Looking to buy a Trane Limit. Part #SWT03108

It seems Trane no longer makes the water temperature limit for my boiler. I'm having a hard time finding one online or locally. Any help tracking one down would be greatly appreciated. It's part number is SWT03108 Thank you!

    Don't know about Trane parts but it can probably be replaced with something that is available readily.

    Post a picture.

    Trane boiler parts are probably made by someone else anyhow

    This appears to be available from the manufacturer through the distributor/dealer network. You may be able to purchase it online by using the part number in a google search.

    I can not get any more of a description from the Manufacturer ordering website, This may have a generic replacement that is available at a lower cost. If you can post a picture of the part that would be helpful. With the cover off or where the wires connect to the control if possible.
