AC Not Cooling Condenser Not Starting Fan Really Hot

[@watermanone7567]

Got to love the late night calls. Supposed to be 95F here in the next two days. Will be lots of O.T. trying to get stuff running. Usually the ones that quit are the ones that have had no maintenance for a few years. Thanks for that video.

[@smartpig129]

I carry around a roll of iron strap for when my new caps don't fit the brackets of the old caps. Makes life a lot easier sometimes.

[@thehvachacker]

Smart Pig me too and usually the turbo is bigger in diameter

[@FrozenHaxor]

Those capacitors are dropping like flies, I have replaced one in a bloody paper shredder yesterday. It was completely tits up. Wonder why they didn't come up with a better design - or it would be too expensive

[@thehvachacker]

FrozenHaxor their garbage only caps that seem to last are the turbo caps I install. All the rest puff up and knock the system offline

[@TheGhettoLobster]

Idk how anyone can hate on the turbo caps. My only gripe is they are too big to fit in a lot of the spots that old capictaors went on units with a lack of space

[@thehvachacker]

Yes I use band iron and make a bracket for them if they won’t fit. Easier to keep stocked

[@Bluefox43143]

I carry the right size caps for what ever I need. And they will explode. They used to have that bad oil. Be careful

[@emprsnm9903]

That thing must be a Carrier. The engineering is reminding me of my tech2000, the resonating sound too. It's like they didn't change much of anything going from r22 to 410a (chassis wise).

[@soloch69]

Great video like always bro 🙌🏻🙌🏻🛠⚙️🛠

[@Jon-hx7pe]

Why will this unit being replaced rather than have the leak repaired? A shame - nice quality with good service access, uses 410a so the phase out isn't an issue. Probably better than the stuff produced now without easy access to the compressor.

[@johnmurphy6366]

Jon [Insert Last Name Here] he said the house system is being replaced to accommodate zoned cooling,plus the unit is from 2002;its past its serviceable lifespan.

[@Jon-hx7pe]

A 2002 condenser unit and evap coil are still serviceable in most cases because the parts are generic and cheap. It's just a question of how much money it makes sense to put into it to fix a leak. For a nice unit like that already 410a probably 12-13 seer, may be worth it. a cheapo leaking builder's r22 10 seer wouldn't be fixing at this age. Claiming not serviceable is just an excuse to sell something new in most cases. 10 to 15 year lifespan is bs, there are 20 to 30+ year old units out there running just fine. yah i heard the zoning part after writing the comment. hopefully the new one will be a 2-stage with the panel keeping second stage off until enough zones are calling.

[@thehvachacker]

It has a evap coil leak and they don’t want to replace the coil. They want the 25 SEER XC25 modulating condenser and an i-harmony zoning system. The condenser here is worth keeping but the air handler is sagging toward the return. I was able to support it and stop more sagging but the installing company abused that air handler

[@Bluefox43143]

Keep in mind that 410a will soon be gone also. Now I read that 22 is not as bad as they thought.

[@Eddy63]

Sure was cloudy that day wasn't it Hackster ... Lol ... Good vid ...

[@jrchicago9216]

I change run caps at 10 years because it’s a component that can degrade over time at high voltage, it a cheap $15 component and it avoid potentially severely damaging to the fan and compressor as rotor lock fries the crap out of them. Our little 9volt MFD test meter does not detect high voltage pock mark failures (called leakage at high voltage). Think about it, 50% of no a/c calls have failed caps. That means we should have changed the run cap long before. When they do fail bad, these bulging cap’s got that way at high voltage...right? If I were in a hot market (Sun belt) I would probably change these at 5 or so. Think of it as “failure prevention” since these units run far more. The biggest mistake I see is techs adding a booster start on top of an old run cap. Oops, The problem is, if that run cap has pock mark high voltage leakage shorting, that was the real problem to begin with. You don’t want an old degraded cap fighting with the new cap. Here is a secret. Change the run cap and listen to the compressor. Add booster cap only if it feels right to do so. Why do I say listen, because when I change out run caps preventatively, about a third of the compressors sound far more robust. So what might that mean... We could easily wager that a third of those run caps were degraded. Guess what, I pulled MFD readings on almost all run caps I replaced and way over 90% were within spec on my MFD meter. So our meter is a little skinny fat liar. Something like that... I also date my caps with a magic marker “7/2019 Prev-Mait” . I tag or write dates and notes on almost everything I replace. ULINE has blank white write on “service tags” with a thin marker pvc tags for leaving notes on components for any future techs and myself. I do change the metal lanyard on these tags to string in electrical component areas so it won’t short out anything flapping in the wind or gusts. I realize techs are trained to just test caps. But given the facts, it’s not enough. Age is the other factor. I studied caps, that caused me to pay more attention over the years to audible sounds and prevention.

[@ME-kv8ew]

If it works, use it! I would have no complaints.

[@lanceb940]

Nice work 👍🏻

[@rivec33]

So a bad capacitor can cause the fan to get hot and not spin? It’s 1 am and woke up hot and sweaty to find my ac not working, fan isn’t spinning and it’s really hot to the touch. Was going to try to figure it out in the morning. My initial thought was motor bad since it was hot but I’m not an expert.

[@truckinforever985]

Might have missed it, but what was the motivation to go with the Joblink system over a tradtional digital manifold set? Inquiry minds what to know.... thanks, keep up the good work.

[@thehvachacker]

I wanted smart probes for awhile, was considering the testo yet most on my Facebook page talked up the joblinks. I’m a word of mouth kind of business so when buying new tools I figure I should go with same approach. Yet I was doing a start up on a couple 30 ton RTU’s and my Testo 550 after 7or 8 years suffered a static shock and won’t read subcooling anymore. The next day I was running calls for the emergency service so I decided to go to johnstone and buy them. Since using them I can never go back to a manifold except to recover or pressure test. It’s so much easier to switch refrigerant circuits on maintenances, no hose = no lose of refrigerant.

[@jdamx_0000]

did you find the leak on this unit? kinda sucks to add more refrigerant every two years, low load means more problem in the future and costs a lot for the client in the long run, but i get it, its a 2002 unit so eventually you'll have to change it anyway. nice video even tho it sucks to have night calls

[@thehvachacker]

This system was scheduled to be replaced in a few weeks. I think I left that in the video the customer saying when my company was replacing the system. This was around july 4th last summer with most days averaging close to 100 degrees. I was getting home overnight that week around 1-2 am being the unlucky one being on call.

[@dalejustice9207]

My hvac has been crazy all summer. First the capacitor went out, then it wouldn't get cold after that, called a hvac tech n I had the r22 in it. So he just puts a pound or 2 of 407b only mixes it and says it wont harm it. Charged me 105 bucks, never did get cold or cool. A guy came out completely drained it vacuumed all the stuff out until it was completely dry. Filled it with 407b n added the poe oil filled up, still wouldn't get cool or cold but wasn't freezing up like before, just wasn't cool, just like warm. He noticed that some one had wired the emergency heat to come on when the air conditioner was on, so he just unplugged the emergency heat from it. A week ltr it started freezing just like it did bf when it wouldn't get cool or cold and almost all my Freon he put in it was just about gone, so he filled it back up n said I will be back tomorrow to find n fix the leak, well he never came back n it never froze again or anything n was good about 2 weeks. All of a sudden it was on running n I hear it stopped n I checked n the condenser fan stopped running. I could hear the condenser running so I pulled the outside fuse n I wanted about 10-20 mins plugged it back up n it started working like normal. Long story short this whole week it may run 15 min to 5 hrs n the condenser fan will quit again n will not turn back on spinning till I take the top off n spin the blades n barley peck on the motor n when I put the fuse in, it kicks right on n may run 15 mins to 2 days before it does this again. I know the unit is about 20 yrs old n needs replaced, but I don't have the money to replace it. Do you think it is the motor going out of it for the fan? The capacitor seems to be fine. Do these fan motors have brushes in them? I have searched every where on google n for sure have not found any thing on these. I thought about just taking it off n taking it apart to see, but before I do I wanted to see if some one knew if they could be re built or not. Thanks

[@thehvachacker]

Usually the motors just get tossed. yet instead of brushes you have a rotor and a stator. with 2 parts of the coil energized from the 120 and a capacitor changing the phase or creating the phase to create the magnetic force to make the rotor spin

[@joeydelmarsjr.646]

so what are those jumper wires on the cap for? what do they do or purpose?

[@sparkytech8787]

the jumpers supply each individual caps all in one cap

[@johnmurphy6366]

By changing configuration of jumpers,changes MF value,allows him to replace multiple caps,without stocking many sizes.

[@brendanf8969]

Curious, how do you like the 324? I need a clamp meter and have been looking at the 324, does it do everything you need in the field? Does it read microfarads? Thanks for the great videos! Keep up the great work!

[@thehvachacker]

It is not a good meter for heating. I got it at a garage sale for a few bucks. For ac it works but doesn’t do flame current micro amps so for HVAC it’s not the best. Go with the 902 that’s my main meter and does everything for HVAC. My 902 display light stopped working so I been using this one at times

[@brendanf8969]

@@thehvachacker thanks for the input! Much appreciated!

[@joedillon159]

Anyone ever had a puffed up capacitor to explode? Wondering if dangerous in this condition shown.

[@thehvachacker]

They can explode and fire out the oil inside. HVAC is one of the most dangerous trades and always have to be ready for anything

[@joedillon159]

Thank you for your reply and your videos.

[@throttlebottle5906]

nearly all of them are "protected" meaning fusible links inside, upon bad short or issue they'll fail open circuit and generally should never explode. now if gets heated quickly by fire or torch it could blow the top, but they also have either stress relief lines to burst apart at or a rubber/solder covered hole to vent out of. BUT anything is possible, if it's smoking hot with boiling, ticking and snapping sounds, stay away :)

[@joedillon159]

Thank you very much for the explanation. That makes sense.

[@zhengqiang5006]

What kind the capacitor do you use ? May I know which brand is it ?

[@zhengqiang5006]

Is it call TURBO...?

[@myoung99wood]

It's a multi tap called a turbo 200. It costs 5 to 10 times the amount of a single value capacitor but it will work in place of almost anything. It's great for emergencies but I'd never use it on a regular basis just to save space in my van.

[@thehvachacker]

It's called a turbo cause it is a life saver to those whose ac has a defective capacitor. You can make this replace most capacitors. For a service truck this is all that needed. These are built better and stronger than a standard dual cap and also come with a 5 year warranty

[@hvac1015]

Im surprised the customer isnt outside next to him hounding the shit out of him

[@thehvachacker]

Why most customers leave me so I can work. this customer never asked how much the cap or gas would be and just handed me credit card and 100 tip . It's rare a customer is around while I'm working, usually they just check up to see if i need water or if I think i can get the system working
