Light diffuser assy, freezer
Get your Sub Zero 642 back to even, reliable cooling with genuine OEM replacement parts from Repair Clinic. The Model 642 is a built-in side-by-side refrigerator and freezer from Sub Zero’s 600 series, designed to sit flush with cabinetry and serviced from the front. Parts replaced most often include the 642 evaporator fan motor, the door gasket, the ice maker, and the water inlet valve. Find your part on the 642 parts list, then browse all Sub Zero refrigerator parts.
In a side-by-side 642 refrigerator, freezer and fresh food sections run the full cabinet height, so temperature problems usually show up on one side first. Isolate that compartment before any compressor diagnosis, and check its fan, defrost parts, and door seal. The condenser sits behind the top grille, where dust raises compressor temperature. Fans, valves, and ice maker parts are shared with other 600 series side-by-sides such as the Sub Zero 632, while panels and trim vary by finish suffix, so confirm against this model’s list. The 642 manual and 642 diagram show part positions. For 642 repair steps, open the model troubleshooting page.
When the fan stops, cold air stays at the coil and the compartment warms while the compressor runs. No fan sound during a cooling cycle confirms the motor has failed. Replace the fan motor for that side.
The 642 door gasket wears first at the bottom corners of each tall door. If a strip of paper slides out with no drag, the seal is letting humid air in. Order a new gasket.
Confirm the water supply is on and the freezer is cold before replacing the 642 ice maker. If water reaches it and it still will not cycle, replace the ice maker.
The 642 water inlet valve feeds the ice maker. Test its solenoid for continuity and check the inlet screen; a failed valve stops water while the ice maker is fine. Shop valves here.
Isolate the warm side, then check its evaporator fan, defrost system, and door gasket, and clean the condenser behind the top grille before suspecting the compressor.
Check the water supply, freezer temperature, and inlet valve solenoid first. A failed valve is a common cause and costs less than the ice maker.
Close each door on a strip of paper at several points. Any spot where the paper slides out freely means the gasket should be replaced.
Many mechanical parts are shared across 600 series side-by-sides, but panels and some components differ. Confirm against this model’s parts list.
