Kenmore Elite 10644423602 side-by-side refrigerator Parts

Kenmore Elite side-by-side refrigerator model 10644423602 is in the 23 to 25 cu. ft. size class. To get the exact listed capacity for your specific configuration, use the model and serial label inside the fresh-food compartment and confirm the capacity in the 10644423602 owner's manual.

How to find the exact capacity for your unit

Capacity can vary by configuration within the same platform, so we use the model and serial label to match the correct spec.

• Open the refrigerator door and locate the model and serial number label on the inside wall.
• In the manual, look for sections such as “product data,” “product record,” or specifications.
• If the manual lists multiple “model size” groupings, match the one that aligns with your unit.
• Use the same model number when ordering parts like a refrigerator water filter, ice maker, or door bins.

Quick reference: common side-by-side capacity groupings

These are the most common total-capacity groupings you will see for Kenmore side-by-side designs.

Size class (total)	Typical household fit	What changes most
23 cu. ft.	Standard family use	Slightly less shelf and bin volume
25 cu. ft.	Larger storage needs	More usable space in fresh-food and freezer sections

Why it matters

Knowing the correct cubic feet helps when comparing refrigerators and when selecting correctly fitting accessories and parts. For example, filtration and dispenser components can vary by configuration, such as the refrigerator water filter EDR3RXD1.

On Kenmore Elite model 10644423602, the ER/CF error code points to a condenser fan problem. The fan near the compressor is not running correctly or the control is not sensing proper fan feedback, so the refrigerator may run warm or run longer than normal.

What to check first (safe, quick checks)

• Unplug the refrigerator before touching any wiring or the fan area.
• Make sure the condenser fan blade spins freely and is not blocked by dust, packaging, or debris.
• Listen for the fan when the compressor is running; on most side-by-side units, the condenser fan should run with the compressor.
• Check for obvious wire damage or a loose connector at the fan motor and control.
• Clean the condenser area; heavy lint buildup can overheat the compressor compartment and trigger cooling-related faults.

Common causes and what they look like

Likely cause	What you may notice	Typical fix
Condenser fan motor not running	Warm refrigerator temps, hot compressor area	Replace fan motor (if applicable)
Fan blade obstructed or damaged	Rattling, intermittent fan operation	Clear obstruction or replace blade
Wiring/connector issue	Fan works when you wiggle harness, code comes and goes	Repair harness/connector
Control not reading fan feedback	Fan runs but ER/CF returns	Diagnose control and fan circuit

When a part replacement is likely

If the fan is getting power but will not run, or it runs noisy and stalls, the fan motor or related controls are usually the next step. If you are also seeing cooling issues or frost patterns that point to airflow problems, defrost components can contribute to temperature symptoms.

• Use the wiring diagram and diagnostics in the 10644423602 owner’s manual to confirm the test points and expected readings.
• If you are troubleshooting a warm-freezer or warm-fridge complaint along with the code, inspect the defrost system; a failed refrigerator defrost bi-metal thermostat WPW10225581 can contribute to poor cooling and longer run times.

Why it matters

The condenser fan removes heat from the sealed system area. When it fails, the compressor compartment overheats, cooling performance drops, and the refrigerator can struggle to hold safe food temperatures.

On the Kenmore Elite side-by-side refrigerator model 10644423602, defrost is typically controlled by an electronic control (adaptive defrost) rather than a separate, stand-alone defrost timer you can easily point to. For this model family, the defrost control is usually integrated into the main control housing in the fresh food section; use the 10644423602 owner's manual to confirm the control locations and access steps.

Where to look first on model 10644423602

On many Kenmore Elite side-by-side designs like 10644423602, the defrost “timer” function is handled by the control board, so you will be looking for a control housing instead of a small mechanical timer dial.

Check these common locations:

• Fresh food (refrigerator) compartment control area: inside the top control console or control box area
• Back of the refrigerator: behind a rear access cover (some versions place controls there)
• Kickplate/base grille area: less common for electronic defrost, but worth a quick check for service access

How to confirm you have a timer vs. electronic defrost

A quick visual check helps you avoid chasing the wrong part.

What you see	What it usually means	What to do next
Small round dial or slotted shaft labeled “timer”	Mechanical defrost timer	Locate it and test/replace if stuck
No dial; wiring harnesses going to a control board	Electronic adaptive defrost	Focus on control board, defrost heater circuit, and sensors

If you are troubleshooting a defrost problem

If the freezer is frosting up or airflow is weak, the issue is often in the defrost circuit, not a timer.

Start with these practical checks:

• Unplug the refrigerator and inspect the evaporator area for heavy frost buildup
• Make sure air vents are not blocked by food packages
• Check door gaskets for gaps that let humid air in
• If you have a meter, test the defrost sensor and related wiring
• Consider the defrost thermostat as a common failure point; for this model, see the refrigerator defrost bi-metal thermostat WPW10225581

Why it matters

Knowing whether 10644423602 uses a mechanical timer or an electronic adaptive defrost control changes the repair path. A timer-style unit is often a single-part swap; electronic defrost problems usually require testing the defrost thermostat, wiring, and control board logic.
