The gas valve was not turning on.

 The furnace would try to start and the ignitor would glow red. The gas valve never came on. The circuit board was ok and flashing a 3 light signal. the board says this is a pressure switch or limit. The switch works but it had no signal. The tube was clogged going into the draft motor. Resolved another one without having to replace parts. This was a tuff one for beginners but not me,.
