Welcome, Toaster User! You're here for tech support, because let's be real, your toaster's been on the fritz.
Try turning off and on the toaster. Like, really.
Check your toaster's manual. No really, check the actual manual, not just the one on your phone.
Unplug it. Plug it back in. Unplug it again. Plug it back in again. Repeat as necessary.
Call in a professional. But let's be real, they'll just charge you an arm and a leg.
