This replacement idler pulley keeps the drive belt tight and tracking correctly so the drum can rotate smoothly. It restores quiet, consistent operation when the original pulley is worn or seized and causing belt slippage or noise.

• Maintains proper tension on the drive belt to enable smooth drum rotation
• Provides a low-friction surface for the belt to ride on and stay aligned
• Common symptoms of failure: squealing/chirping, belt fraying or coming off, burning rubber smell, or a drum that won't turn
• Replace if the pulley wobbles, binds, or the rim/bearing is worn

• Disconnect power; if gas, shut off the gas supply
• Note belt routing, relieve tension from the idler arm, and remove the belt from the motor pulley
• Remove the retaining hardware from the old pulley, install the new pulley on the idler arm shaft, and re-tension the belt
• Manually rotate the drum to verify smooth belt tracking before reassembly and test run

This idler assembly is the spring-loaded belt tensioner that keeps the drive belt correctly tightened. Replacing a worn or seized idler restores smooth belt tracking, reduces squeal, and helps prevent slippage or loss of drive.

• Maintains proper tension on the drive belt for reliable power transfer
• Helps prevent belt slippage, squealing, or the belt coming off the pulleys
• Supports smooth rotation of the driven components
• Failure symptoms can include noise from the belt path, a frayed or derailed belt, or loss of motion

• Disconnect power and allow all moving parts to stop before servicing
• Access the belt path; relieve belt tension and remove the old idler assembly
• Install the new assembly; ensure the pulley spins freely and the belt is centered in the groove
• Manually rotate the system to verify alignment and clearances before restoring power

This replacement screw secures appliance panels and components so they stay tight and aligned during use. Replacing a missing or damaged screw restores a solid fit and helps eliminate rattles, loose trim, or shifting parts.

• Fastens brackets, panels, trim, or components to the appliance chassis
• Helps correct loose or missing hardware after vibration or service
• Replaces stripped, rusted, or broken screws
• Can reduce rattling noises or misaligned parts caused by missing fasteners

• Disconnect power; for gas appliances, also shut off the gas supply
• Support the part being fastened; start threads by hand to avoid cross-threading
• Use the correct driver size; tighten snugly without overtightening
• Replace hardware with the exact part number to ensure proper fit

A high-limit thermostat that stops the dryer's heating circuit if internal temperatures get too high, helping prevent overheating and protecting heating components. Replaces a failed high-limit thermostat to restore overheat protection. What it does

• Opens the heating circuit when dryer temperature exceeds the thermostat set point to prevent overheating.
• Commonly related symptoms: dryer runs but produces little or no heat, dryer gets unusually hot, or the thermal cutoff repeatedly fails.
• Works as part of the dryer's temperature-safety system to protect heating elements, fuses, and internal wiring.

• One high-limit thermostat

• Disconnect power before accessing the dryer and work only after panels are cool.
• Take a photo or label wires before removal to ensure correct reconnection.
• Test the thermostat for continuity with a multimeter to confirm failure before replacing.
• If other safety devices (thermal fuse, cycling thermostat, element) show symptoms, inspect and test those components too.

Replace a damaged collector duct to restore proper ventilation airflow. This kit channels air from the appliance's intake to the exhaust path, helping reduce leaks, noise, and recirculation for consistent capture performance.

• Directs airflow from the intake/collector to the exhaust duct path
• Helps maintain proper airflow and capture efficiency
• Provides a sealed transition to minimize air leaks and recirculation
• Common symptoms: poor vent suction, smoke/steam lingering, rattling vibrations, visible damage or gaps

• Disconnect power at the breaker; shut off gas before servicing
• Wear cut-resistant gloves—sheet-metal edges can be sharp
• Note airflow orientation and gasket locations; dry-fit before fastening
• Seal joints with UL-listed foil HVAC tape; do not use cloth duct tape

Size: 10-32 inch.

This retaining ring secures a component on a shaft or within a groove so it stays aligned during operation. Replacing a bent, rusted, or missing ring helps stop wobble, noise, and parts working loose.

• Locks into a groove to keep gears, pulleys, wheels, or spacers from sliding off a shaft
• Helps maintain proper spacing and alignment of moving parts
• Common signs of failure: wobbling parts, scraping/rubbing noises, or components that work loose
• Visual clues: deformation, corrosion, or loss of spring tension

• Disconnect power and any utilities to the appliance before service
• Wear eye protection—retaining rings can spring free under tension
• Note the order/orientation of any washers or spacers before removal
• Use appropriate snap-ring or needle-nose pliers and ensure the ring seats fully in its groove

This hex-head sheet metal screw secures appliance panels, brackets, and trim for a tight, rattle-free fit. Replace missing or stripped fasteners to keep covers and components firmly in place and restore proper alignment.

• Fastens sheet-metal parts, brackets, and trim using a hex drive
• Replaces worn, rusted, missing, or stripped screws
• Helps reduce vibration and rattling from loose panels
• Common signs you need this fastener: head or threads stripped, screw won't tighten, panel or handle coming loose

• Unplug the appliance before service; turn off water supply if working near water lines
• Use the correct nut driver or socket to avoid rounding the head
• Replace one fastener at a time to maintain alignment; do not overtighten
• Match screw type/length to the original location as specified by the manufacturer

Specs: No.8X1/2 HEX WASHER HEAD

An adjustable leveler that supports and raises or lowers the appliance to help stabilize it on uneven floors. Restores proper alignment to reduce rocking, vibration, and door misalignment for improved performance and safety. What it does:

• Provides height adjustment to level the cabinet and prevent rocking
• Helps doors close and seal correctly by correcting leaning or unevenness
• Reduces vibration and movement that can cause noise or wear
• Simple turn-to-adjust design for fine tuning appliance position
