I bought a used Maytag MGR5745ADA gas range that was converted to LP. The manual provided instructions on how to set the over back to Natural Gas. The stove top burners now work fine. The issue now is that when i turn on the oven or broiler I hear a high pitch hiss and the over doesn't light. I assume I would need to adjust the orifice for the oven and broiler burners also, but nothing i found in the manuals or online talk specifically about the oven/broiler burners.
