What's the install warranty like on this puppy ?

That's part of the garage door experience, is getting
the twit back who installed it, to fix it right.

The thing has sensors. Like sensing when the motor is
drawing too much current, then reversing the direction
of motion to relieve the pressure. That's so if someone
gets stuck or pinned by the device, it automatically
does the right thing.

The Crocodile doors are just a standard roller door, sold by many other

door they supply is exactly the same has my door, which I sourced
direct from the factory and fitted myself - bet I paid one third the

Have you checked the tracks are clean ? A spray with some lubricant may not
be a bad idea. I assume it wasnt used much during the lockdown, it may
well have gummed up. A bit of lube and a few manual open / close cycles may
help.

Mine doesn't have one, so I don't know what it is. My door has a sort
of series of nylon chain links, drive the chain over centre and it
forms the locking mechanism - try to lift the door and you would be
pushing against the over centre 'chain'.

The drive motor is a 24v ac tubular motor and gearbox, that includes
meachanical limit switches, for for going up, one for going doing and
they are very precise.

The control system includes a maximum run timer and a maximum current
sensor - this last is what your problem is, it is set too low.

Jim - It is pretty much the same as my door, except my door is inside
yours on the outside. Even the manual winder is on the same end of the
mechanism - the left looking at the roll and the motor is on the left.

My best guess is that it was sticking in the tracks, drawing too much
current, so the controller shut it down to prevent damage. The current
limit might be adjustable, maybe set too low - ask your guy when he
turns up.

But this could lead to the motor burning out. Check everthing mechanical
first. Not familiar with roller shutter - but presumably they have some
sort of spring counterbalance - is this set properly would be my second
question after checking the runners.

There are no rollers in the tracks either. The ends of the alloy slats,
have a nylon block fixed to every second slat, which keeps the slats
centralised in the guide channel.

You would have to compare the noise level, to what
it sounded like when it was new. I thought I could
hear something there that sounds loose, around the
part that does the winding. But maybe it was always
like that.

As for the choice of track lubricant, I'd see if I
could find the manufacturer manuals and docs, for
suggestions.

The track itself probably needs to be "cleaned"
rather than "lubricated". There could be sand in the
track for example.

The little wheels it glides on, could be grease-packed.
Spraying WD40 on those little wheels, the WD40 is a
"lube robber" and it can help remove manufacturer
grease from where it's needed. That's why I don't
spray WD40 around like a room freshener here. It
can do more damage than good, depending on what
you point it at.

I hadne;t appreciated it was a shutter door.

Our roller garage door misbehaved recently closing fully and then partially opening up by a few inches. Turned out it was a feature of the sensor that detects when it is fully closed. The sensor is a small battery operated circuit that is linked to a pressure sensor in the rubber seal on the bottom edge of the door and communicates with the main control unit by radio. When the batteries start to fail the behaviour mentioned in the opening sentence happens, changed the batteries and all is normal again.

Mind you getting the batteries was one issue and their price eye watering.

funny thing is when it is going up last night I hung on the door and
stop it moving but when I let go it started again..shirley the sensors
would have dealt with that if they were working ?..just going out to
