Sunbeam toaster 3806 won't stay down and of course won't heat bread.
I have done this a couple of times over the years. Often, it is caused by an accumulation of crumbs around the thermal shut off sensor. This causes the toaster to shut off quicker because it gets too hot.
The fix it is unplugging the toaster, taking the outer shell off and cleaning all visible residue out of the toaster. Compressed air, wooden skewers, and slightly damp, lint free cloths are helpful.
Reminder: if wiping with damp cloths, please let toaster thoroughly dry before reassembly.
This was from another site but is the same as I would say or instead of the sensor, when you push down the handle, you are making a magnet circuit by putting the last part of transformer frame into place - a jammed piece of old toast can prevent this and then your toaster won't work. Unplug it, take it to the garbage can or the sink and pull our the crumb trays and after that, within reason give her a good shake and see what you dislodge
