The big box stores don’t have to eat the failures.
Have someone comeout and work on it and find that out.
Tthe parts don’t match-up with the manufacterures parts list and that’s how I found all this out from a person that works at one of the parts warehouses.
I do work on them and I did get parts (for the older one) at the appliance store parts desk (pulley; switch). No problem.
You will always hear the argument about brand-name superiority vs. generic in any industry. Very rarely is it true, except in the case where the generics i.e. drugs are sourced from a second-tier manufacturer.
All appliances, all brands, all parts have been cheapened. The era of 25-year appliance lifetimes is long past.
