    Goodman Furnace Code 8?
    Hey everyone. I installed a goodman GMH80453 the other day. On the day of install I started and ran it twice with no problems. Now it won't run. Series of events are... Turn up stat to kick it on, inducer fan comes on, runs for about 10 seconds.. Then clicks shuts down and flashes a code 8(which is not listed in manual). The ignitor never glows. I don't see any burn spots on the board and 3amp fuse on board is OK. I can flip the power off then back on and it will go through the same series. Has anyone ever had this problem? Any Ideas? Any Input would be great. Thanks!

    Did you adjust/set the correct gas pressure?

    It is all here in the instructions for your unit. NOTE you failed to give a complete model number so I just picked one of the two install manuals.
