Used Norcold Refrigerator Gas Valve Burner Tube Combo - 637540 , 638982

Overview & Function

This pre-owned Norcold offering combines a refrigerator gas valve with a burner tube under numbers 637540 and 638982. The assembly supports gas-fueled refrigerator operation where flame heating is specified. Used status is disclosed prominently because fuel-gas components demand careful inspection and qualified handling. ### Fitment & Compatibility Fitment is limited to Norcold refrigerator applications specifying the 637540 gas valve with 638982 burner tube combination. Buyers must cross-check model and serial data before selecting pre-owned gas parts. Exact Part Supply flags this as a qualified-personnel item rather than routine DIY replacement stock. ### Technical Construction & Specifications Confirmed details are Norcold brand, part 637540, companion number 638982, gas valve plus burner tube combo, refrigerator application, and used pre-owned condition. No additional pressures, orifice sizes, or dimensions are stated beyond these facts. The listing covers the valve and tube combination only. ### Installation & Maintenance Guidelines Gas work must be performed by qualified personnel with leak testing, combustion verification, and vent inspection. Do not reuse damaged seals or compromised fittings. After installation, verify ignition, flame stability, and refrigerator cycling, and maintain annual gas system inspections for continued safe operation.
