Most coils on an electric dryer can be replaced by detaching the wires from the thermostat, thermal fuse and coil. The coil is typically secured to a can in the dryer and slides out so a new coil can slide into its place. The coil needs to be screwed back into the can and the wires from the coil, thermal fuse and thermostat need to be re-attached.

Homeowners can troubleshoot problems by checking the heating element and the coils within the dryer when it is not producing heat. For example, when heat is not produced, the radiant sensor may need to be checked on a gas dryer or the thermal fuse on an electric dryer. The sensors provide power to the coils and monitor the progress of the igniter on a gas dryer. If the sensor and thermal fuse are fully operational, the coils have likely worn out and need to be replaced.
