Thanks for the question.
I've tracked down the replacement thermostat for the Turbo Air TCBE 52SDR Refrigerator Chef Base that you're searching for. You'll want the Turbo Air K55-Q5608 Thermostat, and while we don't currently stock this particular part we're always happy to special order pieces for our customers. That said, if you also need to replace the thermostat cover you'll want part # STS304-2B.
Please give a member of our Tundra Restaurant Supply team a call at 1-888-388-6372 and we'll get you the parts you need.
