Microwave Completely Dead? Power Cord W10708076 — Fix No-Power & Intermittent Shutdowns Fast
A microwave that won’t power on at all — no display, no light, no response — often has nothing wrong with it except a damaged power cord. In most Whirlpool-built microwaves, the AC power cord is the first point of failure when the unit is moved, reinstalled, or subjected to heat damage near the cord entry point. A frayed, cracked, or internally broken cord cuts power entirely or causes intermittent shutdowns that are easy to misdiagnose as a control board failure. ⚡ One of the most overlooked and easiest fixes in Whirlpool-built microwaves. Part W10708076 is the genuine OEM replacement that restores clean, reliable AC power delivery to the unit.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Outlet is confirmed live (tested with another device)
- ✔ Microwave shows no display, no light, and no response when plugged in
- ✔ Visible damage, kinking, or scorching on the existing power cord
- ✔ ONLY problem is complete loss of power with no internal fault codes

🔧 Common Symptoms
- Microwave completely dead — no display, no light, no fan
- Intermittent power loss that resolves when cord is repositioned
- Burning smell near the cord entry point at the back of the unit
- Visible fraying, cracking, or heat damage on the cord jacket
- Microwave trips the breaker or GFCI outlet repeatedly
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this power cord restores full operation immediately.

While the microwave is pulled out for cord replacement, inspect the door switches and fuse. A damaged power cord that caused a surge may have blown the thermal fuse — replacing the cord without checking the fuse can result in a unit that still won’t power on after the repair.
⚙️ Installation
Skill Level: Easy — 10–15 minutes. Disconnect power before servicing. For OTR models, the cord typically routes through the back panel — remove the rear access cover, disconnect the old cord from the terminal block, route the new W10708076 through the strain relief, connect to the terminal block (match wire colours), and secure the strain relief before reinstalling the cover. Test before remounting the unit.
✓ Compatible Models

💡 Pro Tip
A power cord that failed due to a surge or short may have taken out the thermal fuse at the same time. The fuse is a $5–10 part and takes 5 minutes to test with a multimeter. If it’s blown, the microwave won’t power on even with a new cord — catching it now saves a second disassembly and a frustrated customer callback.
