How to fix a Vermont Castings VM400 burner that will not light?
- MMark ScottJul 26, 2025
If the burner on your Vermont Castings Grill won't light, several factors could be at play. First, ensure the gas supply is turned on and that you have propane. Check for any blockages in the gas system or misalignment of the gas valve to the burner's venturi tubes. Also, verify the propane hose and regulator are correctly attached. To resolve this, turn on the fuel supply and try again, confirming gas flow by smell or sound. Weigh the propane cylinder to check its fullness. Clean any blockages in the venturi tubes with a venturi brush and carefully probe the gas valve orifice with a pin or needle, without enlarging it. Reinsert the gas injector into the venturi tube if needed, and tighten the regulator's plastic collar onto the cylinder valve by hand.
