Circuit Board Repair

Well I was again in a hurry and cross wired the norCold fridge. Then I remembered something about getting the 12v+ and ground reversed is very bad. Indeed, dead with Scr code, "not user servicible". So I took out the set of boards for inspection. All three fuses were OK That would have been easy. Instead I found the solder line on the board from the "gnd" to pin 1 blackened and no conductivity. Like it fused. Pin 1 goes right to ground. No other sign of damage and a random check of conductivity for near by lines test OK. So.... I want to solder a jumper between the mounting pins rather than just trying to buy a new set of boards. There are two. Any thoughts?

It can be done. Just use a small soldering iron so as to not lift the line you are trying to extend. Use flux and small solder.

If your lucky the board has a diode on the +12 to prevent any damage. Won't hurt to run a jumper wire and try it. But if you burnt a trace it was pulling some current, and that current had to some somewhere. But cross your fingers and give it a try.

I would cut and lift any portion of the foil that may be loose just to insure it never causes a problem in the future. This is just a clean up idea.

The board may have a coating over the foil so try a test solder somewhere to make sure solder will take. If a problem try to solder directly to the lead of the first component in the path that opened. You can make a good mechanical joint on the lead and then solder the jumper to the lead.

The foil (trace?) did not pop thru the epoxy layer. So I put a 18g wire jumper across the space, connecting the pins. Fridge seems to be happy so I am I'm good to go. It took several attempts as even the small iron seemed too hot.

A "authorized service center" fit would likly have cost me a few hours labor and a new board. Thanks.
