jump the wires...i used a piece of speaker wire...and both fans turned on...maybe you just got a bad switch...see if you can return it.

Hi,

Did you jump the thermo sensor wires as others have suggested? I've seen several other threads where a new thermo sensor was bad from the vendor. If jumping wires works, your new thermo sensor is bad.
