Also pop off the front grille and clear lint or product gunk there - blocked exhaust bakes the thermal cutout as fast as a clogged rear screen. If you’re using a concentrator nozzle or diffuser try a few days without it and finish each use with 15–30 seconds on cool to purge heat. Any burning smell, browned plastic, or the fan slowing on cool are red flags - don’t keep cycling it, go for a warranty swap.
One more angle which, yeah pay attention to grain direction and place the long edge along the grain so the sheet curls less during big wet-in-wet washes. Keep the sheet horizontal while drying and if it domes, flip it and mist the back very lightly to counter the memory. Pads that use a clean tear design look tidy in 9x12 and 12x16 and no deckle fuss.
