“What new washer will stack with my existing dryer? I have a Frigidaire washer that needs to be replaced. The dryer that I have is model LEQ7000ES0. I think a new washer model FAFW3801LW will be compatible for stacking, but want to verify before I buy, and if it is not compatible, what model is? Also, I have the original stack kit; will it work with a new washer or will I need to replace it as well?”
