GE WD21X479 Dishwasher Door Switch | Long-Lever Microswitch | 5A 125/250VAC | Genuine OEM | Made in China | New

✅ Genuine OEM | New Factory-Sealed | Part #WD21X479 | 5A 125/250VAC | Compare at $22.99

If your GE or Hotpoint dishwasher won’t start, won’t run a full cycle, or the control board doesn’t recognize the door as closed, the door interlock switch is one of the first components to test. The GE WD21X479 is the genuine OEM long-lever microswitch that detects whether the door is fully latched — and signals the control board that it’s safe to begin the wash cycle. A failed switch means no signal, no cycle. This is the exact part from GE Appliances factory packaging, sourced new through verified liquidation channels.

🛠️ Installation Notes

1. Verify compatibility first: Confirm WD21X479 matches your specific GE or Hotpoint dishwasher model’s parts list before ordering.
2. Disconnect power and water: Turn off the circuit breaker and shut off the water supply before beginning any repair. Never work on a live dishwasher.
3. Remove the dishwasher’s front door panel to access the latch and door switch assembly.
4. Photograph all wire terminal connections on the old switch before disconnecting anything — you’ll need to replicate the wiring exactly on the new unit.
5. Unclip the faulty switch from the housing, transfer all wire terminals to the new WD21X479, and ensure each contact is fully seated.
6. Reinstall the door panel, restore power, and test the door latch cycle before running a full wash.
7. Store in original sealed packaging in a cool, dry place until installation to protect contact terminals from oxidation.
