I just came from residential/light commercial and I’m now exclusively working in commercial/industrial hvac. And it’s all 3 phase so this was a great tip brother. I’m always receptive to new tips and tricks. Even the fellers in the comments bring good stuff to the table thanks guys 👍🏼
Thats what mine looks like. I replaced it i had a spare new one at home. My unit still has issues though after replacement the fan wont turn on or the compressor. The cap is testing 3.5 MF lower than its rated so ill replace that too and see if they kick on.
Love them quick tips , mate , I'm glad you're bringing them back ! 👍 Reminds me of a company I've worked at before , they replaced a big @$$ exhaust fan but didn't bother changing the contactor , turns out it was faulty , the motor worked for about two hours and tripped the disconnect . When I came and saw it was tripping , I checked the windings and they were shorted out ... Expensive mistake they made , ey !
Hey Chris. How’s it going in Beantown? Looks like it’s a might bit chilly there. I don’t know if I told you but I retired at the end of December. Mama and I are in Utah visiting some friends and enjoying the time away from HVAC. Great video. I never thought about checking continuity across the contacts. I too also checked voltage drop across the contacts and voltage across the legs on the load side of the contactor. Have a great Wednesday my brother and stay safe. God bless.
Blaze Eisner hey Blaze. Thanks for the comment bro. Yes there are multiple ways to check these with voltage drop as well. I figured I’d keep it simple and show it this way because I couldn’t show this live in the field because I had the customers maintenance guy with me the whole time on the roof haha . Congrats on retiring bro ! You deserve it. I wish I could hahahah.
Mr Psychometrics yes , I would’ve loved to have shown this in the field but I couldn’t because I was on the roof doing this call with the customers maintenance guy so I couldn’t take a vid
Adan Diaz yes exactly but I couldn’t show it in the field. I had the maintenance guy from the customers place on the roof with me . So can’t being taking vids when with a customer
those larger contactors should be replaced once a year because they get pitted after 9 or 10 months...just what i have been seeing over the last 20 years

Another great tip. I always did a voltage drop (especially on 3 phase). Many times even though they didn’t look bad, they’d drop a few volts
I would have definitely changed that contactor based on how it looked. Great tip!
Another great video 👍👍👍
Harry Dickson Thanks Harry 👍
Very helpful for a newbie! Thank you.

You’re the man boss👍😎

Great..thanks
1:59 - Isn’t that the type of contactor that has replaceable points? Cheaper than a whole contactor. Thoughts?
you could also check the volatge a cross L1 to T1 and so on to see if its bad or not.
Mr Psychometrics yes , I would’ve loved to have shown this in the field but I couldn’t because I was on the roof doing this call with the customers maintenance guy so I couldn’t take a vid
Great video. Is that commercial contactor HVAC ?
ZE KENZY yes , it was in a refrigeration unit but these will be in hvac units as well
So what causes pitted contacts? Is it overcurrent?
I'm wondering the same thing. Mine looks like that
Should’ve showed how to check it with voltage, across each leg should be 0v when working & 208-230v when open depending on voltage
