American Standard Freedom 90 problem

MichaelC

I have an American Standard Freedom 90 furnace, the ignitor, seems to not always work, and now stopped al-together. I bought a new ignitor and replaced it, but still it doesn't glow to start a flame. The Blower recycles every 5 miniuts. What other problem may I be facing? Theres no flash codes. Thanks

Is the inducer motor running,pressure switch closing?

Is there water trap in the draft motor?

how

A real call for heat that doesn't result in ignition should result in a led diagnostic code. If it doesn't, it ususally means that there hasn't been a real call for heat (Thermostat or thermostat wiring problem) or its a board problem.
Telling us if the inducer motor is running when the igniter isn't working helps point out which is which.

I have prophane gas coming in, but the igniter doesn,t light up.

well, since there is NO code flashing.....i am thinking its a bad board, if it was any other component I am almost positive it would be flashing a code.

Is the inducer motor the blower that vents to the outside? And what do you mean about water trap in the draft motor? Thanks

how

Is the led light lit but just not blinking or is it off? I do run into boards with a dead led light which throws a wrench into on line diagnostics.

Yes the inducer motor vents the flue gas out through the pipe

If drain is plug it will cause water to back up into the draft motor. There is a tan 90 vinyl elbow on that goes from draft motor then into clear tubing. If that elbow plugs up it will back up water.

Often times the flash code can be hard to see through the window. A better way to check it would be to remove the blower door and tape the door switch so that the control still has power. Next verify that there is no flash code.
