Why won't my Napoleon PRO500-3 rear and side burners light with the igniter?

  Robert MillerAug 22, 2025
  If the rear and side burners on your Napoleon Grill will not light with the igniter but will light with a match, it could be due to a dead or incorrectly installed battery, a loose electrode wire or switch terminal wires, or lifting flames on the burner. Replace the battery with a premium heavy-duty battery. Check that the electrode wire is firmly pushed onto the terminal on the back of the igniter and that the lead wires from the module to the ignition switch (if equipped) are firmly pushed onto their respective terminals. Slightly close the air shutter.

  If the main burner on your Napoleon Grill will not light with the igniter but will light with a match, the jet-fire outlet may be dirty or clogged. Clean the jet-fire outlet with a soft bristle brush.

Why do my Napoleon Grill burners have a yellow flame and smell of gas?

  A yellow flame and the smell of gas from your Napoleon Grill burners could be due to a spider web or other debris, or an improper air shutter adjustment. Thoroughly clean the burner by removing it. Open the air shutter slightly according to the combustion air adjustment instructions. Note: This adjustment must be done by a qualified gas installer.

What to do if my Napoleon Grill burner output is too low on the 'high' setting?
- K
  Kayla CruzSep 13, 2025
  If your Napoleon Grill's burner output is too low on the 'high' setting, with a rumbling noise and fluttering blue flame, it could be due to several factors: lack of gas, a pinched supply hose, a dirty or clogged orifice, spider webs or other material in the venturi tube, or the propane regulator being in a 'low flow' state. Check the gas level in the propane cylinder and reposition the supply hose if necessary. Clean the burner orifice and venturi tube. Ensure the lighting procedure is followed carefully: all gas grill valves must be in the off position when the tank valve is turned on, and turn the tank on slowly to allow pressure to equalize.

How to fix low heat or low flame on my Napoleon PRO500-3 Grill when the valve is on high?
- M
  Michael PetersonSep 12, 2025
  The issue of low heat or low flame on your Napoleon Grill might arise from a few reasons. For propane grills, it could be due to an incorrect lighting procedure. For natural gas grills, the supply line might be undersized. For both types, improper preheating could be the cause. Ensure you follow the lighting procedure carefully, keeping all gas grill valves in the off position when turning on the tank valve. Turn the tank on slowly to allow pressure to equalize. The pipe must be sized according to the installation code. Preheat the grill with both main burners on high for 10 to 15 minutes.

Why doesn't the side/rear burner ignition work on my Napoleon PRO500-3?
- A
  April ReynoldsSep 7, 2025
  If the illumination of the knob and switch lights work fine, but the side/rear burner ignition does not work on your Napoleon Grill, the ignitor switch or the ignitor block may not be working properly. Replace the ignitor switch if the switch light illuminates when you turn the light switch on. Check the switch connection inside the control panel. If there’s no light on the switch when you turn it on, replace the ignitor block if the switch illuminates and sparking noise can be heard.

  If the ignitor, oven, and cabinet lights on your Napoleon Grill work, but the knob lights don’t illuminate when turning the power switch ON, the motion sensor detector or the wire harness may not be working properly. Ensure the blue indicator is ON. Turn the sensor ON by clicking the motion detector button. If the blue indicator is ON, replace the motion sensor. Replace the wire harness of the control panel.

Why are the flames lifting away from the burner on my Napoleon PRO500-3 Grill?
- C
  Craig LivingstonSep 4, 2025
  If flames lift away from the burner of your Napoleon Grill, accompanied by the smell of gas, and possibly difficulties in lighting, it may be due to improper air shutter adjustment. Close the air shutter slightly according to combustion air adjustment instructions. (This must be done by a qualified gas installer.)
