If the igniter is not functioning properly, you may perform a quick check to see if the rod is still sticking into the burn pot at least ¼ inch and you should feel warm air blowing when the unit is on. The rod gets hot ½ inch back from the tip, if the rod has been pushed too far back into the tube it will not ignite the pellets. The rod will only push back if the set screw is not tight enough. Please find attached the installation instructions for changing your igniter, you can use these as a guideline to check or reposition your igniter rod.
You will also want to check the wire connection behind the control board. Each wire has a pin on the end that must click into the molex connector to provide a complete connection. If one of the wires in your unit was just pushed up against the connector and did not clicked in, it could have pulled away and broken the connection. You can remove the screws that hold in the control board OR remove the bottom panel of the hopper to access the wiring. The igniter wiring is purple/white on one side and white/white on the other. If you gently pull on the wires at this connector, one of them may be loose. Push each wire tightly into the molex plug and reconnecting the plugs to confirm a tight connection is achieved.
Remove Cooking Grids and Flavor/Grease Tray. Turn unit on and visually inspect the igniter.
