Mmv4203wb-O Parts

This molded wire support clip secures wiring and small harnesses to the appliance cabinet or components to prevent rubbing, pinching, or contact with moving/heat-producing parts. It helps reduce chafing and electrical wear for safer, more reliable operation. What it does:

• Holds wiring harnesses and individual wires in place to prevent contact with sharp edges, motors, or heating elements
• Minimizes wire movement and vibration that can lead to chafing or broken conductors
• Helps maintain proper routing for consistent connections and component performance
• Commonly used where a small push-fit retainer is needed to secure low-voltage or signal wires

• One wire support clip as shown

• Disconnect power to the appliance before servicing to avoid shock or injury
• Push-fit installation: align clip over wire/harness and press into the mating hole or slot until it snaps in place; clip may require slight flexing
• Inspect surrounding wiring and routing for damage; replace any frayed or exposed wires before reassembly
• If the mounting hole or panel is damaged, use the correct replacement panel or a suitable repair to ensure a secure fit

This piston assembly restores the moving piston used in the appliance's fluid/valve system to help recover proper dispensing and motion. It replaces a worn or damaged piston so the affected function can operate as intended. What it does:

• Replaces the piston that moves inside a valve or dispenser to control fluid or airflow
• Restores proper actuation and sealing that can prevent drips or improper dispensing
• Commonly installed when symptoms include poor dispensing, leaks near the valve area, sticking motion, or unusual noises during operation
• Works as a direct-fit replacement where this OEM piston assembly is specified

• One piston assembly as shown

• Disconnect power (and water supply or gas, if applicable) before starting any repair
• Follow the appliance service manual and use appropriate tools; keep small fasteners and seals organized
• Inspect sealing surfaces and O-rings; replace damaged seals to ensure a leak-free install
• Test the appliance after installation to confirm correct operation

This thermistor is a refrigerator temperature sensor that monitors internal air temperature so the control board can regulate cooling. Replaces a failed sensor to help restore accurate temperature readings and more consistent cooling. What it does:

• Senses internal refrigerator temperature and sends a variable resistance signal to the control board
• Helps the control system cycle the compressor and fans correctly for stable temperatures
• Commonly replaced when refrigerator runs too cold, too warm, or has irregular cooling cycles
• Can address temperature-error codes or defrost control issues when the sensor is faulty

• Disconnect power to the appliance before inspecting or replacing the sensor
• Handle the sensor and wiring harness carefully to avoid damage to the probe or connectors
• Install in the original sensor mounting location and secure wiring away from moving parts

This base is the appliance's lower cabinet section that supports internal components and helps stabilize the unit. It restores a solid foundation so the appliance sits level and protects internal parts from floor contact and debris. What it does:

• Provides structural support for the appliance's internal assemblies and controls
• Helps stabilize the unit and reduce excessive vibration or rocking
• Protects wiring, motors and other components from contact with the floor
• A damaged or cracked base can cause noisy operation, misalignment, or uneven sitting

• Disconnect power (and gas if applicable) before beginning any repair
• Follow the OEM service manual for disassembly and reassembly steps
• Replacement may require removing the cabinet and/or drum; having a second person helps with lifting and alignment
• Inspect and reuse original fasteners only if undamaged; replace any worn mounting hardware

This replacement power cord supplies electricity to the appliance so it can run safely and reliably. It replaces a worn, frayed or damaged cord to restore steady power and reduce risk of electrical problems. What it does:

• Delivers mains power from the outlet to the appliance's internal wiring
• Replaces cords with visible damage, exposed wires, or broken plug ends
• Stops intermittent power or complete loss of power caused by a damaged cord
• Helps prevent arcing and poor connections when original cord has failed

• Always disconnect power at the wall or breaker before inspecting or replacing the cord
• Secure the cord strain relief and ensure wire connections are tight and correctly routed

This transformer provides the low-voltage power needed by the appliance's control and user-interface circuits so systems like the dispenser, ice maker, or control board can operate reliably. What it does:

• Steps down mains power to low-voltage power for control boards and user-interface components
• Restores power to dispensers, ice makers, timers or control modules that have lost low-voltage supply
• Commonly replaced when control circuits are unresponsive, displays are blank, or dispenser functions fail
• Matches OEM function for direct replacement of the failed transformer

• One replacement transformer

• Disconnect all power to the appliance before starting work to avoid shock hazard
• Handle wiring connections carefully; make secure electrical connections and restore grounding

This replacement mounting plate secures internal components so the appliance operates quietly and stays aligned. Replacing a damaged or bent plate helps stop rattling, prevent part movement, and restore proper fit between adjoining parts. What it does:

• Provides a stable mounting surface for nearby components and fasteners
• Prevents parts from shifting or vibrating during operation
• Helps eliminate rattling or noise caused by a loose or bent plate
• Restores correct alignment where the original plate was damaged or deformed

• One replacement plate

• Disconnect power (unplug appliance or turn off circuit) before starting any repair
• Wear gloves and eye protection; edges may be sharp
• Use correct fasteners and torque to avoid bending the new plate;

This reflector directs and shields the oven light and surrounding area, helping maintain safe illumination and protecting the lamp from direct contact with food and heat. Fits behind the interior lamp in compatible ranges. What it does:

• Reflects and directs oven lamp light for improved interior visibility
• Shields the light from splatters and oven heat to protect the bulb assembly
• Helps maintain consistent light positioning after bulb changes or during cleaning
• Common symptom: dim or uneven oven lighting or a cracked/discolored reflector

• One reflector

• Disconnect power to the appliance and allow the oven to cool completely before starting
• Remove the oven light bulb and lens/cover to access the reflector
• Handle carefully to avoid bending or scratching; reassemble lamp components securely

This fixed thermostat senses temperature and opens or closes the electrical circuit to control heating. It replaces a failed temperature-sensing switch to restore proper heating control and safety. What it does:

• Monitors appliance temperature and interrupts power when the set limit is reached
• Prevents overheating by opening the circuit at high temperatures
• Restores normal heating control when a failed thermostat causes no heat or continuous heating
• Works as a safety/limit device in the appliance's heating system

• Disconnect power to the appliance before starting any repair
• Handle the thermostat and sensing element gently; avoid bending or stressing terminals
• Refer to the appliance service manual or OEM instructions for proper placement and mounting
