I completely understand your passion for saving a family heirloom! My grandmother's 1960s O'Keefe & Merritt stove is my own treasure, and when the oven thermostat failed, I faced the same "just replace it" chorus. It was so discouraging until I found the team at https://highcityappliance.com/ . They have a real appreciation for these classic machines. Their technician sourced a refurbished part and got the old girl humming perfectly again, all while sharing stories about working on similar vintage units. They truly get it. Don't give up hope; there are still craftsmen out there who value preserving history. I'd definitely recommend reaching out to them to see if they can help save your Coldspot.
