Things You'll Need
It is a good time to clean the lint from the dryer exhaust port while you have the lint duct removed.
The spec sheet and wiring diagrams for the dryer may be attached to the inside back panel. Be sure not to lose these while working on your dryer.
Always disconnect appliances from their power source before attempting repairs.
The heating element, thermostat and other heating-related components can be found inside the back of most dryer models. For this reason it is necessary to know how to remove the back of a dryer. The back panel is removed the same way on most common dryer models.
Unplug the dryer power cord from the dryer wall outlet. Pull the dryer away from the wall so that you have room to work behind the dryer.
