Ikea Refrigerator Terminal Block, Receptacle Parts

The Defrost Thermostat and Wiring Harness is an OEM part for Whirlpool refrigerators. This part ensures that the refrigerator's evaporator coils do not become overly frosty, thereby maintaining optimal air flow and cooling efficiency throughout the unit.  

Causes for issues with the defrost thermostat and wiring harness often include electrical failures, such as short circuits or broken wires, wear and tear on the thermostat, or a malfunction that prevents it from accurately sensing temperature changes.

Symptoms of a malfunctioning Defrost Thermostat and Wiring Harness include:

• Excessive frost buildup on the evaporator coils
• The refrigerator or freezer compartment becoming too warm
• The refrigerator running continuously without cycling off
• Water leaking inside the refrigerator due to ice melting and not draining properly

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

This replacement wire harness routes electrical power and control signals between components in your appliance. Replacing a damaged harness helps restore reliable operation and prevents intermittent electrical issues caused by broken or overheated wiring. What it does:

• Distributes power and signals between the control, motors, sensors, and other components
• Helps resolve issues like components not running, intermittent operation, or features losing power
• Addresses visible damage such as burnt, melted, pinched, or frayed wires/connectors
• Helps when diagnostics indicate open/shorted circuits in the wiring

• One wire harness assembly

• Disconnect power to the appliance before servicing; shut off water or gas if applicable
• Photograph/label each connection and follow the original routing to avoid pinch points or heat sources
• Release locking tabs and pull on connector housings—do not pull on the wires
• After installation, ensure all connectors are fully seated and wires are secured away from moving or hot parts

This wire harness provides the electrical connection between the ice maker module and the refrigerator's control/power system, restoring reliable power and signal delivery for normal ice-making operation. What it does:

• Connects the ice maker module to the main power and control circuits so the ice maker can cycle and produce ice.
• Replaces damaged, frayed, or loose wiring that can cause intermittent operation or a non-working ice maker.
• Helps resolve symptoms such as the ice maker not powering up, not cycling, or producing little to no ice.
• Restores proper connector alignment and secure signal paths to prevent electrical faults.

• Disconnect power to the refrigerator before attempting any repair to avoid shock or injury.
• Inspect connectors and routing; replace only if the harness and connectors are the confirmed faulty components.
• Use basic hand tools and avoid cutting or splicing unless instructed by the service manual; improper splices can cause failures.

The Wire Harness is an OEM part for Whirlpool refrigerators. It is a critical component that contains all the wiring between electrical controls, motors, sensors, and other components inside the refrigerator. The wire harness allows communication and power transfer throughout the appliance.

Symptoms of a bad wire harness include:

• Lights or displays not working properly   
• The refrigerator not starting cool cycles or completing them
• Strange noises coming from motors or other areas  
• Error codes appearing on the control panel

Causes of a bad wire harness can include severed or damaged wires from normal wear and tear over time, improper installation, or exposure to moisture.

This OEM Whirlpool wire harness replacement ensures electrical signals are conducted smoothly throughout the refrigerator. It prevents disruption and allows for proper operation. This OEM replacement is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
