Are you sure it is even lighting. If you stand outside by the exhaust, you should be able to feel the heat if it lights. My previous rvs furnace wouldnt light, but the fan would come on and run, making it sound like the furnace was on. It turned out to be a worn out thermostat. I replaced it, and all was well. Before I replaced it, you could wiggle the heat button, and get it in just the right spot. Then the furnace would light. The button was worn out, but if you were patient, and held your tongue just right, you could find the right spot to get it to light. Replacing the T stat was much easier.
