Lennox G40DF, no power?

It is a 10 yr old smaller furnace that heats the upstairs, it has worked fine with no issues. Now there is no power, no flashing lights, fan, total zero.

I looked at the one fuse I can see it looks fine, I have turned the breaker on and off, flipped the power switch, touched it with an electrical tester and that showed that there is power going to it according to my neighbor.
I see nothing visibly wrong with it.

Any idea what the problem may be?
