Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! If the board has failed again after a very short period, you likely have a short or poor connection in the wiring that is causing excess current to be drawn and damaging the board. Can you post a picture of the burn spot, please?

Hi Kelly, I'm sending you the photo, I also got a mild shock from the chassis as I was opening it up, the power is off now, I checked the power supply connection, it looks good, all other wiring looks good also, thanks!

Thank you! That is a pretty high current burn, it arced pretty good! I suspect something is shorted on the left side inverter board and it may have caused the failure of the power board. What happened to the original board, the same thing?

Expert:  Kelly replied 1 year ago.

If everything looks good, it is going to be difficult to know what caused its failure.

First one burned way worse, how is it that the chassis gives a mild shock? Is that my short?
Expert:  Kelly replied 1 year ago.

Yes, something is shorted to ground, it could be on that board or another part.
