I have a Whirlpool top-freezer (model wrt549szdm00). My freezer temp is at 15F, fridge is at 50. It's been this way for a couple days now. I took the freezer apart, and there was no ice on the coils. Ice maker still works, but I've turned it off.

Occasionally, there's a really loud thumping sound, like someone throwing a plastic toy at the inside of the fridge. It usually happens in a series of 3 or 4 times, once every 45-60 seconds, at random times throughout the day/night. I'm not sure what's making that noise; I turned off my ice maker and it still happened. Sometimes it's quieter than others, for example in one series of 3 thumps, the first two will be loud, and the last one quieter.

Could this be a damper/diffuser issue? Or something totally different?

    If it was a damper or diffuser, I would expect one compartment to be warm and the other cold. They are both much warmer than they should be. 50 refrigerator is not safe. 15 freezer is safe but far from ideal. The big question is whether this is a thermostat problem or a functional problem (e.g., compressor). Commented Oct 30, 2023 at 18:21

    If you can move your food to some other fridge and defrost this one for 24+ hours that might be diagnostic. I know that's inconvenient. But no ice on the coils does not eliminate the possibility of ice in ducts screwing things up...

Just an update for anyone looking:
I was able to fix this by replacing the evaporator fan motor. Has been working since November 2023, shortly after my original post.
