Goodman Furnace LED Fault Light


Hi - My Goodman furnace would not start the other day. I could here it trying, then after taking the panel off saw the LED flashing 8 times which meant a polarity issue. So I pulled the transformer, cleaned contacts, etc... tested voltage then it fired right up.

However, now its shut down again with a single flash which means the flame detector is faulty. So I cleaned it up, but now the damn light won't reset!

The code says that the system is on lockdown and that it will retry in 1 hour. Or you can turn off the power, etc.. to reset it. I've tried everything, I can't get it to turn back on.

Any ideas?
