   Michael,
Have you looked at the trouble shooting guide in coach assist? Have you changed the hidden fuel filter behind the compartment back wall? Do you hear the fuel pump clicking when you first turn it on? Fred

Micheal
The yellow / orange flame is caused by incomplete combustion either too much fuel poor atomization ( bad nozzle) or lack of air to the burner.
Your description of the fault sounds like a lack of air for combustion creating a lazy yellow/ orange flame witch does not create enough light for the flame sensor to recognize causing a system shut down.
The Hurricane units use a compressor to provide the air for the combustion chamber that compressor has a small inline air filter which could be partially plugged causing your problem.
Check the compressor for operation if memory serves me right  I believe the out out pressure on that compressor would be 10 to 12 psi .
You will likely have to clean the flame sensor as well because the orange flame creates a lot of soot
While you have the burner apart check the nozzle spray pattern it should be a nice fine mist in a cone shaped pattern.

There is a manual in the Coach assist section of the forum that can help you through trouble shooting.

Hope this helps
Eric

no have not checked the fuel filter , i did not see one at the heater so i added an inline one. u say there is a hidden filter??
that maybe the issue it seems the fuel supply not adequate.

eric , i think cleaning the photo eye would be needed as it was sooted up ! the compressor is operating but not sure of the pressure its providing ! i believe i may be starving the burner , i need to locate the factory filter as my next move 
thanks   for the info

    Michael,
As I stated earlier, you have to crawl under the compartment and then look up at the backside of the compartment to see the inline filter. Fred
