review of the singer 4423 heavy duty sewing machineThe SINGER 4423 Heavy Duty Model Sewing Machine features a powerful motor, a heavy-duty metal interior frame and a stainless steal bed plate. According to the manufacturer this is a heavy-duty machine that can sew through just about anything. Not all of the customers that purchased this machine would agree with that however. (More on that in a moment)


The SINGER 4423 has an automatic needle threader, a drop in bobbin with a clear view cover, a one step buttonhole feature and it comes with a number of accessories. Accessories include an all-purpose foot, a zipper foot, a buttonhole foot, a button sewing foot, bobbins, a pack of needles, thread spool caps, and a soft sided dust cover.

The Reviews


We mentioned earlier that the manufacturer says that this machine is able to sew through just about anything you throw at it but there are plenty of customers that disagree. When researching the SINGER 4423 Heavy Duty Model Sewing Machine we found nearly 200 user reviews online and this product received a very disappointing average user rating of 3.47 out of 5 stars.


We’ll start by mentioning some of the things that positive reviewers liked about this machine. One customer said that they do a lot of quilting and the 1000 stitches per minute can’t be beat. In addition to the speed of the machine people also like the automatic needle threader and several people commented that this machine is lightweight and easy to transport from one location to another. Some people even said that they were able to sew through some thick materials like canvas and denim. However, there were a large number of negative reviews from people that scoff at the claim that the SINGER 4423 is a “heavy-duty” machine.


One customer said that they only had the machine for about five months and they only used it maybe 6 to 8 times when the automatic threader broke. Another person said that the machine worked like a charm on their first four projects but on their most recent project, which happened to be a very lightweight leather, the machine was no longer able to make secure stitches and they kept getting loops on the underside of the material no matter what they tried. Another customer said that the motor burned out after just four months. Someone else said that the machine broke in less than one month and one customer said that this machine is certainly not heavy-duty and it is not even light duty.


One customer initially left a very positive 5 star review but within three months they started having a few small problems here and there. After a few more weeks they started having major problems and they eventually came back and changed their 5 star rating to a 1 star rating. Another customer said that they have been sewing and quilting for “Many Many years and I’ve NEVER had as much trouble as I do with this machine”.


There are some positive reviews online for the SINGER 4423 Heavy Duty Model Sewing Machine of course but there are so many negative comments that if you are considering purchasing this machine we would recommend that you immediately reconsider and start looking into and alternative machine.

    I’m sorry Singer machines had so many negative reports. I purchased a Singer machine in the 1960’s and used it to make most of my three girls’ clothes, even prom dresses, for more than 20 years. The standards for the working parts of the machine surely changed.

  3. Donna says:

    I too have had problems with this machine. It broke down on me just months after I purchased it after which I had it repaired. The repairman said the timing was off. It has now broken down on me again and I am done with it. I would rather put money toward a new machine rather than repair this one again. I would advise anyone NOT to buy this machine.

  4. Sandra says:

    I have had, and used, this machine for about a year and a half. The only problem that I have run into is the thread take-up leaver is not a smooth pitem. The thread catches in some of the edges and causes it to break or jam. Other than that, which some would consider major, I have enjoyed this machine.

  5. Susan says:

    I purchased 2 Heavy-Duty Singer Machines for my Business. I have always had Singer machines and used to Love them, until lately. I also teach Sewing/upholstery classes at local highschool; and helped the school choice/purchase new machines for the class. We purchased 2-Heavy Duty-Singer machines and 6 Standard-Singer Machines. I have not really noticed a big difference in the machines and the students have little problems adjusting to either type of machine. My home Heavy-Duty Singer sewing Machines have given me lots of problems with heavier fabrics and leather materials. And this was the Main reason I purchased the machines..The Singer machines are made a lot cheaper now and parts are mainly plastic and not heavy-steel materials that last and don’t break down as often. Yet the prices of the machines seem to keep on going up.

  6. Noel says:

    I received my Singer 4423 as a gift and it’s working great. I’m very happy with it. I watched a lot of tutorial videos to be sure I was using it correctly. I haven’t had any problems.

  7. Audrey says:

    this is not heavy duty, too fragile.

  8. Ohoyo Tohbi says:

    I purchased this machine last month (April 2014). I can sew by hand fair enough from what my grandmother’s taught me and I was very excited to finally have saved enough for a machine! I made my purchase at JoAnn’s Fabrics after speaking with a store employee at some length. I had browsed the machines prior to purchase. I even attended a sewing volunteer event with some ladies in my community to get their advice! My first project was/is a multi-fabric back to back black-eyed Susan pattern for a table covering to be part of a traveling display where I volunteer. One fabric is knit, the others are woven. Only two layers at a time. This should not be a hard task for this machine, right? WRONG!!!! I AM SO VERY DISAPPOINTED WITH THIS UNRELIABLE INVESTMENT! I’ve done everything I can to get the bobbin situated without having it bunching and jamming. I’ve read the manual, the quick start guide and the manufacturer’s website until my eyes crossed. I’ve watched multiple videos. I’ve changed bobbins multiple times. I’ve changed needles. I won’t be able to utilize this darn thing at all. A COMPLETE LET DOWN, SINGER. No offense to readers but to Singer, WTF, really. :(

  9. Sherry Sharpe says:

    For some reason I’ve always had singer machines. After reading what Ohoyo had to say I realized all of the singer machines I ever had always ended up with the same problems.
    The thread always bunched and jammed up the machine. After this starts happening a lot of other stuff starts going wrong and it’s time to through it away.
    The last one I had needed to be fixed a month after I brought it. It lasted 2 years.
    Now it just will not sew. I will never buy another singer.

  10. H.L.Mali says:

    Button hole stitching is possible only after button hole lever pushing back to move cloth back and again reaching width of button hole size marked on cloth button hole lever has to push or pull forward. then wide stitches. remove cloth as it is ready. Problem it is not going backward but does not automatically and moving forward and stopping after wide 6 stiches.

    Second problem is that there no cloth to cut slit as while moving to and fro needle does not create gap of half mm or 1 mm and vertical 3 lines are made instead of 4 lines of stiches keeping gap of half mm or 1 mm to cut hole.

    Please advise what to change buttonhole foot for touching button hole lever reaching top chalk mark and down chalk mark automatically.

    Please also advise how to develop gap of 1 mm between two vertical line of left and right stitches. All the rest functions iare ok.

    Expect reply to

    Your guidance is appreciated.

    I just purchased this machine brand new to use while living in Singapore. Took it out the box was sewing some darts and realized the needle position was off. So, I pulled out the manual and went to adjusting it. It would not move. It is broken. Also I noticed upon checking out other switches that the feed plate switch didn’t work either. I called Courts who I purchased and had deliver it to me cause I don’t have a car and they referred me to their tech who wanted to charge me $33 for a house call. I haven’t even used a full 10minutes on the machine. The machine cost $500 +….. NOT HAPPY

  12. Jackie Joan says:

    I bought this machine to do ‘light’ heavy duty work, so as not to stress my Janome Horizon or Pfaff 7550. Basically, it was a waste of $500. While the motor is heavy duty, the machine does not perform well. I have used it for quilting and some light leathers. It is noisy and rough. My biggest problem is that it either skips stitches, or leaves loops in random spots. For example, on a 36″ seam, 30″ is probably perfect, and the other 6″ will have loose loops. I am very familiar with sewing machines, and quite competent when it comes to adjusting tension, pressure foot pressure, etc. I change needles often and clean after every use.
