Microwave Won't Start? Door Interlock Switch 6600W1K001D – Fix No-Start Fast

If your LG or Kenmore microwave powers on but won't run when you close the door and press Start, a failed door interlock switch is the most likely cause. In most LG-built microwaves, the door interlock system uses a series of micro switches that must all close in sequence for the unit to operate. When one fails, the microwave refuses to start — or trips the internal fuse. ⚡ Common failure point in LG-built over-the-range and countertop microwaves. Part 6600W1K001D is the genuine OEM replacement that restores normal door-interlock operation immediately.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

  • ✔ Microwave powers on — display and clock work normally
  • ✔ Door closes and latches fully
  • ✔ Outlet and circuit breaker confirmed OK
  • ✔ Internal fuse is intact (or was blown and replaced)
  • ✔ ONLY problem is microwave will not start when door is closed and Start is pressed

Not sure? Send us your model number — we'll confirm before you order.

🔧 Common Symptoms

  • Microwave won't start — most common, what customers search
  • Pressing Start does nothing after door closes
  • Microwave blows internal fuse repeatedly
  • Unit starts only when door is held at a specific angle
  • Microwave runs with door open (interlock failure)
  • Intermittent no-start — works sometimes, fails others

✔ If these symptoms match, this is the most likely failed component in the door interlock system.

✔ In most cases, replacing this door interlock switch restores normal operation immediately.

📦 Part Details

  • Part Number: 6600W1K001D
  • Type: Door interlock micro switch assembly — normally open (NO) primary switch
  • Replaces: OEM direct-fit door interlock switch — supersedes 6600W1K001A, 6600W1K001B (no modification required)
  • Brands: LG, Kenmore
⚠️ Recommended While Repairing:
Check and replace the internal ceramic fuse at the same time — a failed interlock switch almost always blows it. Replacing both in one visit saves a second service call.

⚙️ Installation

Skill Level: MODERATE — 30–45 minutes. Unplug the microwave and discharge the high-voltage capacitor before touching any internal components. Remove the outer cabinet, locate the door switch assembly behind the latch board, swap the failed switch, and reassemble. Caution: Per safety regulations, door interlock alignment and shielding integrity must be verified after replacement — a qualified technician should perform this step.

💡 Pro Tip

Replace All Three Switches Together:
LG door interlock systems use a primary, secondary, and monitor switch in series. If one has failed, the others are under the same wear and heat stress. Replacing all three at once costs a fraction of a second call-back and eliminates the most common repeat failure. Ask us about the full switch kit for your model.
