One of the solders on the back is burnt really badly. Left a 3/4 inch burn mark on the plastic cover. The flip side of this burnt solder is a relay box ( http://www.mouser.co...Kz4NLJcTSVoPbo= ).
Is it possible to resolder this to fix or is it too burnt out? Also, is this most likely the cause of the heating problem or could it be some other problem and I still have a bad heater?
I included pics of the front and back of the board showing which relay the burnt solder was under.
