General Electric Washer Screws, Nuts, Washers

This screw-pulley is a small-drive pulley fastener used on select appliance assemblies to secure pulley components and maintain correct belt/drum alignment. It replaces worn or damaged pulley screws to restore proper pulley attachment and reduce noise. What it does:

• Secures a pulley to its mounting shaft so belts and drum components track correctly
• Helps prevent pulley wobble, slipping, and related noise during operation
• Restores a missing or damaged pulley fastener that can cause belt misalignment
• Used where a specific high-strength (10.9 class) screw/pulley fastener is required

• Basic hand tools required; verify the appliance is fully powered off and unplugged before starting
• Support moving components (drum/belt) to prevent shift during removal/installation
• Tighten to secure fit without over-torquing; replace any damaged mating hardware

A single hex washer head screw used to secure panels and components on compatible appliances. Durable and straightforward, it replaces stripped or missing fasteners to restore proper fit and alignment. What it does:

• Fastens appliance panels, trim, or internal components with a hex washer head drive.
• Holds parts in place to prevent rattling, gaps, or misalignment.
• Common replacement for damaged, corroded, or missing screws.
• Works wherever the exact hex washer head screw specification is required.

• Use the correct driver to avoid stripping the screw head; apply steady pressure while turning.
• Tighten until snug—do not overtighten to avoid damaging threads or plastic parts.
• Disconnect power and follow appliance safety guidelines before accessing internal components.

A silicon controlled rectifier (SCR) used to switch and regulate AC power to heating and high-current circuits in appliances. Replaces a failed SCR to restore proper power control and cycling of the affected element. What it does:

• Acts as an electronic switch to control power flow to heating elements or motors
• Enables timed or regulated delivery of current for proper operation
• Can fail open or short, causing no heat, continuous heat, or erratic cycling
• Commonly used on control boards or power modules as the line-side switching device

• One silicon controlled rectifier (ST4-25)

• Always disconnect power to the appliance before beginning any repair
• Observe static-sensitive device precautions and avoid touching terminals directly
• Verify correct orientation and secure mounting per the service diagram before reassembly
