    Furnace not running properly
    My furnace is one year old. 90% eficient Concord. PVC exhuast. BLower keeps running but does not ignite. This is happening more frequently. Weather seems to be a factor. Excessive winds; etc. Had a furnace guy out and he said pvc pipe to high. Changed that and it seemed to work better for a while. Tonight I have to hit reset every hour. Otherwise blower keeps running and never ignites. It has never been this bad.

    Call the company that installed your furnace. You bought it from them and there should be some warranty left.

    Usually when the blower runs and no ignition it is a sign of a overheat situation.

    Look on the cuircuit board and count the number of blinks when you restart after a failure. That info will narrow it down.

    I have a number of questions, first is the venting the correct size and length for your unit, and the issue here looks to be that the inducer runs and does NOT make (close) the pressure switch to continue the ignition cycle... thus... the burners do not ignite. Call back your furnace compant ( as hvac1000) correctly stated... make it their problem to correct!! ( these are my evaluations based on your posting comments on how it is running)
