    La Cimbali m21jr heat relay

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have a La Cimbali m21jr that won't stop boiling - I changed the pressure stat and thermostat and still no luck. I have heard it could be due to a bad heat relay. I believe that the relay on these is solid state but I am having trouble locating it...a newbie question but any help would be appreciated! here is a picture of the cimbali board.jpg

    The switched active for the element I think comes from pin 2 on the right hand terminal block, it's most likely a faulty triac.
