Re: flame sensor on a goodman heater
The flame sensor will be located either left or right of the burners and there will be only one wire leading to it. It is positioned so the flame hits it last. So if you watch your flame spread, it will be on the side last to see flame.

Hello,sounds like you have a dirty flame sensor. This is a metal rod on the oppositenside of the hot surface ignitor. turn off power to the furnace and remove the flame sensor, then use steel wool and clean the flame sensor and reinstall. Next turn back power to Furnace.
First when it goes out again, locate the furnace and look thru a small viewing port to see if there is a light blinking, count the number of blinks. Then look at the wiring diagram for a diagnostic code chart. This will give you a strart of where to look.
Heat sensor....Or a flame sensor. Flame sensor is connected to a "single" wire under the buners usually found on the left side. Heat sensors (or flame rollout switches) are found surrounding the burner box. The most common bad one will be located just above the burners. it "should" have a small reset button in the middle just between the two wires. If the furnace does light even for a short time the rollout switch is not bad.
The flame sensor is dirty. You can not see the build up on the sensor but enough build up will change the resistance and the furnace thinks there is no flame.
To clean the sensor, first you need to locate it. it will be a sensor located in the path of one of the flames. Once you locate the sensor, open the bottom panel to turn"off" the furnce. After the panel is removed, unscrew the sensor from the frame above the jets. Use a clean rag and gently wipe the sensor several times. Place back in the cut out and close the lower panel.
The furnace should cycle on and the flame stay on for the normal cycle.
