My admiral capacity plus won’t spin. Smelled a burning smell as well. The belt is intact. When I pull the belt off and turn it on the motor (front right) operates. I can turn the tub by hand with the belt off. THe motor in the right rear (pump motor?) makes a ratchety noise when I turn it by hand. If that is bad, would it keep the tub from turning?
A bad pump could cause your problems. Maytag has redesigned the pump, presumably because of problems like yours. Here is the tech bulletin on the new pump.
