Bedroom furnace clicking, but not igniting.

[JeffAndPam]

Our RV comes with two furnaces. One works fine (in the Kitchen area).

The Bedroom furnace tries to light. I hear it clicking several times, but never lights.
After attempting to light, it stops clicking and an LED flashes 3 times. The label for that reads "Ignition Lockout Fault"

I can only think of two things: 1) a spark is not actually being generated (although I can't see where that device is). 2) there is no gas flow.
What's the best way to determine these? Or could there be another issue?

It looks like this is a new unit. Here's a picture:

NOTE: After not getting replies for a few days, I decided to repost my question under Heating, Cooling, Plumbing, to get a wider audience (and since this question isn't specific to my RV type).

I would have deleted this post, but it doesn't look like I can.
If an admin sees this, feel free to delete this thread.

I would begin by checking the vent system and the sail switch. The lock out message would seem to indicate something with gas flow or blocked exhaust. This could also be a bad gas valve.

Question - Are you smelling gas? Seems like if there was gas but not igniting, you would smell that.

And seem to be getting some responses there. So I'd like to keep the thread alive.
PLEASE POST ON THAT THREAD.

In fact, can an admin close down this thread?
BTW, @Jirah, I tried but couldn't tell very well. See that other thread for more details.
