Tbx21ni Parts

This evaporator fan blade mounts on the freezer fan motor and circulates air across the evaporator coils. Replacing a cracked or warped blade restores proper airflow for even cooling and more consistent temperatures throughout the refrigerator.

• Moves chilled air from the evaporator through the ducts to both compartments
• Helps maintain uniform temperatures and overall cooling performance
• Common symptoms of a faulty blade: weak airflow, poor cooling or warm spots, rattling/scraping noises from the freezer, longer run times
• Visual signs include a cracked hub, loose fit on the shaft, or broken/missing vanes

• Disconnect power before servicing
• Remove freezer shelves/ice bin and the rear panel to access the fan assembly
• Pull the old blade straight off the motor shaft; align the hub and press the new blade on until fully seated
• Verify blade orientation and free rotation inside the shroud before reassembly

Nut for 1/4 inch tubing.

This mobility wheel is the small cabinet roller that helps your refrigerator glide for cleaning or service. Replacing a worn, cracked, or missing wheel restores smooth movement and supports proper leveling and positioning. What it does:

• Supports the base of the cabinet and allows the unit to roll when repositioning
• Replaces wheels that are cracked, flat-spotted, broken, or missing
• Common symptoms: refrigerator is hard to move, drags or scrapes, sits unevenly, or shows visible wheel damage
• Aids in pulling the appliance out for maintenance or cleaning

• 1 mobility wheel

• Disconnect power and shut off the water supply before moving the appliance
• Use two people and protect flooring; raise/adjust leveling legs to relieve weight from the wheel
• Access the base/roller bracket, remove the damaged wheel, and install the new wheel securely
• Lower and re-level the unit, reconnect utilities, and verify smooth movement

This cable clamp secures refrigerator wiring to the cabinet, keeping harnesses organized and protected. Replacing a missing or damaged clamp helps prevent chafing and vibration noise while maintaining proper clearance from fans and other moving components.

• Anchors wire harnesses in their designed routing
• Helps prevent insulation wear from rubbing or vibration
• Keeps wires clear of sharp edges and moving parts
• Common signs it's needed: missing/broken clamp, loose or dangling wires, or new rattling/buzzing noises

• Disconnect power before servicing
• Access the clamp location and note original wire routing
• Position the clamp and secure with the existing fastener; do not overtighten
• Ensure wires aren't pinched and have clearance from the fan/compressor before restoring power

This vinyl sleeve fits over a rod, tube, or wire in the refrigerator to protect and cushion contact points. It reduces wear and vibration and helps keep components aligned for smooth, reliable operation.

• Provides a protective barrier at contact points to prevent abrasion or marring
• Helps maintain spacing and alignment for a snug, proper fit
• Cushions to damp vibration and reduce rattles or squeaks
• Replace if the sleeve is missing, cracked, hardened, or if components feel loose or make noise

• Disconnect power; turn off the water supply if working near water lines
• Note the sleeve's original location and orientation; take a photo for reference
• Remove the old sleeve and any debris; slide the new sleeve into the same position
• Check clearance and resecure related parts before restoring power

Size: 10-16 ab.

This trough drain collects and channels defrost and condensation water from the evaporator area to the drain system, helping prevent leaks and pooling inside the refrigerator. It restores proper water flow and reduces standing water. What it does:

• Collects defrost/condensation runoff from the evaporator area and directs it to the drain pan.
• Helps prevent water pooling inside the fridge or under crisper drawers.
• Reduces ice buildup and musty odors caused by trapped moisture.
• Replaces cracked or warped troughs that allow leaks or improper drainage.

• Disconnect power to the appliance before beginning any work.
• Remove food, shelves and the evaporator cover/pan as required for access; follow the service manual for your model.
• Clean the drain tube and drain hole before installing to ensure proper drainage.

Includes 12 screws. Size: 8-18 ab.

8-18 CA HX 1/2 S

This replacement screw is used in refrigerators to fasten specific components. Replace a lost or damaged fastener to restore a secure, factory hold so brackets, panels, or covers stay properly mounted and rattle-free.

• Secures the designated component per your model's parts diagram
• Replaces missing, stripped, or corroded hardware
• Helps eliminate looseness, vibration, or rattling from unsecured parts
• Supports proper alignment and fit after service

• Disconnect power to the refrigerator before servicing
• Match this screw to the original location using your model's parts diagram
• Hand-start threads to avoid cross-threading; tighten snugly without overtightening
• Use the correct driver for the screw head style

This small hardware clamp is used on select refrigerators to secure tubing or wiring to the cabinet or frame. Replaces a missing or damaged clamp to keep lines stable, reduce vibration, and help prevent rubbing or leaks.

• Secures small water tubing or electrical harnesses along the cabinet/frame
• Helps prevent vibration, rattling, and abrasion of lines
• Maintains correct routing to keep lines clear of moving or hot components
• Common clues: loose or noisy lines, chafing marks, or moisture near tubing connections

• Unplug the appliance and shut off the water supply before servicing
• Note the original location and routing; take a photo for reference
• Reuse the existing mounting screw/fastener if required; tighten only enough to hold without crushing tubing
• Restore power and water, then run and inspect for vibration and leaks

Size: 8-32 t. Includes 12 screws.

This wire clip secures a wiring harness to the appliance cabinet to prevent rubbing, pinching, or loose connections. Replacing a worn or broken clip helps restore proper wire routing and reduces the risk of electrical contact issues. What it does:

• Holds wiring harnesses in place to prevent chafing and stress on connections
• Keeps wires routed away from sharp edges, moving parts, and heat sources
• Helps stop intermittent electrical problems caused by loose or strained wires
• Reduces risk of arcing or shorting from wires rubbing on metal components

• One wire clip

• Always disconnect power (unplug or switch off circuit breaker) before servicing electrical components
• Remove any panels or obstructions to access the damaged clip, then release the harness and snap the replacement clip into the original mounting location
• Verify wires are seated properly in the clip and routed clear of moving or hot parts before restoring power
• If wiring or connectors are damaged, replace or repair those components rather than relying on the clip alone

Replacement screw that secures panels, trim and internal brackets to keep appliance components stable and rattle-free. Use when originals are missing, stripped, or broken to restore proper fit and safe operation. What it does:

• Secures panels, control housings, trim and small brackets so parts stay aligned and stable.
• Replaces missing or damaged fasteners that cause rattling, vibration, or loose assemblies.
• Keeps electrical and mechanical components properly positioned for reliable operation.
• Intended as a direct replacement where the OEM screw specified for the application is required.

• Disconnect power and unplug the appliance before starting any repair.
• Use the correct screwdriver or bit and seat the screw squarely to avoid stripping the head or threads.
• Do not overtighten—stop when snug to prevent damage to panels or plastic components.
• Keep removed screws organized; replace only with the identical OEM screw for proper fit.
