The stove is some 20 years old and the broiler stopped working a few months back, and the oven has sitting slower to light, taking 5-10 minutes to light. We’ve been told to get new igniters, but can’t find a source.
We don’t do residential equipment here. Yet, since it’s a Garland, I did a little looking around for you.
From my little research, I found that Garland discontinued their residential line of products in 1999. However, they offer up information on parts support of those old products. Here’s Garland’s web page for information on that:
As I recall, they used a HSI igniter on the home line. And a restive valve for the burner. It has a bimetal strip that opens the valve when the current flow is right If the wattage of the igniter gets out of spec, it will delay ignition or not light.
