Burned wires, Melted plastic

I was getting MinTemp errors and found burned wires on the heat bed power wires.  Plastic is melted where the connection is made on the circuit board.  Has anyone just gotten a specific replacement part such as this and soldiered it yourself?

hey @grandpa-joe,

I had this problem 2 times in about 3 weeks probably because the strain relief of my heatbed-cable wasn't done proper by me. After this, I soldered the wires directly to the mainboard and since then, I never had any issues. (and I 've made the strain relief correctly)

Thanks.  I ended up with a new circuit board and a new heat bed.

Just be careful and try to avoid what caused it.  This could result in a fire.  I burned up one controller board.
