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.
