience of these fans or where they can be repaired ?
TIA

Sounds like a problem I had with the door window motor, quick try and stop. The electronics detected too much current, much lubrication and helping glass and it has been fine ever since.

Since you can power it off 12V, do so a few times with a lot of lubrication and keep your fingers crossed.

Naturally, any bad sounds or smoke - stop.

Have you turned the thermostat up?

Yes, turning stat down causes it to activate motor to open hatch then fan motor kicks in when open

Low voltage when motor not running may be a bad connection. Check for corrosion?

Although I have one, never had one to bits, I don't think there is much in the way of electronics unless you have the rain sensing one. At a guess I would think it could be thermocouple playing up.

It does have a rain sensor and there is a pcb doing something.
The dome lift motor runs continuously when bench tested either on 12 volt or on a 9v battery
But connected to the unit, it cuts out after a moment and this seems to cut the current to the motor which although I`m not very knowledgeable about these things it leaves me thinking there may be a pcb problem ? so I`m out of my depth !
I`ll try and find someone that repairs / services them but no doubt they`ll want to sell me a new one

If you are saying in both cases the motor is loose from the unit then there is the possibility the pcb senses motor rotation via a sensor in the unit and when it senses no motion it assumes the unit is jammed or at it's limit and stops.

Have you run the motor off a battery connected when to the unit to see it it turns then and might clean up the gearing ?

I might try that, but I can open the dome manually which I have dome to make sure it`s not the seal that has stuck to the dome
