Parts for Whirlpool WRB543CMJV00: Liner Parts

The Refrigerator Door Switch is an OEM part for Whirlpool refrigerators. This switch monitors the opening and closing of the refrigerator door, activating lights and functions as needed while also keeping track of door activity for diagnostics purposes. 

Causes of failure may be from normal wear and tear over time, moisture damage, or impact if the door is accidentally slammed.

Symptoms of a bad door switch include:

• Lights not turning on/off with door movement  
• Dispensers or ice/water not working properly
• Cooling and freezing performance affected
• Error codes related to door operation

This OEM replacement part is compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models as well.

This multiflow front cover directs chilled air inside the refrigerator compartment and provides a finished, corrosion-resistant appearance. It replaces a damaged or discolored diffuser cover to restore proper airflow distribution and interior looks. What it does:

• Covers the multiflow air outlet to help distribute cold air evenly in the fresh-food compartment
• Protects internal airflow components from bumps and debris
• Restores the refrigerator's factory appearance when original cover is cracked, warped, or faded
• Works with existing multiflow diffuser components to maintain intended airflow patterns

• One multiflow front cover (chrome frost finish)

• Verify power is off and food is removed or protected before accessing interior panels
• Usually snaps or screws into place behind the refrigerator interior trim; use proper fasteners and avoid overtightening
• Handle plastic parts carefully to avoid cracking; replace any damaged clips during reassembly

This damper is the airflow gate that opens and closes to control air movement through the appliance's vent/duct path. Replacing a worn damper restores proper circulation and helps eliminate drafts and rattling from a loose or broken flap. What it does and common symptoms:

• Opens/closes a baffle to meter airflow through the air channel
• Helps maintain consistent air circulation and appliance performance
• Symptoms can include weak airflow or a constant draft when off
• Clicking, flapping, or rattling noises near the vent/duct area
• Visible damage or a stuck/broken flap at the damper

• One damper assembly

• Disconnect power before servicing; if applicable, shut off gas supply
• Access the damper behind the relevant cover/air duct; note orientation before removal
• Transfer any seals/clips from the old unit and ensure a tight, even seal on install
• After reassembly, restore power and verify the baffle moves freely and airflow is correct

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
