Description
The Norcold 50665 thermistor and lamp-wire assembly is listed for 1200-series RV refrigerators. It combines the refrigerator's temperature-sensing lead with an integrated wiring harness; this is not the separate high-temperature safety recall device.
Part Identification
- Supplier part: 50665
- Supplier cross-reference: Norcold 621742
- Application: Selected Norcold 1200-series refrigerators
- With Wiring Harness: Yes
- Function: Thermistor/lamp wiring assembly associated with the fresh-food interior light bracket
Serial-Number and Connector Check
Norcold's 1200-series parts list separates earlier 621742 thermistor/lamp wire kits from later 636658 assemblies near refrigerator serial 849677. These are not automatically interchangeable merely because both serve the 1200 family. Check the complete refrigerator serial number, connector arrangement and original part marking before ordering this supplier-listed 50665 item.
Repair Notes
A thermistor measures refrigerator temperature for the electronic control system. It should not be confused with a high-temperature safety/recall component. Diagnosis is recommended before replacement; limited supplier warranty as originally listed.
