This Kenmore gas range has lost all gas pressure to the burners due to the propane tank that was hooked up to it being damaged - new propane tank currently hooked up however no gas pressure at all to burners - i suspect the pressure regulator needs replaced as i attempted to light the burners manually with lighter but no luck. Does this sound like a logical part to replace in this situation? if so, does anyone have a diagram that would show where i need to go in the range to replace the regulator and what tools i might need? any help would be greatly appreciated
