What to do if rear and side burners will not light with igniter on Napoleon Grill?
- S
  Stacy CaldwellAug 15, 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 battery or one installed incorrectly, a loose electrode wire or switch terminal wires, or lifting flames on the burner. To resolve this: * 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. * Check that the lead wires from the module to the ignition switch (if equipped) are firmly pushed onto their respective terminals. * Close the air shutter slightly.

  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 does my Napoleon LEGEND LD4 Grill have excessive flare-ups and uneven heat?

  Jorge BarnesAug 21, 2025
  Excessive flare-ups and uneven heat on your Napoleon Grill can be caused by sear plates installed incorrectly, improper preheating, or excessive grease and ash build-up on the sear plates and in the drip pan. To resolve this: * Ensure sear plates are installed with the holes towards the front and the slots on the bottom. * Preheat the grill with both main burners on high for 10 to 15 minutes. * Clean the sear plates and drip pan regularly. Do not line the pan with aluminum foil.

What to do if Napoleon LEGEND LD4 Grill burner output on 'high' is too low?
- R
  Ricky CoffeyAug 25, 2025
  If the burner output on 'high' setting is too low, accompanied by a rumbling noise and flute ring blue flame at the burner surface, it may be due to: * Lack of gas. * Pinched supply hose. * Dirty or clogged orifice. * Spider webs or other matter in the venturi tube. * Propane regulator in 'low flow' state. To address this: 1. Check the gas level in the propane cylinder. 2. Reposition the supply hose if necessary. 3. Clean the burner orifice and venturi tube. 4. Ensure the lighting procedure is followed carefully: All gas grill valves must be in the off position when the tank valve is turned on. Turn the tank on slowly to allow pressure to equalize.

Why is heat low / flame low when valve turned to high on my Napoleon LEGEND LD4 Grill?
- T
  Taylor PerezAug 30, 2025
  Low heat or flame on your Napoleon Grill, even when the valve is turned to high, can be caused by: * Improper lighting procedure (for propane). * Undersized supply line (for natural gas). * Improper preheating (for both gases). To fix this: * Ensure the lighting procedure is followed carefully. All gas grill valves must be in the off position when the tank valve is turned on. Turn the tank on slowly to allow pressure to equalize. * Ensure the pipe is sized according to the installation code. * Preheat the grill with both main burners on high for 10 to 15 minutes.

  If the burners on your Napoleon Grill burn with a yellow flame and you smell gas, it could be due to a spider web or other debris, or improper air shutter adjustment. Thoroughly clean the burner by removing it. Open the air shutter slightly according to combustion air adjustment instructions. (This must be done by a qualified gas installer.)

Why does 'paint' appear to be peeling inside lid or hood of my Napoleon Grill?
- S
  starkseanSep 8, 2025
  If 'paint' appears to be peeling inside the lid or hood of your Napoleon Grill, this is not a defect. The finish on the lid and hood is porcelain and will not peel. The peeling is caused by hardened grease, which dries into paint-like shards that flake off. Regular cleaning will prevent this.
