The best way to solve this would be to test the electronics with an ammeter and check all mechanics for binding. Theres not a whole lot going on down there, so should be simple to diagnose/fix.
Best guess would be that the motor is weak and has to draw more amps to do the same amount of work, or that the mechanics need some lube.
