Baby swing won't swing or has stopped moving

A baby swing that stops swinging is usually a power, weight sensor, or obstruction issue rather than a broken motor, and most causes are simple to check.

Symptoms

  • Swing doesn't move at all when turned on
  • Swing starts, then stops after a few seconds
  • Motion is jerky or weaker than before
  • Sounds and lights work but the seat doesn't move

Likely causes

  • CommonDead or low batteries, or unplugged power adapterBattery-powered swings are the most common no-swing cause, especially if batteries haven't been changed in a while.
  • CommonBaby's weight below the sensor threshold, or seat emptyMany swings won't engage the motor unless they sense weight in the seat within a certain range.
  • PossibleSomething obstructing the swing arm's motionA blanket, toy, or the swing being too close to a wall or furniture can physically block the arc.
  • PossibleMotor gear worn out or jammedAfter extended use, the internal gear motor that drives the swing arm can wear down or strip.
  • PossibleSpeed/mode setting turned to off or a low settingIt's easy for a child or accidental bump to change the swing's control settings.

What to do

  1. Replace batteries with a fresh set, or confirm the power adapter is fully plugged into both the wall and the swing.
  2. Check the seat weight range in the manual; very light infants sometimes don't trigger the motion sensor on some models.
  3. Clear the area around the swing so nothing blocks the arm's arc, and check under the seat for stuck toys or fabric.
  4. Cycle the power off and back on, and try each speed setting to see if any produce movement.
  5. Listen for a motor sound when you turn it on; a humming sound with no movement suggests an internal gear or motor problem.
  6. Check that the seat is properly clipped or seated onto the frame, since some swings won't run if the seat isn't detected as attached.
  7. If it's an older or hand-me-down swing, check the manufacturer's site for the model's typical lifespan and known issues.

Tools and parts

  • Fresh batteries (correct size)

When to call a pro

If the motor hums but doesn't move the seat after ruling out obstructions, the gear motor has likely failed; for most swings, replacement is more practical than repair.
