My Nordyne furnace is flashing 4 times what does that mean? I am missing the tag on the door that shows all codes.

From site

Gas furnace fault or error codes for common furnaces - Gray Furnaceman Furnace Troubleshoot and Repair

They both referred to a failed ignition.

Nordyne has a 2 color code red and green. What are BOTH of them doing?
