My furnace does not seem to be blowing air. At first I thought it was access panel switch due to a bent panel. However, I held it down while someone else stayed by a register to check airflow and there was very little if none. Also, the gas never lit, but I could smell some.

Thoughts?

What type of furnace do you have? Do you have air conditioning? Or a fan on switch at the t stat?

Payne natural gas furnace.

No A/C.

I can set my thermostat to "fan" or "auto". There is no airflow under either option. Even when I hold down the cover switch and the furnace activates, there is still no airflow.

OK how new is your furnace?

Has the fan ran on the on position before? Or only on auto?

Sounds like the blower motor its self or the control board

Are the blower motor or control board easy to replace?

Yes, but you need to see if the power is coming out of the board or not to the moter

Sounds easy enough. How do I determine this?

If I can figure out where the power flow stops, then is that the piece that needs replacing?

Try this, shut power off to furnace, or just don't hold in the door switch. Now reach in and try to turn the blower wheel by hand. Does it spin freely, or is it stiff? If it spins freely, then push in the door switch(with power on, make sure not to touch any wires, or capacitors with your hand or arm). With door swith engaged, and thermostat set to fan on. Give the blower wheel a push by hand, try both directions, if it tries to start turning but won't get up to speed, I would suggest that you have a bad motor. If it takes off and runs fine when you give it a push, you may have a bad capacitor. This is real easy for someone that works with these type of things on a daily basis, but I really would recommend having a local tech in to look at it if you don't feel comfortable.
