Found crack in cylindrical part inside A/C condenser unit

Accumulator. Possibly, do you have a crystal ball? Do you have a picture of the "brown stuff"?

Pressures??? How about superheat and subcooling???

Can't see or test it through my computer screen... and my crystal ball is in for repair.

We would not be having this conversation if I had not noticed what is shown in the photos. Do the photos reveal that something is seriously wrong with the part or is it just a crack in the paint as someone else had suggested?

Thanks,

J.

Yes.

Jay,

I am guessing that the light-colored cylindrical part you have photographed is a large electrolytic capacitor, typically used to start the outdoor condensing unit. It is very difficult to tell from the photo you provided. It could be a receiver/drier, a low ambient kit, or other refrigerant part, but I doubt it.

It is very unlikely that you are leaking freon based on your comment that cooling is adequate. My advice would also be to not worry about this item. If and when it does fail, you will need to deal with it then, most likely with a complaint that your outdoor condensing unit does not appear to be operating.

Maybe some of the "experts" on this newsgroup can offer better advice. Based on my participation on Usenet and Arpanet dating back to the 1980's, I must say that I have never seen a more pathetic collection of people than I have encountered here. Many questions are answered with snide, sarcastic remarks by people have sniffed far too many chlorinated and fluorinated hydrocarbons. Some questions are ignored altogether. You might consider posing your question at alt.home.repair or one of the HVAC forums on the Internet. This newsgroup is about as dysfunctional as any I have every seen.

More than likely just a crack in the paint... unless the "brown stuff" looks oily.

JayN;

The part is a suction line accumulator which was / is prevalent in Carrier's product line during the 1980's 38TH------301 comes to mind. Aluminum coil, MD Carlyle compressor....

The accumulator has sweated so much [from being overcharge with refrigerant] that the paint, has let go and rust is setting in. [Steel vessel]. Soon, it will start leaking refrigerant.

Your best bet? Call your local HVAC contractor [licensed and insured] and get a bid for replacement of the complete system. Upgrading will cut your electrical use [when the air conditioning is on] comparatively in half. The EER of those earlier units was in the 9.5's - the newer stuff to day is much more efficient.

I don't think it's a crack in the paint. To me, it looks like enamel, or possibly plastic. More likely plastic. Call your AC guy if you want, but I am not going to worry any about it.

Large electrolytic? Hmm. You have a good imagination. Would that be about

I'd say receiver. Since we're all snide, I need to write "you blind hack!" We're not disfunctional, we're cantankerous.

Cumulator? Neat! I guess that would make sense. After all, receiver needs a high torque comp. And the comp we see has a round shape to it, suggesting it's a piston model.

Did the peak through the top of the condensor look like this?

Especially, since you *think* it's an electrolytic capacitor. LMAO

Don't you *think* that'd be in the electrical compartment?

Good!!! Bye-Bye!!!

An electrolytic capacitor the size of a quart (maybe gallon) paint can?

You're thinking of a Leyden Jar, last used by Ben Franklin in his famous kite experiment.

I will not venture an opinion on what the item is in the original post, but I WILL agree that this newsgroup is unlike any other I have read. The general view by most, is that a question is posted so that the poster can avoid hiring a HVAC pro. Having read many replies to questions posted, I can understand why someone would want to avoid such an action. They probably fear that one they would hire might turn out to be one of the sarcastic "Pros." Not only have many of the replies been not helpful, many have suggested actions that would make the situation worse. It is one thing to refuse to give an opinion or help, but quite another to suggest an action that would damage the unit or cost needless money.

The poster in this thread never suggested for a minute that he was about to fix the unit himself, he simply was trying to ascertain if he had a serious problem and if it needed immediate attention. Most often the recommendation is that a poster hire a pro when he posts a question. That is probably good advice in MOST situations. But even when a poster reports on a job that a pro had done and whose results were poor, the poster is criticized for having chosen the wrong pro. In other words: Don't do anything yourself, hire a pro. But if the pro did lousy work, it is YOUR fault for having chosen the wrong pro. I cannot understand how a person who learned a trade, and presumably is proud of his trade, can ignore bad work by others in that trade.

In recognition to the few in this newsgroup who have replied with civil replies, your comments are duly recognized. To those who post to mislead or cause harm, you should be ashamed of yourself.

Now have at it and post your vulgarities and wise remarks, as it appears that many of you have few customers to service. I wonder why???

Oh boy, another asshole who *thinks* everybody deserves FREE advice on everything and *if* they don't get that, we should be condemed. Hey Putz, I have a question, are you Stormy's long lost brother?

Yes, there is something peculiar about some (thankfully not all) of the regulars of alt.hvac that is not seen in other technically oriented groups or web-based forums. In others if you ask for advice about something that hints that you are in over your head or creating a danger for yourself or others they'll certainly tell you so, but nowhere else is there such a level of condesention and resentment for anyone not part of the high priesthood asking pretty much anything, even merely, as in this case, whether or not professional attention is required. It's like they resent that customers even exist.

If replacing the part would not be cost effective for such an old system, then I am wondering if there is any chance the life of the existing part could be extended by wrapping the part with some kind of tape and/or insulating material to prevent moisture from consensing directly on the rusty metal casing of that part when the unit is running?

Thanks,

J.

Schlock on some Rust Oleum. The real stuff, in the pry open top can. Not the thin runny spray paint stuff.

Would that really stick to the rusty metal? Doesn't the rust have to be brushed off first in order for the paint to really stick? I would be scared of using a wire brush to try and prepare the surface of a tank that is pressurized. Likely the most I could do before painting it would be to wipe it off with a cloth.
