For the last couple of prints I noticed a strange burning smell from my printer. The printer was functioning fine so I wrote it off as the filament I was using. However this morning I started a print and the smell was stronger. I looked all around and noticed the heatbed relay had melted and there was a small amount of smoke coming from it. The printer was still functioning fine.

I turned off the printer immediately.

Anyway, I was wondering if I can just throw a new headbed relay in there which is relatively inexpensive... Or was this caused by a bigger problem? Here are some pictures.
