I have an electric dryer (30A, 240V) that made a "pop" sound the other day and tripped the breaker. When I reset the breaker and turned the dryer back on, I saw arcing behind the dryer. Upon investigation, it seems to be coming from the plug contacts with the dryer.
Question: how do I repair this? Do I just need a new dryer plug? Do I also need to replace the contacts on the dryer?

I think it's worth just replacing - it'd be too much risk to try and reuse it now.
It appears to have been a loose or bent screw or connection on the left terminal. Replace the block, check the wires to ensure that they aren't fried (they appear to be fine from here), and reconnect.
