Wcfh6600hbb Parts

Defrost heater that melts frost and ice from the evaporator during the defrost cycle, helping restore proper airflow and efficient cooling. Use when frost buildup or defrost-cycle failures are causing reduced cooling performance. What it does:

• Heats the evaporator fins during the defrost cycle to remove accumulated ice and frost.
• Restores normal airflow so the refrigerator can cool evenly and avoid long run times.
• Commonly replaced when you see heavy frost buildup, poor cooling, or repeated defrost errors.
• Works as part of the defrost system alongside the defrost thermostat/timer or control board.

• Disconnect power to the appliance before testing or installing to avoid shock.
• Handle the evaporator fins carefully to avoid damage; follow OEM instructions for routing and securing the heater.

This overload protector is a thermal motor protector that cuts power if the dryer motor overheats, helping prevent motor damage and unsafe operation. Replace a failed unit to restore the motor's built-in overheating protection. What it does:

• Senses excessive motor temperature and interrupts motor power to prevent damage.
• Common symptom: dryer may not start or the motor hums but won't turn when the overload has failed.
• Helps stop repeated motor overheating and can prevent associated electrical faults.
• Works as the motor's thermal safety device; must be replaced if open or damaged.

• Disconnect power to the appliance before servicing to avoid shock or injury.
• Transfer wiring and mounting exactly as removed; do not bypass the protector.
• Inspect motor and blower for obstructions or causes of overheating before reassembly.

This replacement screw secures appliance panels, brackets, and components. Using the correct size restores a snug fit to reduce vibration, prevent loosening, and keep assemblies properly aligned during operation. What it does:

• Fastens sheet metal and component brackets in designated locations
• Replaces missing, stripped, or corroded hardware
• Helps eliminate rattling and vibration from loose panels
• Maintains proper alignment of covers and assemblies

• 1 screw

• Disconnect electrical power; shut off water or gas supplies if applicable
• Match length/thread to the original; replace one fastener at a time to preserve alignment
• Start by hand to avoid cross-threading; use the correct driver size
• Snug firmly but do not overtighten to prevent stripping

This wire harness routes electrical signals between the appliance control and internal components, restoring reliable communication and power paths. It replaces damaged or burned wiring to help resolve intermittent or failed control functions. What it does:

• Reconnects control board circuits to motors, switches, sensors, or terminal blocks
• Restores proper signal and power flow when wiring is damaged or shorted
• Helps stop intermittent operation, unexplained shutdowns, or control non-responsiveness
• Provides OEM-style replacement wiring and connector fit for direct swap

• Always disconnect power (unplug or shut off circuit breaker) before installing
• Handle connectors by the housing; avoid pulling on individual wires
• Confirm connector orientation and secure all clips and fasteners for strain relief
