Abstract: A heater assembly (10) is for installation in a clothes dryer (D). The assembly includes at least one open coil heating element (12), and a plurality of insulators (16) to each of which a convolution of the coil is attachable. The insulators are mounted on a support (22) in a spaced relation from each other. The support is attachable to a multi-sided pan structure (30). The pan has sidewalls (32A, 32B) to which the support is attachable for installing the coil in the pan. The pan has a lip (54) which extends beneath one end (54) of a heating unit (U) section (S2). The pan is directly attachable to the unit and the unit directly installable in the dryer. The heater assembly is also formed to help install the unit in the appliance during its manufacture.
