Question about Bernina Sewing Machines
Bernina 1130 - power circuit board L4200 0885 (220v) - two resistors blown/burnt - L126, L125. Wonder why they blew ? What are the resistor values to buy to replace them ?

I re-drew the schematics from the PCB-layout and did some backward engineering to determine the resistor value. The machine is now again in excellent working order.

SOURCE: I have a Bernina 1015,
Any resistor can fit in that position of the old resistor, you just have to ensure it is of proper fitting and size. Most of the time, it tends to be a capacitor that is burnt out and need to be replaced.
There are replacement circuit board and that should help you do the joband save you the arithmetic problems there on. You can get any type of resistor that carries the same resistance as the old one already does.
Most of these machines have 220V. I will strongly advice you replace the entire circuit switch in order to save time,and it actually is not expensive. The colours on the resistor actually do not really matter that much, it is for them not to get mixed up in the process of installing them on the board.
Hope this was helpful to you.
