Parts for Whirlpool WRT112CZJB00: Liner Parts

This freezer damper control regulates cold airflow from the freezer into the refrigerator compartment, helping maintain proper temps and balance cooling. Replaces a faulty damper to restore normal air distribution and operating performance. What it does:

• Opens and closes the damper to control refrigerant-cooled airflow between freezer and fridge compartments
• Commonly replaced when the refrigerator compartment is too warm or the freezer runs unusually cold
• Can correct uneven cooling, temperature drift, or compressor overrun caused by a stuck or inoperative damper
• Operates with the freezer thermostat/board to modulate airflow as conditions change

• One freezer damper control assembly

• Disconnect power before starting — always unplug the appliance or shut off power at the breaker
• Handle panels and shelves carefully to access the damper; basic hand tools are typically required
• Note damper orientation and wiring location before removal to ensure correct reassembly

The Control Knob is an OEM component specifically designed for Whirlpool refrigerators. Found on the electronic control panel inside the Fresh Food compartment, the control knob allows for manual temperature adjustments.

Causes of a bad control knob include cracks or wear to the plastic housing from repeated use over time. Damage or stripping of the mounting stems is also possible due to accidental force.

Symptoms of a bad control knob include:

• Difficulty adjusting temperature settings manually
• Knob movement unrelated to temperature displays
• Loose, wobbly, or detached knob assembly

Compatible with Whirlpool, KitchenAid, Jenn-Air, and select Maytag French door models.

This thermistor cover shields and positions the refrigerator's temperature sensor so it reads cabinet air accurately. Replacing a cracked or missing cover helps restore stable temperatures and normal cooling performance.

• Holds the thermistor in place and shields it from direct airflow for accurate temperature sensing
• Helps prevent erratic temperatures, overcooling/undercooling, or long run times caused by an exposed sensor
• Commonly replaced when the original cover is cracked, loose, or missing
• Supports consistent temperature control by ensuring proper sensor placement

• Disconnect power before servicing
• Remove shelves/bins as needed to access the sensor location
• Align the thermistor and seat the cover fully; engage tabs or reuse existing hardware per model
• Avoid pinching the sensor or wiring and verify the cover is snug
