There are several possible issues. Some easily fixed, Some not so easliy.

This is what shoudl happen.

T-Stat calls for heat
Blower starts
Sail switch (You do not see this) closes
Propane valve opens an dif it is a DSI unit sparks are generated (you can hear them if you are outside near the furnace, SNAP SNAP SNAP).
Flame on
Flame sensor gets hot and signals control board I"M WORKING.
Flame continues
Warm air ensues.
T-Stat says "ENough already"
Flame off (Solenoid closed)
Pause then blower off

Tell us where it's failling and we can help you better.

Home is where I park it!

When my suburban heater started acting up, the blower would come on, but I got no flame, thus no heat. I called my mobile RV tech, and he showed me that the connector on the circuit board at the heater unit was NOT making good contact. He cleaned it, and then it worked. I put some die-electric grease on the connector.

This question is like going to your doctor and telling him you "don't feel good" and expecting him to cure you. No where near enough information to provide anything meaningful or useful to the OP.

Really? I fixed a lawn mower over the phone... just by listening to it as GF tried to start it.

If Dunner (RVM23) can't fix it, it ain't broke!
