No flame signal? Replaced flame sensor but no joy

[motoguy128]

Ha this is the best reply in the bunch. I am a new tech and spent 17000 to get my diploma and gas and oil 2 tickets, so call a trained service tech.

That's nice... I dropped $60k+ on a 4 year degree. Until you get field experience and learn good real world troubleshooting and get familiar with each make & model of equipment... it's just a nice piece of paper to get your foot in the door. BTW - my degree is completely unrelated to HVAC or facilities engineering, but it was still a good investment. I learned something and it got my foot in the door.

Some of the best techs on this board probably don't have formal schooling, but plenty of certifications and tons of experience that makes them some of the best in their field.

Hi, I have a Goodman Furnance #GDS80703ANA, and the led flashes 7 times, saying that there is no flame signal. When I turn it on, the blower starts, the ignitor glows, but it doesn't start burning, there is no flame at all. I've replace the flame sensor, but still nothing. Please let me know what you think! Thank you!

You didn't mention if you heard the gas valve open, or checked to see if it was getting power. If the pressure switch had failed, I don't think it would even light the ignitor. Most equipment manuals have a sequence of operations or a flow chart.

The board may think that it's opened the gas valve, since it' throwing a no-flame fault. Menaing it thinks there should be a flame. IF it was a pressure switch, it woudl throw a code for pressure switch, thinking that the inducer had failed or there was low draft (obstruction).

See... you just have to think like a furnace. Its' easier ot troubleshoot a furnace for this reason, than troubleshoot a woman. A guy can think like a furnace... but sure as he** can't think like a woman. A furnace uses rational pre-programmed logic. A woman... well....

There maybe an "on /off" switch on top of the gas valve. Is it on?

keep throwing parts at it; even a blind squirrel gets a nut once in awhile.
