Garage door operator fault finding – Sherlock Holmes style.

Taking Photographs

I take pictures before I start. – this way I can study them later and I’ve been taking photos about things ever since I knew how to load a 35mm film camera – along the years I developed a skill other than fixing stuff and taking perfect photos, I can tell by just looking at it what the problem is.

Realizing we all see different things.

My job is to fix this garage door operator. So I won’t be paying attention to the spiders, grease, dust and stuff I can trip over. 

Images below will be better if you read 1st and then click to enlarge.

#1

Assess & Repair or Quote to repair.
Make: Digidoor
Model: II (220vac) Powerhead designed to be installed horizontally in an overhead hanging way.
Extrusion: 2.2m Designed for tip up doors combined with said powerhead.

Quick analysis. This setup is born to fail and be unreliable. I cant fix a modified installation – I can salvage it to run again, no problem, and this is why I wont be able to warrant this repair.

Closer look into why it failed. – Remember design? Horizontal and this vertically installed. Hanging stuff only goes one place on its own, and that is down!
By installing this extrusion in a vertical manor, meant the closed run time limit sensor will be exposed to gravity, cleaners, kids, balls, cars, floods and spiders.

Do you think that wire is important? It is, but why is it just hanging around and broken, how does it just break?

I get these questions from clients yes.

Answer: (refer to #2)

By installing this extrusion in a vertical manor, meant the closed run time limit sensor will be exposed to gravity, cleaners, kids, balls, cars, floods and spiders.

And this is what happened.

  1. Open position run time limit sensor cable damaged – can only geus how
  2. Pushing past this sensor the motor jammed on obstruction
  3. Obstruction sensors failed to stop the motor when hitting obstruction.
  4. Causing the whole obstruction sensitivity mechanism to collapse and break.

#5

All the damage here was cause by wrongful installation, the white ring mark is where the drive pully is catching the powerhead. and the yellow block holding the power head to the extrusion is broken.
