SOURCE: Panasonic Microwave

The fuse is usually a 250V 15 or 20 AMP and can be found at any hardware store. As for those screws...those are special tamper proof screws made to keep the average consumer out of dangerous appliances. There's about 4000 volts inside a microwave oven when it is energized. That's why the manufacturers don't want the average Joe tampering with it. You can, however, buy the tool required to get inside the unit for a reasonable price. I think it's less than $30 and I know Craftsman makes it. The line fuse is located on or near the input line filter board. Just follow the input power cord and you will find it. Just keep in mind, that if the fuse is blown, it usually blows for a reason. You may have other problems. Let me know if this helps you.

SOURCE: Panasonic Microwave Fuse Replacement

Is it like this?
ae5b501.jpg If so, there are several ways to loosen them:

Some folks just use a hammer to tap and loosen the screw, then a "star", t-type, or small flathead screwdriver can be used to remove the screw.

Sometimes the screws are tough, so you may only be able to just bend the post slightly with a punch, then a small flat blade will "grab" enough to turn the screw. Pliers on the handle will help, too.

Another creative solution is to use a hacksaw or a Dremel tool to carefully cut a slot in the head so a flatblade will fit it, as shown in the photo below:

The Panasonic NN-S960WA (may be identical) has the fuse at back, right, on top, & inside the cover. The screws are tamper proof screws. You can create a slot in the heads (2 screws) with a hacksaw blade and open with a flat blade screw driver. Don't forget to unplug the unit first.

SOURCE: ge spacemaker microwave jvm1630bkc

it is just behind the front top grill on the right. The plastic grill that goes accross the entire top of the front of the unit. Then behind it on the right is a small power board that has the ceramic fuse on it.
remove 2 srews from top of microwave that hold the top of this plastic grill in place.
Then slide the grill to the left or right (I don't remember which way). Now the grill will come out.

The fuse is usually the secondary issue. Most often, it is the cavity TCO that goes out. This is the thermo-coupler that breaks the main power circuit if the inside of the mocrowave gets over 100 degrees C. requires taking the unit down and taking the cover off.

SOURCE: My LG microwave went completely dead. I is only 3

under the outer cover,its either a 10-15-or 20 amp ceramic safety fuse avail at most hardware stores, the amp rating is on the side of the fuse, if the new one blows then either the H.V. diode/capacitor or the magnetron can be suspects

Replace thermal fuse for LG microwave LMV1813ST


If too much current passes through the microwave circuitry, the line fuse will blow. If the line fuse blows, the microwave won't start. To determine if the line fuse is at fault, use a multimeter to test it for continuity. If the fuse does not have continuity, replace it. In addition, you should investigate and resolve the problem that caused the fuse to blow. If you don't resolve the underlying issue, the new fuse will blow too. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the line fuse.)

My LG microwave oven 3850w4a043b is working but not heating up?


Check the microwave fuse. It is in a plastic fuse casing on a wire. The fuse is about 1/8 dia x 2inch. Be sure to replace it with exactly the same rating.

LG Microwave ran empty for 20 minutes


I recommend you have a service man come in because it is more than a fuse, the keypad control board will need to be checked along with the rest of the system.

Blown fuse 10 amp LG microwave oven model ms2127c it blown while im cooking a popcorn. what shall i do?


You can get a replacement fuse from almost anywhere ranging from Ebay to an authorised LG repair agent, but please remember a blown fuse can simply be the symptom of a larger problem, so my advice is to buy two, replace it, if it works then you have a spare, but if upon replacing the fuse,it blows again straight away, your microwave may have a more serious problem. PLEASE READ UP ON THE DANGERS OF A HIGH VOLTAGE CAPACITOR AND ALSO HOIW TO DISCHARGE ONE AS THEY CAN HOLD A LETHAL AMOUNT OF CHARGE AND CAN CAUSE FATAL INJUFRIES INCLUDING DEATH.

Our microwave keeps blowing fueses. Model MS305SS Why would this be?


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

Help with repair for LG 2055ST


Check the internal fuse. Unplug it, unscrew and take off the cover, the fuse should be easily found in the back by the power cord. I tlooks like a regular fuse but is white instead of clear glass because microwave fuses are special. You'll have to measure it with a meter as a result and be sure to replace it with the same kind. (try finding them at radio shack) Hopefully there isn't something more serious also.
