XPMTC-180 Microwave Thermal Cut-Off Fuse 180℃ (356°F) Normally Closed

XPMTC-180 Microwave Thermal Cut-Off Fuse 180℃ (356°F) – Normally Closed – Universal Microwave Safety Cutoff

Product Description

Protect your microwave from extreme overheating with the XPMTC-180 Microwave Thermal Cut-Off Fuse 180℃ (356°F), Normally Closed. This high-temperature safety device is designed to remain closed (conductive) during normal operation and open permanently when internal temperatures exceed 180℃, immediately cutting power to prevent serious damage or fire risk. A tripped thermal cut-off can cause the microwave to lose power or stop heating. Replacing it with the correctly rated NC fuse restores safe and reliable operation.

Compatibility

This normally closed microwave thermal cut-off fuse is compatible with many GE, Whirlpool, Samsung, LG, Frigidaire, Panasonic, Sharp, and Kenmore microwave ovens that require a 180℃ (356°F) NC thermal cutoff.

Commonly used near the magnetron, high-heat zones, or cavity protection points.

Always verify temperature rating and contact type before ordering.

🔍 What’s the Difference Between NC and NO Thermal Cut-Offs?

• Normally Closed (NC): Circuit is closed during normal operation and opens permanently when the rated temperature is reached.
  👉 Most microwave thermal cut-offs are NC.

• Normally Open (NO): Circuit is open during normal operation and closes only when overheated (used in limited designs).

⚠️ Installing the wrong type (NC vs NO) may cause the microwave not to run or fail to protect against overheating.

🛠️ Installation Notes

Tools Needed: Phillips screwdriver, insulated pliers

⚠️ Safety First:
Unplug the microwave before servicing. Microwaves contain high-voltage components—allow capacitors to discharge before handling internal parts.

Basic Steps:

1. Disconnect microwave power.

2. Remove the outer cabinet or access panel.

3. Locate the thermal cut-off near the magnetron or high-heat area.

4. Disconnect wiring and remove the failed fuse.

5. Install the new XPMTC-180 (NC) thermal cut-off in the same position.

6. Reassemble the microwave and restore power.

7. Test operation.

⏱️ Time Required: 15–25 minutes
