Terminal Block and Power cord burn out!

Dryer Repair
1

The power cord wire that connects to the top terminal block shorts out which causes the line to burn and a open line occurs which stops the dryer. This same problem happen about a month ago and the repair man put in a new power cable and a new terminal block and it work fine for about a month, and has now it has shorted out again. What would cause this to happen twice and how can I check to see what is causing the problem.:confused:

Thank you,

There may be a loose or shorted connection internally. First place to check would be right where you’re seeing the scorches at the terminal block.
