Whirlpool WP4375321 Microwave Line Fuse – Genuine OEM Replacement Part

The Whirlpool WP4375321 Microwave Line Fuse is a genuine OEM (Original Equipment Manufacturer) replacement part designed to protect your microwave from electrical overloads and power surges. Available at Appliance Kingdom, this high-quality fuse is engineered to meet Whirlpool’s exact specifications for safety, reliability, and performance. It is compatible with select Whirlpool, KitchenAid, Maytag, Amana, and other Whirlpool-family microwave models. Always verify your appliance model number to ensure proper compatibility.

Function & Importance

The microwave line fuse plays a critical safety role by interrupting electrical flow when excessive current is detected. This protects essential microwave components such as the control board, transformer, and magnetron from permanent damage. When functioning correctly, the WP4375321 fuse ensures safe operation and prevents costly electrical failures. A blown or faulty fuse will stop power from reaching the microwave, preventing the unit from turning on.

Common Symptoms That Indicate Replacement

You may need to replace the WP4375321 microwave line fuse if you notice any of the following issues:

  • Microwave completely dead with no display or interior light

  • Microwave loses power immediately after starting

  • Unit stops working after a power surge or door slams shut

  • Circuit breaker trips repeatedly when microwave is used

  • Burning smell or visible damage near the fuse housing

These symptoms are common indicators that the microwave power fuse has blown and should be replaced to restore safe operation.
