The WG04F00666 is the individual micro switch that sits inside the GE dishwasher door latch assembly. It's the electrical component that signals the control board when the door is fully closed — without a working switch, the dishwasher won't start or will stop mid-cycle. If your door latch mechanism is physically intact but the dishwasher still won't run, this micro switch is the likely culprit. Often paired with the WG04F10037 door switch assembly.

The micro switch is a small but critical electrical component mounted inside the door latch housing. When the door closes and the latch engages, it physically depresses the micro switch actuator, completing the circuit that tells the control board the door is secure. A failed micro switch — from worn contacts, moisture intrusion, or mechanical fatigue — breaks this circuit and prevents any cycle from starting.

✓ Common Symptoms Fixed

This micro switch directly resolves: dishwasher won't start despite having power, control panel lights up but no cycle initiates, cycle stops unexpectedly mid-wash, and door latch clicks closed but dishwasher still won't run.

✓ Frequently Asked Questions

How do I know if it's the micro switch and not the whole latch assembly? If the door latch clicks and holds the door closed but the dishwasher still won't start, the micro switch has likely failed while the latch mechanism is still good. Test with a multimeter — no continuity when the switch is depressed means the switch has failed. See our guide: Dishwasher Won't Start – Door Latch & Switch Problems.

Should I replace just the switch or the whole assembly? If the latch housing is intact and undamaged, replacing just the micro switch is the more economical repair. If the housing is cracked or the latch mechanism is worn, the complete WG04F10037 assembly is the better choice.

Is the XPart switch the same quality as OEM? The XPart WG04F00666XP is engineered to the same electrical specification as the OEM switch. It is a direct drop-in replacement.

Can I install this myself? Yes — this is a beginner-friendly repair. Access the latch assembly through the inner door panel and swap the switch. Total time: 20–30 minutes. Contact us if you need model-specific guidance.
