Agree with you - +1 to the coupler/bearing checks. Also make sure the jar is fully seated and the blade base ring is snug; a loose base or flattened/missing gasket can let the blade drop enough to make the coupler chatter and sound like grinding. If you see black rubber dust on the base stop running it until you replace the coupler or blade assembly so you don’t strip the motor shaft.

Also check any attachments you’re using; concentrators and diffusers can restrict airflow and make the overtemp trip especially on high heat. Run high fan with lower heat if you can - low fan plus high heat is the easiest way to cook the internals. If you’ve only been cleaning the screen and pull the rear grill and vacuum or blow out the motor cavity, as lint often mats beyond the filter. After a trip, let it cool completely before restarting or it will shut off faster each time.

First thing I honestly would rule out is a stuck power button. Give it a dozen firm clicks, then hold it down a long time and wait which, yeah... count slow. If it is an e‑ink screen it can look on even when it is off, so do not trust what the page looks like. I would also try a different cable and wall plug and let it sit for at least an hour, then do the long press again. If it was in a backpack in winter or a hot car, let it sit at room temp before charging. If it ever got splashed, stop charging and let it dry completely. If none of that changes anything, it is probably a battery or port failure and needs a repair shop. Frustrating, but fixable.

Yes, an app‑controlled feeder can be reliable for two cats if you pick one that splits meals evenly and feeds both at the same moment. That timing helps stop the usual bowl raiding, and a decent motor path plus a covered hopper keeps medium kibble moving without much fuss. HoneyGuaridan two-cat WiFi feeder is a solid fit. It runs on dual power so you have battery backup during outages, and the 5G WiFi app lets you set precise schedules and portions. The splitter drops the same amount into both bowls at once, which really cuts down on stealing. The app shows a feeding history and sends low food alerts, and in day‑to‑day use it handles standard medium kibble reliably. A couple of quick tips from experience. Measure your kibble so it is not oversized puffs and do a few dry runs while you are home to dial in portions. Place the bowls a little apart and use slow feed if one cat inhales food. Check the hopper weekly and keep it at least a third full so the auger always has something to grab.
