I don't have a verified resistance spec for the 640149 thermistor. Its resistance changes with temperature, so you need Norcold's chart to judge a reading. We'll send you the specs. 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.
