I've never had that problem and I've had these heaters on every car I've owned in the last 25 years. The only way your heater door would get that hot is if you had it connected directly to the manifold cover, and that isn't the way they are installed. At least none I've ever seen. But the cable is a good idea, because those doors aren't easy to reach from the driver's seat.
