Step 1 · Disconnect Power

Before performing any work on the dryer, it is crucial to disconnect the power supply. For electric dryers, this involves unplugging the unit from the wall outlet. For gas dryers, which also use electricity for the motor and controls, unplugging is sufficient. If the dryer is hardwired, turn off the corresponding circuit breaker in your home's electrical panel. Always double-check that the power is off by trying to turn on the dryer.
