The other day my washer made a popping sound. I started investigating and found the terminal on the back where the power cord attaches to fried, so I replaced that. The washer was working intermittenly but now the washer wont turn on at all. Also, the dryer will tumble but it wont get hot. Its an older frigidaire stack unit Now I'm trouble shooting the cause of this? Btw, the lid switch tests fine.
