Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for Kenmore Refrigerator Damper Control Assembly Replacement Guide?

Q: What does Kenmore Refrigerator Damper Control Assembly Replacement Guide mean?

Warm fridge, frozen food, or no airflow? A faulty damper control assembly (air diffuser) fails to regulate cold air. Replacing it restores temperature control.

Q: How do I fix Kenmore Refrigerator Damper Control Assembly Replacement Guide?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Kenmore Refrigerator Damper Control Assembly Replacement Guide — What This Part Does

The damper control assembly is the motorized air gate that meters cold air from the freezer into the fresh-food compartment. It opens and closes a flap to control how much cold air flows through, keeping your refrigerator at the right temperature while the freezer stays frozen. The assembly usually includes the damper motor, the flap mechanism, and often a thermistor sensor that tells the control board when to open or close the damper.

This part fails when the motor wears out and can no longer move the flap, when the flap itself gets stuck from ice buildup or broken plastic tabs, or when the attached thermistor sensor goes bad. Harness connectors can also corrode or come loose. Once the damper stops working correctly, the refrigerator section either gets too warm (damper stuck closed) or freezes food (damper stuck open), and you lose proper temperature control between compartments.

Signs It Needs Replacing

Refrigerator compartment too warm The fresh-food section runs warmer than the set temperature because the damper is stuck closed and not letting enough cold air in from the freezer.
Food freezing in the refrigerator section Items freeze or get ice crystals because the damper is stuck open, allowing too much cold air to flow continuously into the fridge compartment.
No air movement at the diffuser vents You feel no cold air coming through the diffuser grille in the refrigerator, indicating the damper flap is not opening at all.
Clicking or buzzing from the damper area The damper motor makes repeated clicking or buzzing sounds as it tries to move a jammed or broken flap.
Freezer works but fridge does not The freezer maintains temperature normally while the refrigerator section stays warm, pointing to a failed damper that is not allowing air transfer.
Ice buildup around the damper housing Frost or ice forms around the diffuser or damper assembly, physically blocking the flap from moving and disrupting airflow.

How to Replace It

Unplug the refrigerator from the wall outlet to cut all power before you start any repair work.
Find your model and serial number on the metal plate (usually inside the fresh-food section on the side wall or ceiling) and use it to order the correct damper control assembly for your Kenmore refrigerator.
Remove the refrigerator-section diffuser cover or grille by releasing the plastic tabs or removing screws, depending on your model.
Unplug the wire harness connector from the damper assembly and note the routing so you can reconnect it later.
Remove any additional covers, screws, or brackets securing the damper housing (some models require removing a freezer-side duct panel or repositioning the ice maker to access all mounting tabs).
Pull the old damper control assembly out of its mounting clips or screw holes and inspect the flap, motor, and thermistor for visible damage or ice.
Position the new damper assembly into the mounting clips or screw holes, making sure the flap moves freely and the thermistor (if attached) is correctly seated in its pocket.
Reconnect the wire harness to the new damper assembly, ensuring the connector clicks firmly into place.
Reinstall all covers, grilles, and panels in reverse order, then plug the refrigerator back in and set the fresh-food temperature to your desired setting.
Wait 10 to 15 minutes, then check that the damper flap opens when you lower the temperature setting and closes when you raise it, confirming the new assembly is working correctly.

The Part You Need

Part	Notes
Refrigerator damper control assembly (air diffuser)	Amazon \| Also called thermostat damper control or air diffuser. Find your exact Kenmore model number on the metal serial plate inside the refrigerator and cross-reference it with the OEM or aftermarket part number, as Kenmore uses multiple damper designs across different platforms.

When to Call a Pro

Call a technician if you are not comfortable unplugging harnesses or removing multiple interior panels, or if the new damper still does not open and close after installation (which can mean a control-board or wiring fault upstream). If you see heavy ice buildup that keeps returning after defrosting, you may also have a defrost-system problem that needs diagnosis. A pro can also perform electrical resistance checks on the damper motor (typically around 1 kΩ to 10 kΩ on some motors, though this is a generic troubleshooting value, not a factory spec) to confirm the motor is good before you buy a new assembly.
