Question about Goodman GMS90703BXA Heater
I cant be sure but usually the constant blink on some boards means reversed polarity. Check your HOT (L1 - Black) comming in to the connector box and the your NUTURAL (L3 - White) should not read any volts to ground (not more than 12 volts on an electronic VOM). If this is opposite remove power and reverse black and white wires and retry.
HOPE THIS HELPS PLEASE GRADE ME ACCORDINGLY and GOOD LUCK!
