Here is a part # I need to know the fan motor size, amps, rpms,everything, please? The store did see the old motor, but went by what I had written off the side of the unit. Sold me the wrong one and it burned out. They had asked for all that info but the number on the part was all I had. Turned out not the original and did not match the info on the unit. Where to find in So. Md and what is all the info on it, please? Size, rpms, voltage, etc...
Thanks.

Most all motors have the size,RPM`s ,HP, direction that it turns,and wiring diagram on the side of the case/housing, and also the size capicitor that it needs,you have to buy a new capicitor for each new motor you buy, don`t try to get by with an old/possibly unmatching capicitor,
Most anywhere you go they would rather see the old motor so they can give you the correct motor and capicitor

The old motor had only the serial number. The paper that was there was so old not a spec of ink was on it.

BUT... he had wired it right according to the HVAC tech that came today. The breaker tripped several hours after wiring and I came here thinking that the motor was wrong size, to ask you guys for help with that, before buying a second motor.

What happened was, he used black duct tape instead of Caps to hold the wires together. When the Tech opened the unit to see why the unit would not come back on, the "Main wire" was lying on the frame. Apparently the tape got hot and came unglued. Then the wire hit the frame, and apparently it shorted out my Compressor. I was not trying to save money by not letting HVAC techs replace the motor. They had given me a tough decision to make. They came out Friday and got the fan working. It stopped again and the Service Manager called me back and said that I needed a new fan motor. The reason I did not let them do the job is the decision they gave me: They said that my unit was so old that they may actually break the unit beyond repair JUST to get the old motor off, make a decision and get back to them. Theyfelt I should bu a new unit but for me that was not an option.

Meanwhile my cousin said there was "Liquid stuff" that he could use to safely remove the old motor, or he would cut the bolts out. But it turned out the bolts turned fairly easy and he replaced the motor.

BUT.. he secured the wiring with black duct tape instead of caps. Why, I do not know. He stayed for hours to make sure that it was wired properly and would run. It ran seven hous until I turned it down at night. Sunday morning it tripped the breaker.

Bottom line when Techs came out today, the Duct taoe had melted, the main wire came off, hit the frame and shorted out my Compressor. The unit is now dead.

I did not tell my cousin. He is not an HVAC Tech and worked all day to help me. It would make him sick to know that that tape did not work and resulted in a blown Compressor. I am not angry but I wish that the Company had not scared me into thinking that if I hired them to replace he motor, they may have actually broken it instead. Had real HVAC techs done the job it would right now be all right. They tested the Compressor last week and told me the "Amps" were very good. That Compressor was old but still good. I could not afford a new unit and my HOA does not allow window units. I was stuck. And now I am REALLY stuck. Out of 135.00 for the new motor.. out of 150.00 labor for the HVAC Company. And no air.

I have an 85 year old mother who is bedridden. The fan is making her throat sore. If not for that, I was raised with no AC in the South and coud make do just fine until I can afford a new outdoor unit. I was too depressed to think today, but I will try and come up with something tomorrow.

I have many Electricain friends but none returned my calls until Sunday.. AFTER the damage was done.

If it were not for my mom, I would laugh at "Duct Tape Ruining My Life." And had I been actually WATCHING.. I would have known to tell him to wait and let me go to Lowe's and buy Caps. I would have KNOWN that he needed Caps. I was so happy that he had the unit running that I never asked what the tape was for.

If you are a Praying man, pray for my moma and me, please. And TY for responding. This is a neat site!
Because of how it all nded, there was noting I could have done differently, but watch and I would have KNOWN, to use Caps. Next time I getwork like that done , I WILL WATCH. The little knowledge I have would have helped.

Sad story.

But, duck tape is conductive. It conducts electricity.

Not quite sure if I can offer any suggestions. There will be a separate breaker for the outside unit. Usually a board fuse and a breaker for the air handler.

I also can't tell what fan got replaced. Indoor or outdoor?

Also not real sure what could have caused the compressor to short out. A short across the capacitor could do it.

I also don't know what if anything is running now. Inside blower on fan only; Outside fan on AC? Do breakers blow?

I'd be concerned about the contactors and the outside wall disconnect.

Might not be hopeless. But will be a challenge. No one like to clean up someone else's mess. They usually pay dearly for it.

Oh thank you... I can tell you that they put a "Tester" on the wire to the Compressor and it "Beeped." They said that that was the worst sound I wanted to hear because it meant that the Compressor was dead.

I am talking about the Fan Motor being replaced. The cousin who installed the new fan motor used Duct tape and the Techs later said they found the main wire with tape on it had come off, touched the unit itself, and they suspect that it shorted out the Compressor.

But I just talked to the Service Manager again because... they had also said that they were disconnecting the Compressor to see if the Fan and something else ran with the Compressor being disconnected. I told him that I never saw that fan run. The techs told him that it was because the Breaker was tripping. I told him that the Breaker tripped ONCE when they first started. The fuses also never blew after they started working, which also makes this Compressor thingy suspect to me. During the time that they wokred after they first did something tha made the Breaker trip, it did not trip again the whole hour that they tried stuff. They were asking me t ruen it on and off for them.

Manager called the Techs into his office in and they told him that it was not tripping all the way, inside the house. They never came into the house though. I would turn the breaker on and off when they asked me to. I abolutely know when it is fully tripped because you see red. I also know when it is a little tripped. It never tripped at all, but once, so I don't know for sure that the Breaker was the reason that the fan would not run after the Compressor was disengaged, as they said it SHOULD if it is not the Compressor.

I called back because they had said that if it was definitely the Compressor then when the Compressor was disengaged the Fan and something else would still run. They had told me that the wire coming off had NOT burned up the fa motor. Seems only the compressor. The Service manager told me that during the time that the fan Motor was (the one that got replaced) wearing out, the Compressor was running and not beneftiting from a cooling off turning blades. He said that he did not think that the wire coming off killed the Compressor, but that it was about ready to go out anyway. I was tired. I did not want to appear argumentative but I wanted to push the envelope by telling him that the Senior Tech last week had said that the compressor was strong, when HE tested it. So either the fallen wire shorted it out or not, in my mind

Or, The Service Manager may want it to be that the Compressor was simply worn out, because he has to know that if they had not scared me from having heir HVAC techs changethe Fan motor... fear they would break it because it was old and I would HAVE to buy a whole unit, had they not scared me I would not have had a layman doing it. The wire would have been properly secured and I would have air.

But the fact that noting did work after they disegaged the Compressor made me hopeful that something simpler was just not letting the entire unit get power. No hum from ANYTHING. I want to have a different Company take a look, But all people want to do is sell you a unit.

I think they get some huge Commission or something for selling units. No one want to replace anything. Like they scared me off from having them replace a simple 135.00 fan and it resulted in me... according to them, having a blown up Compressor. I KNOW that that Compressor was good last week. Him saying that the old Fan Motor took a toll on the Compressor sounds good, except that that Compressor had been tested and not run again until a new Fan Motor was in.

Do you know if after the wire fell off and touched the unit, tripping the breaker and blowing the fuse.. do you know of anything that might kill the power still, to the entire unit?

I don't think they are at this point being dishonest but one tech had 5 yrs. Experience and the other only three. The nicest kids you ever want to meet and they tried really hard, but I just do not feel sure.

You are right no one wants to clean up someone else's mess, but had they just TRIED to replace that fan motor before scaring me to let them, it wouldn't be any mess. Surely they could have come out and seen one way of the other if it would easily come off (Bolts unscrew) before warning me that they might break something off if they tried to remove it.

I just feel screwed. It turned out that the bolts were not frozen and now it appears duct tape killed my unit. It just seems so totally avoidable. I wish to God I had known his plans for that duct tape.

I printed Newspapers for Twenty Years ad ran a Team so I know a tad about mechanics and such. I would have KNOWN not to let him use tape as a permanent fix in that instance. He still does not know.
