Heater not lighting

[maintsuper7]

Hey folks, as I sit here on a Sat night I am going through my head as to what I need to do in the spring. One question, when I went to fire the heater last fall, it did not light.I heard the clicking, which I believe is the starter like the gas grill but no fire. Nothing obvious. Have gas through out the other appliances...any thoughts as to what to look for.

If you are getting a spark but no light, you have a gas supply problem (I guess that is obvious). I am curious if the coach had been in storage and/ or the furnace had not been used for some time. If so, I would take a look at the gas valve as a potential culprit. Over time, the diaphragm inside the valve dries out. Sometimes it leak and often it just shuts down. There is also potential for small bugs getting into the gas line, clogging the orifice.I would be very surprised if it was electronic. Even though the gas is controlled by the board, it's sending a spark which is a positive sign. Good luck!
