Gas dryer vs. electric dryer parts

Both gas and electric clothes dryers require electricity to run, but gas dryers also require a gas hookup to generate heat. An electric dryer requires a 220V outlet, while a gas dryer will need a 110V outlet.The main difference between the two is how they heat the airflow to dry your laundry. Gas dryers use natural gas or propane to generate heat and electricity to power the drum, fan, lights and controls. Electric dryers use metal heating coils and are completely powered by electricity. 

Gas and electric dryers from Whirlpool brand offer comparable performance, innovation and convenience – and a variety of sizes/capacities and styles. Check the hookup in your home to find the right dryer for you.

What are the parts of a dryer drum?

What is a dryer drum? It’s the cylindrical part of the dryer and has baffles that lift and circulate the clothes. A drive pulley and idler pulley rotate the drive belt that wraps around the drum. The drum is supported by slides, glides or pad. A felt drum seal secures the clothing inside the drum.

What is a top load dryer?

While you may see certain models called “top load” dryers, they don't actually load from the top. They are meant to pair with a top load washing machine for a matching aesthetic. Both top load and front load dryers load in the front.

What are dryer arms? 

The arm of a laundry dryer connects the idler pulley wheel to the motor. The idler pulley wheel creates tension on the drive belt around the drum. It helps rotate the dryer drum to spin the clothes dry. A worn or broken arm will interrupt the dry cycle as it will impede the rotating drum.
