So having said that free of charge the answer information, is as follows. Your air handler / furnace is a 90% efficient unit . The exhaust out let or pipe if you will , is PVC piping is ran horizontal depending on location of Installation and if it is Installed so the pipe is not sloping to the out side or has a dip in the middle, the condensation/ moister will plug or shut off air flow and cause the OCM/operational - control -module or computer board to not close any switch's /or let it run . That is so if the pipe is blocked the exhaust won't back up back in to your house. On all newer unit's are equipped with Diagnostic computer board's .The information you need to access the diagnostic system and the code's that indicates the problem is found ether on the inside of the fan access panel , where you should also find the OCM/diagnostic computer board, or at your HVAC dealer or part's store. My bet , the exhaust is full of water!
Good Luck
