W10110378 — What Part Is This and How to Replace It?

Understanding the Problem

Brief explanation: I couldn't confidently match W10110378 to a single, specific component from my internal parts database without the appliance make and model. Many manufacturers reuse similar part numbers and the same number can refer to different components across brands and appliance types. To give an exact diagnosis and replacement instructions I need the appliance brand (Whirlpool, Kenmore, Maytag, etc.) and the appliance model number (from the tag). Until you provide that, follow these numbered diagnostic and repair steps to identify and replace the part yourself: 1) Locate the part number on the old component: remove the access panel or door needed to view the suspect part and look for stickers, stamps, or molded numbers. If W10110378 appears on the component, photograph it (close-up) for reference. 2) Record appliance model and serial number: find the model/serial tag (usually inside the door frame, on the back, or behind a kickplate). Use that model number when searching parts diagrams online. 3) Check the exploded parts diagram: go to the manufacturer parts site (e.g., repairpartsdirect, searspartsdirect, partselect) and enter your model number. Match the shape and mounting location to the diagram item that lists W10110378. 4) Identify symptoms tied to the physical location: for instance, if W10110378 is on the door latch assembly, expect door-not-locking or no-start symptoms. If it’s an electrical board, expect dead appliance or intermittent operation. Match the observed symptom with the part location. 5) Test the component before replacing: if it’s electrical, disconnect power and test continuity with a multimeter. If it’s mechanical (latch, roller, valve), inspect for broken plastic, excessive play, rust, or seized movement. 6) Order the correct part: use the model number + part number to order from the manufacturer or a reputable parts seller. Confirm compatibility with your specific model. 7) Basic replacement steps (generic): a) Unplug the appliance or shut off power at the breaker. If a gas appliance, shut the gas off and disconnect per local codes. b) Turn off water supply for washers/dishwashers when applicable. c) Remove the appropriate access panel(s) to reach the part — use the exploded diagram for panel removal order. d) Photograph wiring and connector locations before disconnecting. Label harnesses with tape if necessary. e) Remove mounting screws/fasteners and carefully extract the old part. f) Transfer any brackets, gaskets, or fittings to the new part if required. g) Install the new part, reconnect wiring/harnesses, and fasten securely. h) Reassemble panels, restore power (and gas/water if applicable), and run a test cycle to confirm repair. Safety note: Always disconnect power before opening panels. If you are unsure about gas connections, electrical testing, or working with high-voltage parts, stop and contact a qualified technician. Provide the appliance brand and full model number and I will give an exact, part-specific replacement guide.

Common Symptoms

Symptoms depend on which component W10110378 refers to—common signs include: appliance won’t start or complete cycles, door won’t latch, strange noises, leaks, or intermittent operation. Provide brand and model for exact symptoms.

Common Causes

• Normal wear and tear (broken plastic, worn contacts, worn bearings)
