hydro flame won't flame

My 1995 34' excella has a hydro flame furnace. I got the furnace to work once and never again. We just bought the rv this summer and never tried the furnace before now. The other gas appliances work just fine. The blower comes on but I do not hear any clicking of the solenoid valve or the igniter. I took the DSI board in to the dealer and they said it checked out just fine.Does anyone know where the sail switch is located on this thing? Do I need to remove the unit to get to it? What should I check out next? Is there an easy fix to this?

Thanks for any help.

Since no one out there has been able to offer me any advice on this problem I will post what I came up with. After isolating all the switches and safety systems the problem turned out to be the over heat sensor near the combustion chamber. I bypassed it and the furnace runs great. I have a new one on order.

Atwood Furnace, Hydroflame,

Thanks for posting the results. I see you have your problem solved.
If you use the search option on the top blue bar, and type in Atwood, or Hydroflame, you will get a lot of info on the furnace. The Atwoods are a very common furnace and used in many Rv's large and small.
I have also spent considerable time solving my furnace problems, that ended up being poor contact at the circuit board plug.
It is nice to have a good warm unit now that winter is approaching!
The furnace should be serviced every year. Many posts give tips on this.
