Claim 8:
9. A method for controlling a furnace, the method comprising:
operating a burner, the burner configured to receive and ignite a supply of combustible gas and produce a heated air, the heated air defining a temperature;
sensing, with a shape memory member, the temperature of the heated air, the shape memory member having a first fixed end and an opposite, second fixed end; and
actuating, with the shape memory member, a switch communicatively connected to a control board of the furnace, in response to the temperature being greater than a threshold, the switch being arranged within a plane containing the first fixed end and the second fixed end, wherein actuating the switch further comprises transforming the shape memory member from a retracted position to an extended position, and in the extended position, the shape memory member directly engages the switch.
