AppliancePartsPros are exactly that. My appliances are Kenmore brand so I expected trouble in finding a light cover and an aluminum filter. Not so!
Any part you consider has a cross-reference system to show which of their products are compatible with your appliance. No guessing. You can speak or text with a very helpful Parts person, and on my appliances, a video of installation showed us how. Easy Peasy!
This is my 2nd purchase from those fine folks. We also repaired the plastic upper rack roller system on my Kenmore dishwasher with a much sturdier metal roller system recommended by the customer service rep.
I highly recommend that you give AppliancePartsPros a look!
