so its 90 degrees outside. My AC unit outside will kick on with the AC fan working. Inside the house the furnace fan will not kick on to circulate the cold air in the house. the AC line leading into the furnace will actually freeze up due to compressor running and no where for it to go. If you go downstairs and just give the lower furnace door a nice tap the fan will kick on. I can not figure it out. I have tested the door switch which shuts furnace off when door is not on. I have unplugged almost all connections on the board to make sure they are clean and getting good contact. I am pretty mechanically inclined but this has me stumped. Sometimes the system works just fine and other times it will not. In the last 2 days we have had to hit the door 5 times to kick it on. Is there a solenoid somewhere that I am not seeing going bad? Is the motor itself going bad and intermittently needing a small bump to get started? Also the furnace looks to be from 2007 and is a york furnace. Any help would be greatly appreciated! thanks in advance.
