Screw: 8-16 x 3/8 inch.

This thermostat retainer clip secures the defrost thermostat to the evaporator tubing in your refrigerator or freezer, maintaining firm contact for accurate temperature sensing and dependable defrost operation.

• Holds the thermostat firmly against the evaporator line for proper temperature feedback
• Helps prevent a loose or dangling thermostat that contribute to frost buildup and poor defrost performance
• Restores correct mounting when the original clip is cracked, bent, or missing
• Common signs include a broken clip or a thermostat not attached to the coil

• Disconnect power to the appliance before servicing; wear cut-resistant gloves
• Access the evaporator compartment; remove accumulated frost/ice as needed without prying on coil fins
• Position the thermostat body flat against the tubing and snap the retainer over it, avoiding pinched wires or damaged fins
• Confirm a secure fit and proper wire routing before reassembling and restoring power

This silicone lubricant is used during appliance service to condition rubber seals and O-rings, especially in dishwashers. It eases installation and helps new seals seat properly for a reliable, leak-resistant connection on pumps, valves, and hose fittings.

• Lubricates rubber seals, O-rings, and gaskets to prevent rolling, tearing, or binding during assembly
• Helps seals seat correctly to support leak-resistant joints
• Aids insertion of hoses, plastic fittings, and pump components
• Helpful when reassembling sump, diverter, inlet, and drain connections
• Common signs it may be needed: difficulty installing seals, seals that dislodge, or seepage after a seal replacement

• Disconnect power and water before servicing the appliance
• Clean and inspect mating surfaces; replace any cracked, flattened, or cut seals
• Apply a light, even film to the rubber part only; avoid over-application
• Wipe away excess; do not use lubricant to compensate for damaged seals—replace them

This replacement ejector is the plastic arm that pushes harvested ice cubes out of the ice mold and into the storage bin, helping restore proper ice ejection and reduce ice that sticks inside the tray. What it does:

• Pushes ice cubes out of the ice mold during the ice maker's harvest cycle.
• Works with the ice maker's motor/gear assembly to advance cubes into the bin.
• Replaces worn, cracked, or broken ejector arms that can leave ice stuck in the mold.
• Can help address symptoms such as cubes that don't eject, partial fills, or frequent ice jams.

• Disconnect power to the refrigerator before servicing to prevent electrical shock.
• Remove the ice bin and follow the OEM ice maker removal steps to access the ejector.
• Handle plastic components carefully to avoid cracking; inspect gears, mounts, and the ice tray for related wear.

Color: Stainless steel

This replacement ice cube tray is a direct-fit plastic tray designed to hold and release ice cubes in compatible top- or bottom-freezer refrigerators. Restores convenient ice storage and simple manual ice removal. What it does:

• Holds water in separate cavities so ice cubes form evenly.
• Flexes slightly for easier ice release to reduce twisting or chipping.
• Replaces cracked, warped, or missing trays that cause leaking or uneven freezing.
• Helps prevent contamination from freezer debris when used as intended.

• Remove old tray and wipe area clean before installing the new tray.
• Fill tray with water on a level surface and place flat in the freezer to freeze.
• Handle carefully when removing ice to avoid spills; do not force with sharp tools.
• Clean tray before first use and as needed; follow refrigerator manufacturer's care guidance.

This is a replacement mounting screw for securing appliance components and panels. It restores proper fastening where a missing or stripped screw causes loose parts or rattling. What it does:

• Fastens panels, brackets, or small components to restore secure attachment
• Prevents vibration and rattling caused by loose or missing fasteners
• Replaces stripped or lost factory screws to maintain original fit
• Matches OEM fit for the specific mounting location when the part number is specified

• Use the matching screw location and size specified by the parts diagram
• Hand-start threads to avoid cross-threading; tighten securely but do not overtighten
• Disconnect power to the appliance before removing panels or components
• If threads are damaged, replace with correct OEM screw—do not force a mismatched fastener

This clamp secures flexible hoses to fittings to maintain a tight seal and prevent leaks. Use it to replace a worn or loose clamp to stop water or air seepage and restore proper hose attachment. What it does:

• Holds a washer, dryer, or appliance hose firmly to a barb or fitting to prevent slipping
• Helps maintain a watertight or airtight connection to reduce leaks and drips
• Replaces corroded, cracked, or stretched clamps that no longer grip reliably
• Supports normal appliance operation by keeping fluid/air flow contained

• One clamp

• Inspect the hose and fitting; replace the hose if damaged before installing the clamp
• Position clamp over the hose barb and tighten evenly; avoid over-tightening that can cut the hose
• Disconnect power and water supply before servicing any appliance components

Size: 8-32 x .312 inch.

This motor overload protector helps stop the motor when it overheats, protecting the appliance from damage and preventing unsafe operation. It's a small, replaceable safety device commonly used on motors and compressors. What it does:

• Interrupts motor power if the motor draws excessive current or overheats
• Helps prevent motor burnout and potential electrical hazards
• Can cause a no-start or humming motor when the protector has failed
• May reset automatically or require replacement depending on design

• Disconnect power before accessing or replacing the part
• Handle terminals carefully and match wiring/terminal placement exactly
• Use only the specified replacement part; do not bypass or modify the protector

This is a replacement hex nut used to secure appliance components and fasteners. It restores a tight, reliable connection where a worn or missing nut causes loose panels, trim, or bracketing. What it does:

• Secures threaded studs, bolts, or fasteners to keep panels and components in place
• Restores proper fastening when original nut is stripped, corroded, or lost
• Helps eliminate rattling, vibration, or loose parts caused by a missing/failed nut
• Compatible with the appliance locations that use a standard hex nut for mounting

• Turn off and unplug the appliance before accessing interior panels or fasteners
• Use the correct wrench or socket size to avoid rounding the nut
• Replace only like-for-like nuts; if thread damage is present, inspect and replace the mating bolt/stud as needed

This ball sleeve guides and supports the valve ball inside the water/dispensing assembly to help maintain a proper seal and smooth movement. Replacing a worn sleeve restores reliable valve operation and reduces intermittent leaks or flow issues. What it does:

• Positions and protects the valve ball for consistent seating and sealing
• Prevents wear between the ball and valve bore to maintain proper flow control
• Helps stop dripping, leaking, or inconsistent dispensing caused by a damaged sleeve
• Works as the mating surface for the ball to ensure smooth operation

• One ball sleeve

• Disconnect power and water supply before starting any repair
• Replace only with the correct part number to ensure proper fit and seal
• Inspect surrounding valve components and seals; replace if worn or damaged
• Test for leaks and proper operation after reassembly
