The Norcold 50806 is the OEM replacement exterior refrigerator vent assembly for Norcold 2118 Series RV refrigerators — the sidewall panel that covers the refrigerator's exterior ventilation opening and provides both the upper exhaust and lower intake airflow paths in a single combined unit. Previously known as Norcold part number 637318BK, this is the same direct-fit assembly under an updated part number.
Norcold absorption refrigerators require continuous exterior ventilation to exhaust heat from the cooling unit and draw in ambient air. Without proper vent function, the refrigerator can't maintain temperature and may shut down on high-temperature lockout. This vent assembly replaces cracked, faded, broken, or missing vent covers with a factory-matched black plastic unit featuring radius corners to match the 2118's exterior styling. Made in USA.

Norcold absorption refrigerators generate significant heat at the back of the cooling unit during operation. This heat must exhaust freely through the upper vent opening while fresh ambient air is drawn in through the lower intake. When vent openings are blocked, cracked, or missing: • Cooling performance degrades — refrigerator runs warmer than set point • High-temperature lockout can shut the refrigerator down automatically • Prolonged heat buildup accelerates cooling unit wear A damaged or missing vent cover is a repair worth prioritizing — it directly affects refrigerator performance and longevity.
