I had mice in my blower motor and the garbage they dragged into the blower housing blew the thermal fuse on the resistor pack. So I soldered in a new thermal fuse. The problem is that the new fuse has shorter legs than the old fuse and is in a different position within the pack. Does this matter? Does a thermal fuse react to ambient temperature or really just the temperature of the wire? The new fuse is actually rated for 15?C less than the original, so I do have an additional comfort zone but do I need to have the new fuse in the exact spatial location as the old one?
