First, how old is the 1207? If it's old enough, it won't have electronic ignition, but that's doubtful.
Next question - did you give it a little while of running? It won't blow warm air immediately. But if you didn't hear the ignitor trying to light, then yeah, there might be some kind of issue there.

I had a 1997 Jayco 1207. You can't light it manually. Mine was temperamental it would not light unless both tanks were open. It would not run if the hot water heater was heating. We did take it to the shop and they replaced a thermocoupler, but that did not help either.

the pop up is a 1996. We didn't hear the ignitor sparking to light, so I guess it needs to go to the shop and have them look at it. Thanks to all who responded I appreciate your help.
My 2005 Jayco 1006 has a auto igniter on the furnace. It will not light unless there is enough power in the battery to light it. Apparently it takes quite a bit of power as the fan will run, lights light, ect. On mine it was a pourly charged bad battery that did not let it light. With a new battery it lights just fine.......Shredder
Scott, I had not thought of a poorly charged battery causing the problem. Thanks for that tip.
