Serial Number on Goodman furnace?

[iggy123]

Where can I find the serial number on my Goodman furnace? The air condenser # was easy to find but not for the furnace. I didn't want to open the access panel because the furnace is powered and the fan is running. I can't find the warranty paper. Help please!

The upper access panel can be opened without the fan shutting off, that's where hte burners are and the serial number and namplate info is there. HTe blwoer compartment is a seperate panel.

However, usually the serial number is also located on the outside of the unit on one side. It is on Carriers. But maybe not on Goodmans.
