Modern technology is great except when it is wrong. The “check vent” light on our dryer came on. Checking the vent is easy. But moving everything out of the way, getting the ducting disconnected and reconnected is a pain. And, after all of that, I didn’t find any obstructions despite checking every bend and curve. I did, however manage to get covered in dust and lint. The machine likely mis identified what it was drying and though it should dry sooner or with less heat.
