Electrically Operated Roller Shutter Door Fault.

Zoomup

The customer reports that the roller shutter door closes on button but fails to open properly. He had to use the manual handle to open the door. The door seems NOT to be mechanically seized.

The control model is a Teleco TVPRP868N09. It has been working for me on a sporadic basis. It always seems to close the door but stutters or cuts out on opening. The operation is not reliable. I suspected the limit switches but they seem to be working o.k. if they decide to.

I then suspected the motor overheat cut-out embedded in the motor. The motor is inaccessible as it is contained in the roller shutters' shaft. I suspect that I ran the motor too long and it has a short duty cycle when testing it, and it overheated.

Has anyone any experience of this fault and how to rectify it please?

    Update. After I sprayed some lubrication onto the end bearing and motor end of the shaft the door seems now to be working o.k. The owner said that it worked for him recently too. Again today it worked full travel up and down perfectly. It gets little use, perhaps once a week so it may have been suffering from sticktion.
