Fan on Yeti 3000 suddenly running very frequently

I've had a Yeti 3000 for several years now. It's always plugged into the wall and I use it to power a CPAP machine every night. About a week ago the fan started coming on every few hours for 5-10 seconds. Yesterday it was coming on every 10-15 minutes, again for 5-10 seconds. It is not notably hotter in my house now than it has been recently so I'm not sure what would explain this. Any ideas?
