Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• No display, interior light, or control response
• Microwave stops operating after an electrical surge or overload
• Replacement fuse opens again shortly after installation, indicating an unresolved electrical fault rather than a confirmed fuse-only failure

Check Before Replacing

• Disconnect electrical power at the breaker or unplug the appliance before any inspection.
• Verify the appliance documentation and existing fuse markings specify a 20 amp, 250 volt time-delay fuse before replacement.
• With power disconnected, visually inspect the fuse and fuse holder for an open fuse, discoloration, heat damage, or loose connections.
• Do not bypass the fuse, install a higher-rated fuse, or repeatedly replace a fuse that opens immediately; microwave high-voltage components can retain a dangerous charge and require qualified service.
