Since I have no access from the front if I pull the furnace do I need to disconnect my outside exhaust port? Or does it just slide out?
There are a number of pretty good YouTube videos on the subject. If you don't hear the distinct 'click' of the gas valve, I would first suspect the sail switch, especially if you have pets (hair).
Any work done on the units with the small exhaust duct requires removal of the furnace from the inside. It's not too tough, except for lying on the floor for us old guys. You can usually leave the exhaust alone, but it's a little tougher lining up the duct on reinstallation.
I would go through troubleshooting first though. You don't want to take it out if you don't have to.
