Was on a call at large facility for a R.T.U. problem. Every time I went up/down ladder I took some trash down with me. Maintenance guy checked how it was going and saw all used parts by my ladder. He thought I changed all those parts, but was pissed when he learned it was just trash left behind. Did work there for 10 years exclusively because I took pride in my work, wasn't like other lazy techs.

[@jasonjohnsonHVAC]

Be very careful around sprinkler heads. I worked out of a strip plaza years back and when getting back from deliveries one day arrived to find the unit next door shovelling water out the front door. They were doing some decorating and removed a ceiling tile, and accidentally knocked the sprinkler head off the pipe. It's amazing how much water gushes out of a fire suppression system.

[@dashcamandy2242]

...and it's seldom clear water, at least for the first few minutes. lol

[@VC-Toronto]

@@dashcamandy2242 We managed to rig up a 50 foot length of 2 inch flex spa hose to direct the torrent out the door. (the store owners were trying to keep up with the deluge by using ceiling tiles to try to shovel water out the front door without addressing the source). We got in touch with the landlord to get the access code for the sprinkler control room to be able to turn the water off to the unit.

[@kailebgaylord9545]

I work for the company that makes those grease filters you see on the roof around these fans a lot (we actually at one point had some on this customers roof as you can tell by the flashing at the bottom of the fan), but I'm just wondering if there are any signs I should be looking out for when installing/doing maintenance on our filters that indicate they have issues with their exhaust fans so they can fix it before something goes catastrophically wrong. I see a ton of fans, and like you said the customer is never going to go up there so I try to keep them as informed as I can

[@fixitallpaul4847]

Get a mechanics contact style stethoscope. HF has a cheap one. Start listening to every motor you can. With time and listening you can begin to hear pending failure a good bit before it happens. The more you listen the more you will know what sounds good and what doesnt. I learned this skill as a press mechanic. Way too noisy to hear anything without the stethoscope.

[@inothome]

FYI, you won't measure any voltage drop across the contactor (or any drop) with no load on it. If you do measure a drop with no load that is a really shitty connection. But no load, no drop. Higher the load, higher the drop.

[@etherealrose2139]

The contactor is pulled in so there's no potential difference on that one leg.. If one of the contacts wasn't properly pulled in you could see a difference (up to 212V in this case) because there'd be a potential difference between the two points. I'm not sure "voltage drop" is the correct term. More of continuity since it's not under load. You should still see zero volts under load but if it was badly pitted enough you might see a small potential difference to know there's some reactance there.

[@inothome]

@@etherealrose2139 He had the motor off, so there was no load when he checked for voltage drop across the contactor. But with no load you won't measure any drop unless it was totally open and in that case you would read nothing.

[@throttlebottle5906]

good catch, always check them under load. :)

[@Sixta16]

5:30 Doing a voltage drop test without any load is pointless.

[@justme5384]

At 5:20 you can't do a voltage drop test unless you have a load on it

[@이토니]

Yep. You definitely need some kind of load. Without a load there is no voltage across ANY resistance in a circuit. Even an open contact will read zero.

[@dhelton40]

Section 110.26 has detailed specs for "control panels" including location. In no way is above a ceiling acceptable. I see this all the time, inspectors letting this stuff slide. It is both unsafe and inconvenient to work in a ceiling, on a ladder, in a cabinet with multiple motor controls. This may have been in other sections of the code in the past, but it has been there for quiet some time.

[@ntsecrets]

I’d imagine you wouldn’t see a voltage drop across the contactor without a load on it?

[@steveurbach3093]

You will see differential voltage (phase to motor) if a contact is really bad (open), creating a missing phase

[@ehsnils]

3:00 - "this is going to be a bad one" with wiring like a snake nest. Was that ever inspected? 9:58 - Whenever I do electric that shall be outdoors or in a hostile environment I'll try to go in and out from the underside of the box first and only if that's not feasible at all select other routes. That way there's a lower risk of water and dirt entering the enclosure.

[@HappilyHomicidalHooligan]

With all the unsecured armored cables and that light ballast just sitting out in the open, No I SERIOUSLY doubt it was inspected and if it was, the Inspector needs to be fired for either Gross Incompetence and/or Accepting Bribes to look the other way...

motor starter contact got overheated n melted together but one did not get stuck so it did tricked but other two did and that was why it making loud noises cause customers go up there and turned it off and other cant be turned off later they contacted you because of 2nd motor was making noise (first one was turn off then later other one failure so they called u up) good jobs chance it out

[@HappilyHomicidalHooligan]

The other reason why he doesn't change motor bearings is most motors do NOT have user replaceable parts in them so even if he wanted to, he usually can't pull the old bearings out of a motor without damaging something to the point where he couldn't put the motor back together again IF he was able to get the old bearings off and the new ones back on...

Hi, I am a very strict follower of your videos. I am a mech. eng. , and I am working in a different industry but I find your videos informative and educating therefore they are entertaining me as well and you made me interested in HVAC units even though I have nothing to do with them :) . I would like to kindly point out to 1 thing at minute 5.30 that in order to measure a voltage drop across something the device must be turned on, in this case the fan motor should be turned on, and also relay/contactor should be pulled in. This is because according to OHMs Law, V = I x R, therefore in order to measure a Voltage there should be Current and Resistance, in this case since you didnt have the fan motor turned on there was no current thus no Voltage to measure as Voltage drop. Thank you very much once again, kind regards!

[@MegaDysart]

Yeah you can't do a voltage drop test across a load without having the circuit energized, but you should be able to find open circuits using this method right? If you have a normal differential meter, seeing a voltage reading between two points would indicate that there's a potential difference, indicating an open circuit. I guess in that case the circuit still needs to be energized, however since there's an open circuit there'd be no current flow. And you'd need to be sure you're testing 2 legs on the same circuit. Maybe I'm misunderstanding
