I'm afraid you're going to need to stomp your little feet with this particular 'technician'. Let him know you plan to contact the main parent company and report his lack of service if he is a licensed tech, maybe. I know of some here who have lost their approval to deal with particular brands this way. That or just find someone else! He's not one to inspire confidence in his work, I feel.

Bill him! I'm not kidding. I've done that before, and it works because then you are off their back. Then find someone else who will do it right. And let the sewing community know that this is not a place to do business. They will care when business starts dropping off.
My elderly serger broke a needle and threw out the timing. I couldn't find anyone to fix it, so ended up having to buy a new one. I'm still bummed about that, because the old one just did a perfect job!

I would be furious! so unfair.

One of my overlockers started making a terrible clacking noise a few years ago but still worked perfectly well ..(I had always oiled it - but never serviced)

I just ingored the noise.. kept oiling & sewing.

Then we moved. I set it up in the new place and next time I used it I couldn't believe how quiet it was. No more noise.
It's still a total mystery to me !

I would recommend a second opinion, but it doesn't sound like you have many techs to choose from.

good luck!

Thanks for your input Cuties...What do you think of my asking him to sell me a new serger at his cost? I took him a serger that sewed perfectly with a little screechy noise and he returns a serger that no longer will sew without the left needle thread constantly breaking (it gets wound around the right needle for some reason). Still can't get my head around how this could happen...Thinking I should not leave without a working serger, even if he doesn't make a profit on a new one or a floor model...Thoughts Cuties?

Take your refund, and check to make sure the needles are put in right. Believe it or not, this is many times the only problem. Make sure they both are put in as far as possible, the left needle will look shorter than the right. They are off-set to allow the looper to reach the right needle.

poor machine it dies after 25 years loyal service and you insist on the kiss of life.
I feel sure that it has earned retirement and the newer models do so much more than they did a quarter of a century ago. I guess they no longer even make spares for it. the dealer had serviced it in good faith and now when it breaks the poor man gets blamed for something that has happend to a piece of metal that has become brittle over the long years. perhaps he is not old enough to have met this particular machine before.
please do not maline him. all good work horses die eventualy.Give it a decent funeral and get a new one that will most likely see you out

So sorry about the "Bad Fix" your poor serger got.
I have seen some bad jobs, not for me but another Lady. Her Serger with a noisy motor went to the original dealer to come back with a new motor. The new pedal does not even reach the floor and they bypassed the on/off switch so the light only works when you sew.
The poor lady puts a low stool under the pedal.

Bad service...... and that's the reason I am afraid to take my sergers or sewing machines to a mechanic. I had a brand new Pfaff and took it to a mechanic and he took it apart and put old parts back in it when he put it back together. When I took it back to the dealer she called me a liar and said her mechanic wouldn't do something like that.

Obviously you have removed both needles and inserted them again in the correct order?
I can't remember how long I've had my serger, twenty five + years, never changed a needle in all that time.
(I know, I deserve a slap for that)
Anyway, I had it serviced, similar problem, when it came home, I broke my very first needle. (left side)
Thought I'd just replace it, no biggy. Man was I wrong!
Broke another needle, (left side) and thread kept breaking.

FINALLY, I got out the user manual and it said both needles had to be removed and (I think)I had to insert the left side needle, then insert the right side needle. (whatever it was it worked)

In all the years I had used my serger I NEVER knew the needles had to be "inserted" in a specific order.
I do hope when you read this, that it solves your problem and that is all it is.
Otherwise I'm out of ideas and I'll just shut my mouth. :-)

This is a good lesson. Always test your machine yourself before you leave the shop. I learned the hard way too.

I would take the refund and warn everyone I know not to take their machines there. Then i guess I would shop for a new machine, since it was 25 years old. Good luck, Susan

Next time your serger makes a noise, take it for a drive!!!!LOL. It might be something that is just a little offside, and the movement of the car is enough to correct it - or so it might just be. Mine also did that, and I took it to my dealer. When he tested it, before I left, there was no noise and there was no nose until it gave in. You neer know, hehehe*****
