My start button is not working on old machine I just bought. There is a button with code AV322461 that has a clicker on top with a red button and 3 connections where I believe wires would go. I tried to upload a pick. This is about 1 inch big with a black button on metal backing where two screws may go.

i tied to upload pics here but it won’t let me. How can I get pics to you to get help?

any help appreciated
