I have a household unit in the laundry and a commercial unit in the garage..fire extinguishers are pretty bloody cheap.
Was the opener capable to the load?

Hey! I'm from Canada and the metric system is superior! lol
Careful some ambulance chaser doesn't sue you for no "don't try this at home" warning for his client. 😀
Really a great show, please keep them coming. Kudos Cheers
If it was getting hard to pull the chain to lift the dock leveler, what would be the possible reason for this?
We should start a gofundme for fluffys family

POV his mind thinking he fixed it” I did it I fix it I’m a genius” garage door opener” you are a dummy”(garage door opener, explodes)
Thank you so much. This information is literally impossible to find on google. You'll find nothing but junk SEO spam articles from garage door repair companies.
Thanks, it worked like a charm ✨️
OMG you are a wizard at teaching!!
Nice
Fantastic job explaining how this system works. Thank you

Thank you, Sir!
Great video!
Got same length torsion spring and followed the steps for replacement of springs; but issue I see is garage door only lift up till 1 foot , stay stuck and does not move up regardless how much manual lift force I put in (in manual mode). please guide. I tried going up to 33 quarter turns (16.5 half turns) as 31 or 30 turns was not helping, rotation was clock wise for 33 quarter turns.. my old part was 218 wire x 29 long spring and new one is 225 wire and 29 long spring.
You might have the springs flipped the wrong way
Amazing, the fundamental of counter balance!
That’s a loud pop
Good video, Thanks
The capacitor failed in the opener and caused it to explode
not sure why he does this test, always broke in the middle, per physics
A couple questions: If you have multiple springs on a torsion system, do they all get the same amount of winding as say a single spring? For instance if a single spring needs seven and a half turns, would a double spring system also require seven and a half turns on each spring? I have an industrial door on my house, and that thing must weigh about 500 lb. It is kind of heavy to get lifted, it is balanced in the center, and then it wants to slingshot open once you get up over on the horizontal part of the track. Then it is difficult to start to close, is balanced in the center again, and then wants to drop to the floor after you lower it past the center.
it's so detailed and straightforward!
