    works but noisy and electrical connections in a bad spot

    The replacement for the original part is lighter and about half as thick which is good. My furnace is now working again and I am thankful for that and will keep the part on until I change the furnace. When the switch opens and closes you can easily hear the clicks even from 20 feet away upon startup. The electrical connections are located on the flat side of the unit not allowing quite enough clearance for the wires but it can be wedged into place.
