When my Goodman furnace (CWP#00299785) turns on, the blower works and the burners ignite, but after a few seconds the burners extinguish. Then the burners ignite again for a few seconds and extinguish once again. Please tell me what part(s) I need and where those parts are located on the furnace.

Thank you!

On the inside left hand side there will be looks likes a 8 penny nail, take a sos pad and clean it,the oxgen sensor is dirty, should fix it.

Sorry not the oxgen,it's the flame sensor.

Mine was doing the same thing and this worked for me. It looks kind of like a needle located in front of the last burner on the left! This is why I love Google! Saved me some money
