The variable speed blower controller in my Carrier 58SXB100 furnace has
failed twice due to melted out solder connections on the circuit board.
Both times I have been successful in fixing this, but I would like to have a
spare controller on hand.
Problem is, Carrier has changed the design. the controller is now
integrated with the blower motor and a new wiring harness is also required,
total cost $936.
Anyone have (or know where I can get) the original style controller? It is
a 7" x 7" x 2" box with a 5-pin connector that plugs into the motor. I
have pictures if you think you might have a match.
Thanks to all the pros who contribute to this group.
