That jump when the motor kicked in.. 😂😂😂😂
I wasn't expecting that! Haha it was so loud too😂 Thanks for watching! 🙏🔧⚡️🤙
We all did! MY dogs started barking.
Jump scare

@@jimbeam275 💯😂
When a 3-Phase-Motor is humming, it usually means, that it is missing a phase. With the contactor rattling it probably burnt up the points and was making a bad connection on one of the phases. Best to allways confirm 3-Phase Power at the Motor itself, before calling it a dead motor :)
That vibration is a nightmare though. Best to replace that whole heep of junk.
MY thoughts exactly 🥸
I anticipate your videos everytime,you definitely helping me in the field, thanks for sharing so much knowledge
Your boy got rattled with the belt screaming 😂
happen's to me every time XD
That thing had me shook! 😂😂😂
@@teldarion5277 I wasn't expecting that 😂😂😂
Thanks for watching everyone! 🔧⚡️
The "shaking" of the contactor is called CHATTERING.
low voltage is part of problem. The contacts on the contactor are probably bed. The belts are loose. The squirrel cage may be unbalanced.
The buzzing is due to what's called magnetostriction. It's the plates in the coil that are vibrating. Transformers can make the same type noise.
I should make my staff watch all his videos!!
Definitely! Send them a link & I think it would benefit them a lot. I wish I had this channel when I was working up the ranks. Thanks for watching! 🙏🔧⚡️
Motor was single phasing at first.
It’s a bad motor starter, and something going on with the belt
That is true. Definitely a bad motor starter. That will be replaced along with the belt and see what else can be done until the unit is replaced 👍 Thanks for watching! 🙏🔧⚡️
Good job Jumper......
You troubleshoot better than most electricians.
You sound like your from NY
Great video. Thank you for sharing
Nice work Jumper Man.
Thank you!! 🙏🔧⚡️🤙
Thank a lot sir.. I'm from Philippines
Probably have a 3-phase motor single-phasing the contacts on the starter probably wasn't making. But where weird is the heaters didn't burn up hmm good video
Dungeon time!
Haha facts! Such a neglected unit as well! It did it's thing since 2012 apparently. Time to go soon! Thanks for watching 😂🤙🔧⚡️
Good work.
Thank you!! 🙏🤙🔧⚡️
Maaaan them Mexican Homies be Playing dem Rolas 😂😂😂
You fix the belt?
Nope. It was just replaced before I got there by the building. Next visit, I will be replacing the motor starter, changing the belt and doing some maintenance to see if anything can be done to make it better until the unit can be repalced. Thanks for watching! 🙏🔧⚡️🤙
@@JumpermanTech I'd check the alignment of the pulleys and sheave depth.
@@mikekolczynski5665 Facts. Thanks for the advice & thanks for watching! 🔧⚡️
spooky! great video 🫣
Maybe it was a tight belt?
Yes, definitely. A little temporary belt dressing could have possibly done wonders for that thing, lol. I feel sorry for them neighbors!!
3:33 is that an magnetic starter
Yes, it is. It's a motor starter. Basically a contactor with an overload device. Thanks for watching! 🔧⚡️
Motor starters are used to protect the motor, whereas circuit breakers are used to protect the wiring. A motor starter has an amperage range it is rated for with a fine tuning adjustment to make it trip at maximum motor draw plus a percentage for loss over the wiring
😻💚💜💚
💜🔧⚡️
Just replace the lot hahaha
Just get a new building 😂🤙🔧⚡️
@@JumpermanTech amen.
