Can you still use a dryer if it doesn’t spin?

Don’t use a dryer if the drum ain’t spinning right. Here’s why:

  • Clothes won’t dry well: Without spinning, clothes don’t tumble, so they won’t dry evenly.
  • Fire risk: Clothes can overheat and stay in one spot, which can be a fire hazard.
  • Dryer damage: Using it like this can mess up parts like the drive belt or drum rollers, leading to more expensive fixes.
  • Waste of energy: A non-spinning drum means the dryer runs longer, wasting energy and hiking up your bills.

If your dryer’s drum isn’t spinning, stop using it till a pro fixes it. 

It could be a broken drive belt, bad idler pulley, worn drum rollers, or a faulty motor. 

Using it in this state is unsafe and will likely cause more harm.
