I've got a tech the fans not running, when I test the pins on board I get 0v. I test with meter grounded to chassis and pos to the pin I get 23.94v, so when I ground the neg lead of the fan the fan works! seems like a simple fix, does anyone have any concerns or issues with this?
This is usually a bad Q5, which takes the fan low to turn it on. Short the E-C together and if the fan comes on, and there is a Fan_En signal present at the base, then Q5 is shot an needs to be replaced. This is not uncommon for TBeam.
