Denon 3803 issue, no sound in sub? Help

I boutght a new sub last week and hooked it up to my Denon 3803 and I am getting no sound out of it, I then put the old one back in and the same thing no sound. I checked the cable and both subs seem fine so I think it is the receiver. The sub is turned on in the configuration and I am testing it by using the balance channel level screen I go to all the speakers and they all have sound except the sub. Any other idears or is the receiver dead?

Is there a way to factory reset this receiver?
