    New to forum and needing advice

    I hope my request for help doesn't violate the site rules, but I think I need the advice of a professional, and this seems to be the place to find them.

    Our five year old A/C unit went out (nothing would come on) this past weekend and to make a long story short, the tech that came out claimed that after he blew the transformer he had just replaced, he realized the problem was actually a bad controller board, a Carrier HK42FZ013. This was this past Sunday. He was to return on Monday after he got a new board and and new transformer.

    He arrived late yesterday and proceeded up to our attic. I was already a bit suspicious, but my instincts really started flairing when he was in our attic for almost two hours replacing it. Access to the controller board is fairly easy on our Carrier 58STA070, so I couldn't understand what the problem was. He finally got the unit operational, I paid him and then asked for the old board. He first told me he had already taken it out to his truck, and when I said I'd like to have it, he refused, saying he couldn't let me have it - company policy. We were still inside the house and I could see the box on top of his tool bag despite what he had said and, well, I took it and refused to give it back to him. I figured it was still my board, whether it was a dead one or a live one. Of course my suspicions deepened as he insisted I return it to him or he was going to go up to our attic and remove the "new" one. I was polite, but explained to him that that simply wasn't going to happen and invited him to call his boss or we could call the sheriff, but he wasn't leaving with my control board. I have the board.

    My suspicion is that I now have in my possession a perfectly good control board. I even wonder if I am holding the brand new board that, after discovering it wasn't the problem, he continued to trouble shoot. That's the only reason I can figure why he was so adamant about leaving with it (and perhaps cover himself in the process).

    Anyway, I am hoping somone here can offer me some guidance on what I can and should do at this point.

    Regards,
    Scott

    you need to remove your prices....

    But your situation definately raises a red flag....

    I would call the contractor in the morning and speak with the manager. Explain that you are unsatisfied with the service and would like a partial refund. You may not get it all back but you may get some.


    And get a new contractor. Personally, I have no problems leaving failed parts with HOs that want them (provided its not a coil or compressor).....but a contactor or board....sure you take it. Less trash in my truck.

    The fact that he didn't want to give it to you is a little off. You may in fact be holding a new board.....If you want, you may be able to contact Carrier or the supplier and read them the model off the board. It may lead to some interesting information.



    I'm sure others will be along with thier two cents. But thats mine for now. I will probably chime in later with others.
    I fully support the military and the War on Terrorism.


    If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

    If you do know, then do. But do it right. Otherwise, you may not be doing it long.

    What if it has an E instead of a 3.

    How many times must one fix something before it is fixed?

    Yes, dj3901783, there is a 3 amp [ or an E or W or an M to some of you ] car fuse just to the right of the contact screws along what I would call the bottom of the board, if oriented as to read the printed labeling.

    That fuse looks to be fine.

    As for board itself, It's hard for me to detect any evidence that the spade connectors have seen any use. There is one that has a plastic cover on it that when removed looks exactly like the others.

    Is there any easy way to find out who the local Carrier distributor is and do you think they might be able to help? I spoke with Carrier Corp yesterday, and didn't find them very eager to get involved.

    Unless you can see a manufacture date. You still don't know if thats the new or old board.

    Yes, I agree. That's why I'm seeking out the advice of serious professionals. I studied the board and asked Carrier hoping to find the date of manufacture. My thinking was that would be the easiest way of proving out (or disproving) my concern. I would much rather go that route that placing this board into the unit and seeing what happens. Then, it will likely show evidence of having been installed and my case becomes weaker.

    Setting aside that the 3 amp fuse also looks like an E, do you know of a way to determine the date of manufacture? Or in the alternative, some other approach I might can take to allay my concerns?

    Post the boards mod number, and any revision, or serial numbers that are on it.
    Someone may be able to tell from that.

    Have you called the owner/manager of the yet?If not,why not call?

  13. #13
    I called them about an hour ago. Asked for the manager whose name I had found (this is our local Service Experts affiliate), but was intercepted by the service manager. He was already aware that the tech had refused to give me the part, saying that in North Carolina, where the tech came from, they had strict policies (I think he meant the State) about leaving parts behind.

    Anyway, he has offered to send a different tech out to stick the board back in the unit to see if it works. I don't know why, but my instincts tell me to stall them. Unfortunately, I seem to be getting stalled by Carrier as well.
