why bernina electronic wheel won't turn and motor bogs down


You don't mention which model Bernina you have. If it is a Bernina mechanical, ie 930 Record, it sounds like it hasn't been cleaned or oiled in a while and the oil has hardened making it difficult for the motor to move the parts. Pick up some Bernina oil for "mechanical" machines, or for a quick fix a bottle of Tri-Flow Synthetic Oil at the hardware store. Following the diagram in your manual, put one or two drops of oil every place indicated (be sure to oil both the top of your machine and the area below the sewing surface). In your case, pay particular attention to the oil holes located nearest the handwheel. That is probably where the problem is worst. To help loosen things up, you can direct heat from a hand-held hair dryer into the interior of the machine. In the future, be sure to keep your machine cleaned and oiled on a regular basis. My policy is every time I change bobbins, after 8 hours of continuous sewing, or every six months if the machine has not been in use.

Where are the carbon brushes located on a Bernina sewing machine located? It is a Bernina Record 730, B2-730, EPI 2 - 40 -0803, 85/37 W 7250/min. Thank you.


THE MOTOR USUALLY HAS A LARGE SCREW. WHEN YOU REMOVE THE SCREW THE CARBON BRUSHES WILL SHOW. THERE IS USUALLY TWO. YOU CAN TAKE THEM TO A LOCAL MOTOR SHOP TO GET NEW ONES.

Bernina Record 930 Electronic, seldom use, like new. Wheel will not move. Was doing stright sewing, machine slowed down then froze. Maching is clean. No instruction book or manual. Machine belongs to my elderly mother who cannot locate manual.


Bernina 930 Records are notorious for the basting stitch sticking which eventually locks up the machine. To prevent this from happening, be sure to run the basting stitch for a few minutes every month. If it is stuck, you'll need to take it to a Bernina technician.

If it is not the basting stitch, it could be a broken plastic gear (trip to the Bernina technician) or it needs oiling.

If it is not a broken gear, then it probably needs oiling. Your Bernina mechanical requires regular oiling and cleaning even if you don't use it (ie, every time you change the bobbin, every 8 hours of sewing, or every 6 months if not in use). HINT: recommend Bernina oil or similar good quality oil for mechanical machines, NOT 3-in-1 oil, WD-40, or cooking oil!!! One or two drops of oil in every oil hole and every place that metal part rubs against metal part.

Treat your Bernina well and it will serve you well for many years.
