Frigidaire Microwave Fuse - 5304509451

Restore protected microwave power when the correct fuse has failed with this genuine OEM Frigidaire Microwave Fuse - 5304509451. This line fuse protects compatible microwave circuits and is replaced when the original fuse has opened after the cause of failure has been diagnosed.

5304509451 is listed as a 125-volt, 20-amp line fuse. Source listings show use in select Frigidaire, Kenmore/Sears, Electrolux, microwave/oven combo, and range applications. Because microwave high-voltage components can retain lethal charge, this part should be installed only with proper safety procedures.

Compatibility: Fits select Frigidaire, Kenmore/Sears, Electrolux, and related microwave, microwave/oven combo, and range models where the parts diagram calls for 5304509451.

Fitment Families: Microwave line-fuse family. Exact fit depends on amperage, voltage, fuse size, holder style, access location, and the appliance model. Do not substitute a different amperage.

This part commonly cross-references or replaces previous/service part numbers including 5304488359, 5304464087, AP6230606.

Fitment / What To Verify: Verify full model number, 20 amp / 125 volt rating, fuse body size, fuse holder style, and why the fuse failed. A blown fuse may indicate a door-switch, monitor-switch, high-voltage, shorted component, or wiring issue.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Microwave will not turn on, unit is completely dead, fuse opens repeatedly, or power is lost after door or start operation.
• Visible/Sensory Cues: Open fuse on continuity test, darkened fuse body, heat marks at the fuse holder, loose fuse clip, or repeated fuse failure after replacement.

Pro Tip: Never bypass a fuse or install a higher-amp fuse. If the replacement fuse opens again, stop and diagnose the underlying electrical fault before further use.
