It’s a solid state relay and 9 times out of 10 when it’s a shorted up to speed problem what’s actually failed is the little surface mound protection cap across the contact. Once I noticed that new boards from Siemens were coming out without that cap installed I started just pulling them off instead of replacing the logic board. It's C65 directly under the SSR, usually under a lot of hot glue but if you cut a square around in with a knife and pull it out the cap typically comes with it.
