We’ve had a ceiling fan in the guest room for years that always worked fine, until recently—it started skipping speed settings or just not turning on at all. I checked the wall switch, the breaker, even replaced the remote batteries. Still no go. I knew it wasn’t completely broken because sometimes it would turn on for a second then stop. After some digging, I found a wiring diagram and remote reprogramming guide on https://www.manuals.online/ , which pointed out a common sensor error for that model. Resetting the sensor fixed everything. Honestly, I’m surprised how detailed the info was.
