There may be 2 household fuses or circuit breakers for the dryer.

breaker. If the problem continues, call an electrician.
Electric dryers require 120-volt power supply. Check with
a qualified electrician.
Use a time-delay fuse.

minutes of use.

Clean out pockets before laundering.
The dryer may vibrate if not properly installed. Check the

with the floor.
When balled up, the load will bounce, causing the dryer
to vibrate. Separate the load items and restart the dryer.
