The Norcold Thermocouple 618445 has been discontinued by Norcold, and we don't have a confirmed alternate that fits the 323T. The Norcold 323T itself is discontinued as well. Norcold doesn't offer a direct propane replacement in that size. The closest size in their current lineup is the Norcold DC740 (12V DC compressor), which runs on DC only instead of propane. See our Norcold replacement guide for the full list.
Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you. You can also browse www.rvfridgeguys.com.
