I bought this to replace the carbide igniter in my Intertherm M1MB series oven. I had a "weak flame" reading when the flame was clearly not weak. I replaced the igniter a few years ago when the old one broke. This one is the same size and fits in the same position, but I had to drill a new hole and use a nut and bolt to put it in the correct position as the holes on the bracket didn't line up with the hole on the bracket . flame assembly. Also, I didn't use flimsy nuts, I soldered the wires to the existing connector and put them in heat shrink tubing. My main gripe with this part is that it doesn't come with the correct connector, but for the price I can't complain. After installation it worked perfectly.
