Display does not light up on PFAFF 1475 CD
These instructions apply to PFAFF 1475 CD. They may also work for other machines.
If you have some advanced electronic repair skills and tools, check the following:
For 220 Volts models - there is a fuse next to the power input, make sure it is good. There is no such a fuse for 120 Volts model.
If the fuse is Okay, you have to get access to the main circuit board by removing the bottom cover.
Check the primary on the transformer for 120 V AC (220 V AC respectively). Check the secondary side for 5 V AC (luminescent display), 9 V AC (turns to 5 V DC by rectifier, 4700 micro farads capacitor and a 5 V regulator STI L387A) and 28 V AC (turns to 35 V DC by rectifier and 2200 micro farads capacitor.
Pay attention to two soldered round fuses in series with the secondary 9 V and 28 V - both should be good. On the big capacitors you should have 9 V DC and 35 V DC.
Common symptoms for bad small 22 micro farads capacitors next to the some of the IC's - there are 5 of these: These capacitors are in parallel with 5 V DC.
## All of the LEDs light up but the display is blank
## All of the LEDs light up, the display is blank, and after a minute no LEDs at all
## No LEDs nor display.
Replace ALL five 22 micro farads capacitors using a good desoldering pump or desoldering station!.
Enjoy your resurrected PFAFF 1475 CD machine!!!
I just did this procedure on my aunt's one (Made in West Germany around 1990).
My Pfaff quilt Expression 4.0 feed dogs will not go down. The switch will not lower them.
I assume the switch you are talking about is the one on the front bottom of the machine. this switch should not slide back and forth easily, if it does than the linkage has been disconnected or broken. To check this you need to open the bottom of the machine and see what happens when you move the switch. To open the bottom you will need a torx screwdriver. First remove 4 long screws that go through bottom and into back, than remove two shorter screws that go through bottom into front cover, next remove 3 short bolts that hold the bottom to frame. If you can't see anything broken or loose after opening the bottom, you might need to remove the covers.

When free motion quilting with my Pfaff 2036 the tension needs to be adjusted frequently. Do you have a solution for this?
When experiencing tension issues, especially "long eyelashes" on the back of your quilt while free motion quilting with your Pfaff 2036, there are several steps you can take to troubleshoot and improve the situation. Here are some suggestions:
- Clean and lubricate your machine: Start by ensuring that your machine is clean and properly lubricated. Dust, lint, or debris can affect the tension and cause issues. Follow the manufacturer's instructions for cleaning and maintenance.
- Use the right thread and needle: Ensure that you are using a suitable thread for free motion quilting. Threads designed specifically for quilting tend to work well. Additionally, choose a needle appropriate for the thread weight and fabric type you're using. A needle that is too small or too large for your project can affect tension.
- Check the bobbin tension: While the bobbin tension is usually factory-set and doesn't require frequent adjustment, it's worth checking to ensure it's not too tight or too loose. Make sure the bobbin is wound properly and inserted correctly. If necessary, consult your machine's manual for instructions on adjusting the bobbin tension.
- Experiment with the top thread tension: While you mentioned keeping the tension around 1-2, it's worth experimenting with slightly higher or lower tension settings to find the sweet spot. Each machine and project can have different requirements, so don't hesitate to make minor adjustments to achieve balanced tension.
- Test with scrap fabric: Before quilting on your actual project, it's a good practice to test the tension on a scrap piece of fabric sandwiched in a similar manner. This allows you to make adjustments and fine-tune the tension without affecting your main project.
- Check the threading path: Double-check that the top thread is threaded correctly through all the necessary guides and tension discs. If the thread is not seated properly in the tension discs, it can cause tension issues. Consult your machine's manual for the correct threading path.
- Slow down your stitching speed: Sometimes, excessive speed can contribute to tension problems. Try reducing your stitching speed and see if it makes a difference in the tension and stitch quality.
- Consult a professional: If you have tried the above steps and are still experiencing tension issues, it might be beneficial to consult a professional technician or your local sewing machine dealer. They can examine your machine and provide more specific guidance or perform any necessary adjustments.
Remember that achieving the perfect tension can sometimes be a trial-and-error process. Take your time to experiment, make small adjustments, and practice on scrap fabric until you're satisfied with the results.
