Hello,
First thank you for viewing and replying. Of course we have licensed technicians work on this elevator only. However, what we find is that they they get the elevator up and running by changing the fuses and coils, refining the relay and replacing the carbon pads, adjust the cam arm etc... This gets the elevator running for a short time and then it goes down again. Sometimes it can run up to a month or so and sometimes only for a couple days. We enter the doghouse after it goes down and more often than not a coil or a fuse is out and there are nuts and bolts on the ground and wires have gotten loose on the front of the mother board. Again, this elevator sounds like it is working very hard or grinding compared to the other elevator that is the exact same on the other side of the building. When you press the call buttons or floor buttons the elevator that breaks down almost jumps into gear and then grinds its way up. It seems like the contacts are not connecting correctly and the power is in and out. We have exhausted many licensed technicians that seem to not understand the root of the problem and have entered the forum to seek advice that we can then pass on tho the technicians.
Thank you so much
