Why is one mixing blade not moving? - Black & Decker B2300 Bread Machine

Sounds like you need to take the part that isn't moving out and clean inside the whole good. I have use oil in mine so it would agitate and mix the ingredients. Hope this helps you

if cooling light is coming on ck to see if chill plate is getting cold after a few minutes , also visually verify that agitator blades are moving mix around and over chill plate

(chill plate is inside round tunnel that mix bars go thru )

You need to undo the screw to lift the head up.

The blade sounds like it's jammed somehow perhaps simply with some food matter.
Ensure the mixer is not plugged in then try removing the bowl, locking the mixer in the down position and pushing up hard on the blade to try and dislodge it. If it comes free and lifts up then try wiggling and rotating it normally off the mount.
Sometimes with use the attachments can become slightly warped requiring more force to lift them before rotating off the mount.
I once used my own Kitchen Aid mixer with the dough hook attachment to make a whole wheat bread dough. When I was done the hook was a bit bent from the hearty dough. There was also some flour in the mount causing it to jam. Removing the hook attachment proved difficult but not imposable.
Good luck.

I expect the teeth are stripped on the plastic drive shaft or the motor has seized.
Time for a new one I guess.

You are using too much water.. Dough is too wet. Mixer blade is just drilling hole in dough instead of moving it around to mix.

Be sure to measure exactly to recipe. This is science not art.

Your machine needs servicing .

It can't be repaired. If machine is under warranty try to get a new bread pan. If not, try calling manufacturer to see if you can buy a new one.

belt broke or sliping..
