There is a thing called a suppressor which is normally located in the foot control which has fused, you need to open the foot control and you should see a a small thing that looks liuke a fuse connected to the two terminals which you need to take out and discard because you don't need it any more, if you don't have on in the control then it will be on the motor which means you will have to take it in for repair.

Quest. abt. 1970s 830 Bernina.Just put a thermal switch into the foot pedal. Plugged into machine and electrical outlet,the light comes on but is not sewing.What can I do to troubleshoot further?


Perhaps carbon brush? If it is worn down and no longer making contact, it will not work.

If the motor is trying to run but not able to, then the machine is most likely seized due to old oil and no regular maintenance.

My Bernina "Record" of 1972 suddenly stitches away without foot pedal command, infact same with pedal unplugged Only way to stop is cut AC power


Something with in your machine seems to be shorting out. Since it is many years old I suspect you have wires that the insuation is rotten and making a short. I have seen this before. Should get it repaired if it's worth it. You could be shocked or hurt.

Bernina machine starts sewing anfmten stops or doesn't start at all.


Be sure that you regularly clean and oil your Bernina. If not oiled regularly, the old oil turns to varnish and actually freezes the parts. Some people believe something is wrong with the motor or foot control, when really it just needs some TLC to keep it running smoothly.

May be one of several issues--depends on the model Bernina. Could be a problem with the foot control. I had to replace a carbon brush in the foot control of my 930. (A new foot control could cost over $160!)

Or some machines (mostly older models, ie 830 Records) have carbon brushes on the motor that wear with age. Once they've worn down, they no longer make constant contact giving you the "intermittent" issue. I've replaced carbon brushes on some older Berninas--usually found somewhere around the motor (look for a screw or knob on the motor). You can buy replacements a lot of places. I've purchased them on eBay.

What to do when foot pedal just stopped working on old Bernina 830


There are a few problems possible. Assuming that there is not a mains (house) power problem, use the following logic to sort out the problem:
1. Do you have a light (assuming that the light bulb is good)? continue to #2.
2. With the machine unthreaded, the presser foot up, and the power cable plugs fully plugged in at the motor and foot control, depress the control to the run position.
Carefully bend and wiggle the cables at the plug locations one at a time. If the motor runs, the cable wires are damaged so you will replace the cable.
3. If available, try a (known good foot control) from another Bernina 830 of that exact vintage.
If the test foot control runs the machine, replace your foot control. Note: If the foot control is a type 213 for very old models, suggest that the control be replaced with a two wire electronic phase type control. (requires the foot control plug end to be cut off and rewired to the new phase controller). These electronic phase controls can be purchased from EBAY. Stay away from the Bernina type 213 control if possible. The type 213 controls have not been available for many years and it is highly likely that these controls are in a used condition, so you will not know if it has been properly adjusted.
If the 830 is a later model machine with the type 232 or 290 foot control and it is determined to be defective, no problem as they can be repaired.
4. If the (known good foot control) still does not work, you can assume that the motor has a problem. Motors for the Bernina 830 are occasionally available on EBAY and other sources.
Note: If the motor brushes have worn out and the commutator has been damaged, the motor is also salvageable.
-------------
Note: Always unplug the machine from the mains power when not in use as per Bernina instructions.

I have and old Bernina 830 and am trying to adapt a new foot pedal switch. The new plug is larger where it fits the machine. Is the wiring the same on the new bernina foot switch as the old? If so, I can...


unless the new harness and control is for a new style computerized machine the control should be the same, the different size plug is baffling me
