Yesterday, we found the furnace not to be working. The blower comes on and stays on. The draft inducer runs for a few seconds, but then shuts off. There is no heat, and I smell no gas. The gas meter doesn't appear to budge.

This is a Trane YCC048... from around 1996 (I don't know the exact model, but I could run out and open the panel again if it is important). The diagnostic LED flashes a code of 6, but I have found no reference for what the codes mean on this particular unit, and the booklet doesn't mention codes. It is just installation instructions

The draft inducer pressure switch is functioning normally, and the rollout switch is fine (a test showed that there would be a diagnostic code of 4 if it were open).

is there a detonationin side the pannel?/ Oh well I ll say off the top of my head the induction blower is fubar the fins of the wheel are not there any more and the pressure switch is not making tus the unit stops its attemt to light. Other causes are no ignition flame sensed thus shut down. call a pro of youll lose your eyebrows when it lights in your face.

Be good to your fellow man not nice there is a difference.
