Furnace Won't Start, Cent. Air is Working

Hello all and thanks in advance. My furnace is a Rheem Critron ll. It will not come on. It makes no noise like it is even trying to come on. It is not getting the signal to turn on. I have central air as well and it is controlled by the same temperature control and it is working fine. Any suggestions would be appreciated.

pull the stat and jump R to W on the subbase with a paper clip 24Vs no swet...nothing?go down to the furnace and jump the same R to W on the terminal strip in the furnace...nothing,do you have a flue damper with an end switch possibly.if you jump in the furnace there is something on the heating circuit solid state board with lights on it (getting 24Vs) maybe..you should get at least a spark (with the r-W jump) looking to ignite the pilot to start the sequence.
