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?
