I installed a new goodman 2-stage furnace in my garage and
converted gas valve to propane as per instructions, and when
I turned on for the first time the burners came on but when
blower motor came on the burners shut down and the l.e.d.
light was blinking 8 times. The troubleshooting chart only
goes to 7 times or continuos.What could be the problem?

8 FLASHES=Problem with igniter circuit. Improperly connected igniter or Bad igniter or Poor unit ground. Check and correct wiring from integrated control module to igniter. Replace bad igniter, Check and correct unit ground wiring.Turn power OFF prior to repair.Replace igniter with proper silicon nitride replacement part.
Right out of the GMV95 service manual.

Same code in the GMV as the GMH in the Goodman service manual
