I'm working on a Tempstargas model NDF075B12G1 and I'm getting nothing. If I disconnect the 6 pin connector the blower will com on n stay on but once I hit the breaker at the furnace n try turning back on with pin in it won't do anything. Wat am I missing. N the board doesn't have an indicator light

    Do you know how to use a multi-meter? Start checking your limit switches-rollout, pressure, limit & vent switch (if applicable). Most likely one of them is stuck/bad. Also see if the 5amp fuse popped. Hopefully you shut the power off before monkeying with the board and molex connector
