Unhappy Goodman GMP075-3

I have a GMP075-3 Goodman furnace and it has an issue, it ignites but the flame immediately goes out it doesn't burn longer than maybe 2 seconds. Everything else seems to be in working condition.

Clean the flame sensor. It's a metal rod with a wire attached to one end. If your igniter is near the left burner, the flame sensor rod sticks up in front of the right burner. Remove it (usually two screws) and clean it by wiping it lengthwise with fine emery cloth, sand paper, steel wool, or even an SOS pad. Wipe it to clean it - not to remove metal. Reinstall and hopefully have a warm house.

By the way, welcome to the forums.
