A cooking appliance, such as a toaster or oven, has a lifting arm including ribs that form a support surface for a food product in a cooking cavity of the appliance. Each rib can include an opening configured to permit infrared radiation from a heating assembly to pass through the rib to the food product supported by the lifting arm and/or to reduce a thermal mass and capacitance of the lifting arm. The heating assembly can include a support and/or heating element with a curved shape having a concave side facing a cooking cavity. The support and/or heating element can have a planar shape when unstressed and a curved shape when stressed. The heating element may be coupled to the support so as to be slidably movable relative to the support, e.g., so the heating element can slide relative to the support.

A heater system for an LED light assembly having a lens includes a flexible composite positioned around an outer surface of the lens. The flexible composite includes a polymer base layer, a plurality of conductive buses provided on the base layer, and a resistive layer electrically connecting the plurality of buses to form a circuit.
