Do you hear the gas fire up in the unit? If not the gas valve may not be opening to allow the burner to come on and fire up.

yes the gas comeon and it lites but it keeps going on and off

Could be loose connections at the controls or gas valve, or could be sail switch not proving in a solid fashion(providing you have a sail switch as some do). Located in the air supply of the heater.

I had problem that my heater wouldn't come on last week. Blower would work just fine but no heat. I thought it was the sail switch but I still had no heat. Out comes the mobile RV repair guy and after 30 minutes he narrowed it down to the problem. The orfice was clogged with......knats....little biddy knats. You could barely seen them and when the repair guy says "watch what comes out when I take the orfice off". I have never had this problem nor have I heard of anyone else having this problem.
Food for thought.

Allen,
I had a similar problem awhile back. Seems I tore a small hole in the flexible ducting in the basement area. I repaired the damage and everything worked as advertised after that. It's worth a look. Mine was caused by the corner of a tool box and was hard to see the damage. Turn on the heater and run your hand all around the ducting and then it's easy to find if that's your problem. Good luck,
John
