Everything for the Norcold NX611, NX641 & NXA641

Fits every Norcold NX641 and NXA641 model: NX641, NX641IM, NX641.3, NXA641, NXA641L, NXA641R, NXA641IM, NXA641IMR, NXA641.3, NXA641.3R. NX611 owners: Norcold's NX parts list doesn't cover the NX611, so check the model list on each part. (L / R = left or right door hinge, IM = ice maker, .3 = 3-way.) Norcold uses other suffixes too (C = cold weather, SS / BK / WH = wrapped doors, F / V = fan), so if yours has extra letters, it is still in this family. 6 cu. ft. two-door absorption fridges with front-panel button controls. Cooling, propane and power board parts are shared. The front display board is not.

Display dark or buttons not working? On the NX611, the 638996 front board is still available. On the NX641 and NXA641, Norcold has discontinued the front board (638997). Before you decide anything, run the checks in our optical board guide. A dark display is often a power or fuse problem, and sticky buttons can be just the 635624 button retainer. If the board has truly failed, the Norcold N7XF keeps propane and electric, or go 12V compressor with the Norcold N8DC. Send us your model and we’ll confirm the fit for your opening.
