If all burners DO NOT light and the flame does not touch the flame sensor and gas pressures have been confirmed as correct
  • Check flames travel freely across all burners at ignition
  • Check burner slots are aligned
  • Check cross-lighting slots on burners for obstructions - clean/clear is required
