After moving a 20 year old GE XL44 stove, we began to notice a faint propane smell from the oven. After dabbing soapy water over every connection, we could see it was coming out of the broiler nozzle. Using the AppliancePartsPro web site, we could quickly identify the valve part we needed.
We assumed we would be without our stove (gas off for safety) for at least a week, but almost miraculously, it arrived the next day! A few simple tools in a hard to reach place and the repair was complete. Tip: take lots of pictures of it before you remove it so that you can put the wires back on correctly.
