I found whirlpool part # W11197766 which I believe is the the lower door latch assembly for my model. Is this also the assembly for the upper door latch? I would like to order 2 if that is the case.
For model number WMH53521HZ0
Hello Rick, thank you for reaching out. Yes, the upper and lower door latch assemblies use the same part number, FIX12349017. We hope this information helps!
