Searspartsdirect.com is the recommended source for dryer heating elements that need to be replaced on Kenmore units. Amazon.com carries a variety of heating elements for consumers with Kenmore, Whirlpool, Frigidaire, Maytag, Samsung and other dryers.
The heating element in a dryer includes an un-insulated metal conductor that heats as electric currents pass through it. Over time, insufficient airflow in the element compartment, failure of safety devices and power surges may result in elevated temperatures that burn the coil out.
Homeowners can further protect their dryers from overheating by regularly cleaning vents and periodically checking the thermostats to ensure they are in good working order.
