A mica board heater has a mica board support plate assembly that isolates the mica boards from the frame of the heater. The mica board support plate assembly includes a mica board with openings sized to receive ends of the mica boards that support the resistance wires. The mica board with the specially sized openings is supported by a frame that is attached to the heater frame. By using the mica board support plate assembly, the mica boards are electrically isolated from the frame and without compromising the structural soundness of the frame.
