I have a newer Payne Central air unit in my house.

Long story short. It is working fine but tonight i decided to look at
it. THe little window shows a red LED. I assume the LED is for testing
as that is what is indicated on the door of the furnace. My question
is....the door sticker makes no mention of the LED if the LED is on all
the time.

Mine is on....it doesnt flash or anything...just on solid.

is this normal?

Yes, it's indicating *power on*. The board will flash out a code if it
senses a fault.
