This wire harness routes power and signals between the appliance control and components to restore reliable electrical connections and normal operation. It replaces damaged or worn wiring to help stop intermittent power, unresponsive controls, or component failures. What it does:

• Connects control board to motors, switches, sensors and other electrical components
• Restores broken or frayed circuit paths that cause intermittent operation or no power
• Replaces burned, corroded, or loose connector ends that cause poor contact
• Helps prevent shorting or blown fuses when original wiring is compromised

• Disconnect power (unplug or turn off breaker) before starting any repair.
• Handle connectors by the housing; avoid pulling on individual wires.
• Route and secure the harness the same way as the original to prevent pinching or heat exposure.

This is a replacement screw designed to work with a wide range of household appliances. It is used for many purposes in these appliances, from holding body panels together to securing electronics into control boards. However, screws are subject to damage through corrosion, impact, and improper installation/removal. In most cases, the primary damage to this screw is through corrosion – it may become rusted or corroded in place, depending on the appliance and the maintenance provided during its lifespan. The screw may also be stripped or rounded due to improper removal or installation. If the screw is damaged, lost, or corroded in place, it will need to be replaced. In most cases, removal will require nothing more than a Phillips head screwdriver or the appropriately sized socket with a ratchet. However, if the screw is damaged, it may require a tap set to remove it from its mounting location. Note that this is a genuine OEM replacement screw made from durable, high-quality metal, and is sold individually. It fits Whirlpool, Maytag, Roper, Estate, Amana, Crosley, and Thermador appliances. It is used in over 150 machines, ranging from washers and dryers to air conditioners.

This wire harness routes power and signals between an appliance's control and internal components to restore reliable electrical connections. Replacing a damaged harness helps stop intermittent operation and power loss for safer, more consistent performance. What it does:

• Routes power and control signals between the control board and internal components.
• Replaces frayed, cut, or burned wiring that can cause intermittent operation or component failures.
• Helps address symptoms such as loss of power to controls, unresponsive cycles, or devices that won't start.
• Prevents loose or corroded connections that can create intermittent faults.

• Always disconnect the appliance from power (unplug or switch off circuit breaker) before servicing.
• Match each connector to its mating plug and follow the OEM wiring diagram for routing and color codes.
• Secure the harness away from heat sources and moving parts; use existing clips and fasteners.

The Main Control Board is an OEM part for Whirlpool washing machines. As the central processing unit, it controls all functions of the washer such as cycle selection, temperature settings, spin speed, and sensor detection. The main control board monitors operations and safety features throughout each cycle. 

Causes of a bad main control board include circuit failures, component degradation over time, or water damage from leaks. 

Symptoms of a bad main control board include:

• The washer not starting cycles or powering on  
• Failure to complete cycles and unexpected shutdowns
• Inability to select cycle options or make setting changes
• Flashing error codes 

This OEM Whirlpool replacement part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
