Yes there is most of the time. A new fuse can be obtained from radio shack. Most ovens use a small ceramic cartridge fuse ABC 15 or ABC 20. Please note though that this fuse usually blows because one of the small microswitches in the door circuit is bad (overheated and is burning up inside) or has operated out of sequence with the other several switches. Newer microwaves have one big switch assembly that needs to be replaced when the fuse blows. Make sure the door fully closes when replacing a switch. Be very careful with microwaves. There is very high voltage inside that could severely shock you!

Unit went dead. No fan, display, light, oven. Is there an internal fuse or reset?

There is an internal fuse. Be careful high voltages present even if the microwave is unpluged.

Good luck

My LG over the range microwave and vent stopped working. The outlet it's plugged into is fine.

it may be an internal fuse that popped. try a lamp or something in the outlet. if that's ok, it's probably a fuse inside the microwave.

The microwave does not react what so ever. Checked the fuse and its fine, what could be the problem? please help

Is there power at the outlet? You say you checked the fuse ... is that the one inside the machine? Is the outlet protected by a GFI (reset for a GFI is on the GFI)? A GFI looks like a ordinary outlet but is very sensitive to electrical irregularities. Your circuit breaker may be on or your power panel fuse may be fine and the fuse inside your oven may be fine. If the GFI is popped, you have no power.

Try some other electrical device in the outlet. Does it work? Try an extension cord from a known hot outlet?

Beyond these tips, you may need professional help with this.

Oven won't work. Fuse is fine and so is outlet.

if the unit has no internal fuse that has failed, check/replace the capacitor that connects to the magnatron

No power to microwave, changed fuse but still nothing!

There is an internal fuse and internal TCOs (thermal cutouts / thermostats) any of which can interrupt the power to the unit.

Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.
