Understanding the Problem
WP3387747 is presented as a Whirlpool-style part number but without the appliance make/model it’s impossible to guarantee which component it references. Many Whirlpool part numbers (WP#######) match different parts across washers, dryers, refrigerators, ranges and dishwashers. Misidentifying a part can lead to ordering the wrong replacement, wasted time, and unresolved appliance problems. The best approach is to confirm the appliance model number (usually on a tag inside the door, on the back panel, or behind the kickplate), then use the model to search official parts diagrams or reliable parts suppliers. Once you’ve identified the exact component WP3387747 corresponds to, you can follow targeted troubleshooting steps—visual inspection first, then electrical tests (continuity, resistance) and functional tests—before replacing the part.
Common Symptoms
Symptoms depend on the actual part but common signs that a part has failed include: appliance won’t start, intermittent operation, unusual noises, leaks, error codes, or a specific function not working (e.g., no heat, no spin, no dispense).
Common Causes
- Misidentifying the part because the wrong model number or part number was used
- Normal wear and tear or mechanical failure of the actual component
- Electrical failure from shorted wiring, power surges, or control board issues

Frequently Asked Questions
How do I confirm WP3387747 is the correct replacement for my appliance?
Find your appliance model number (on the door frame, behind the kickplate, or on the back). Enter the model number and WP3387747 on the official Whirlpool parts lookup or a trusted parts retailer to see the exploded parts diagram and verify compatibility. If the part image and connector/bolt locations match what’s on your appliance, it’s likely correct. When in doubt, share photos of the part and the model number with a parts specialist.
How can I test the part safely before replacing it?
First unplug the appliance or switch off power at the breaker. Visually inspect for burnt connectors, breaks, or obvious damage. Use a multimeter to check continuity and resistance where applicable (consult the service manual for expected values). For electronic components, check for proper voltage at the connector while the appliance is powered (exercise caution—only do this if you’re comfortable and experienced). If a part shows open circuits, shorted windings, or values out of spec, it usually needs replacement.
