Diagnosing a Side-by-Side 632 Refrigerator
In a side-by-side 632 refrigerator, the freezer and fresh food sections run down the full height of the cabinet, so temperature complaints usually affect one side first. Isolate the compartment before any compressor diagnosis: if only one side is warm, start with that side’s evaporator fan, defrost components, and door seal. The condenser is behind the top grille, where dust buildup raises compressor temperature. Door panels and trim vary by finish suffix, while fans, valves, and ice maker parts are shared. The 632 manual and 632 diagram show component positions. For 632 repair guidance by symptom, open the Sub Zero 632 troubleshooting page.
Most Replaced 632 Parts
Evaporator Fan Motor and Uneven Cooling
When the fan stops, cold air stays at the coil and the compartment warms while the compressor keeps running. A noisy fan often has a worn bearing or ice contact. Listen during a cooling cycle; no fan sound means the motor has failed. Replacement fan motors are listed here.
Door Gasket Seal Loss
On tall side-by-side doors, the 632 door gasket wears first at the bottom corners. Do the paper-drag test around each door; any spot with no drag means warm, humid air is getting in, causing frost and long run times. Order a new door gasket for the affected door.
Ice Maker and Water Inlet Valve
Confirm the water supply is on and the freezer is cold before replacing the 632 ice maker. Then test the 632 water inlet valve solenoid for continuity, since a failed valve stops water while the ice maker is fine. Replace the ice maker only after water delivery is confirmed.
Door Switch and Interior Lights or Fans
The door switch turns on the light and, on many builds, pauses the fan while the door is open. A failed switch can leave lights on, which adds heat, or keep the fan off when the door is closed. Test continuity and replace the switch if it does not change state.

632 Side-by-Side Refrigerator FAQ
Why is only one side of my refrigerator warm?
Check that side’s evaporator fan, defrost system, and door gasket first. A problem affecting only one compartment is rarely a compressor failure.
Why did my ice maker stop working?
Confirm the water supply, the freezer temperature, and the inlet valve. A failed valve solenoid stops water to the ice maker and is cheaper to replace than the ice maker itself.
How can I tell if the door gasket needs replacing?
Close the door on a strip of paper at several points. If it slides out with no resistance anywhere, the gasket is no longer sealing and should be replaced.
What does the door switch control?
It turns the interior light on and off and, on many builds, pauses the fan when the door opens. A failed switch can leave the light on or the fan off.
