Furnace Blows Cold

[dadseven09]

I have searched through many threads on the forum concerning a furnace blowing cold air and it has been very helpful so far. This is what my furnace did on our last camping trip of 2015 in our Wildcat 312BHX fiver.

I have checked the propane tanks - they are full and the crossover valve is working properly. I am getting a good blue flame on the stove and the water heater also works just fine. I can turn the furnace on at the thermostat, the fan comes on and then shuts down because there is no ignition of the gas. After reading the different threads, it must come down to the sail switch, gas switch or control board. If that is the case, is this something I can fix or would it be better to have the RV dealer fix? The camper is still under warranty.

Opinions welcome......

Dealer.
Unit is still under warranty why not have them fix it?

As Ford said, if it's still under warranty (They have a two year warranty) it's better to let the dealer do it. However, it is a job that you can probably do yourself if it's not under warranty for some reason or if it's a huge pain to have a dealer do it.
