Frigidaire front load washer won't spin or agitate. I did the diagnosis from the tech sheet inside the washer and everything checked out fine except the last step, where it says if you get about 6 ohms it is the spin control board. I replaced the spin control board($220.00) last night and did 2 loads of laundry, no problem. Put another load in this morning and it won't agitate or spin. It pumps out water no problem, just will not agitate or spin. What should I try next. Thanks for your reply.
