In the picture below, you can see a string of 10 resistors used for DC bus voltage sensing. I think that the blue resistors (the original ones) are 400k/1W. The colors are: yellow, black, black, orange. One of the resistors got open, and I replaced it with the one you see different in the string, the one in the red circle. It's a 390k/1W resistor. The equipment worked well for a couple of hours, then the resistor in the white circle got open.
Do you think the new resistor could have affected the string so that a new resistor got damaged?
I think we have a variation of 10k in the string with the addition of a 390k, which leads to increase the current.
