“Which dryer models use stacking kit #STACKIT4X? Hi again, I had recently posted a question that was answered as follows below - I am interested in purchasing a compatible dryer to stack on my washer, which as you indicate uses the #STACKIT4X kit. Can you prove a list of dryer models (or link thereto) that would be suitable (i.e. go with #STACKIT4X?). Thanks again! Allison Answer to previously asked question: I see that you are looking to stack you Frigidaire Affinity washer, model# ATF6700FS1, and your Frigidaire dryer, model# BCEQ6700FS0. These are non-compatible models, meaning that they can not be stacked. The washer uses stacking kit# STACKIT4X and the dryer uses stacking kit# STACKIT3W. These are 2 completely different stacking kits and are not interchangeable with one another. I hope this has helped. Please do not hesitate to contact us directly for further information on on your washer or dryer, or by submitting your information via the Q&A forum on this website.”
