Blower turns on then off when A/C and Heat are both off.
 
I have the ComfortMaker N8MPN

the AC is off
the heat is off
the fan is set to Auto

the blower cycles on for 5 seconds or so then cycles off and the blink codes come out at 5.

Blink code 5 says: Flame sense out of sequence.

I have my ideas of what is wrong but I'm looking for feedback on what the problem might be.

Gas Furnace

the unit is about 4 years old.
