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.)

Replace fuse Kenmore 40188523011

If you know that a fuse is open, you need to find out why it went out before replacing it. There are typically three fuses in any given microwave oven. Line or monitor fuse, cavity temp fuse and magnetron temp fuse.

Replace microwave coil

If your microwave is totally dead, it may be the line-fuse that is the problem. Leave the microwave unplugged for a day (it may contain a capacitor that could have residual electricity that could give you a nasty jolt). Undo the screws that hold the front outgoing-vent grill.
You may be able to see the fuse through the secondary grill (they don't want you touching the circuit-board, but you may have to). The line-fuse may be attached to the circuit-board.
If it is, undo the secondary grill screws, and bend the tabs that hold the secondary grill to remove the secondary grill.
Pull-out the fuse from the fuse-holder, and get an ohm-meter to test. If the ohm-meter reads near-infinite ohms across the fuse, get a magnifier to read what is on the end of the fuse.
The imprint on the old fuse should mention a rated voltage, and amperage.
Then go to Radio Shack, and buy an equivalent replacement fuse.
Replace the line-fuse with a new one, plug the microwave back in, and see if the display comes-alive, and if it does, set the clock ad try to heat a cup of water. If the cup of water heats, replace the secondary-grill (careful, that capacitor is now in-play) and screws, replace the outlet-vent-grill and screws -- you may not even have to take the microwave off of the wall !

Kenmore elite model #665.61683101, has no power, plug works but microwave has no display, is there a fuse in this model?

There is a line fuse for this oven. Remove the cabinet and the fuse should be close to the line cord. Replacement fuses should be found at your local appliance supply house.

PEB1590sm1ss light bulb change. 1) Cannot find the light bulb location (believe upper right) 2) How do you change the bulb? Broke down the unit until it I ran into a screw type that cannot work with.

Even though this post is older I will state how to replace your oven lamp. First you have to remove the outer casing a couple of philips head screws and 2 torx head screws. Next in the middle you will see the oven lamp you have bend down to see it is hooked up to a wire harness. What I did was take the screw out first holding the oven lamp assembly then wiggle the assembly out of where it is held. Now disconnect the harness and there you go. Replace lamp and reverse the instructions and now you are set to go. No reason to call a GE repairman total time est. 15 to 20 minutes.

Nothing working - just quit. Power source ok.

There are 3 fuses in that microwave. I had a similar issue. The one that I had to replace was the little ceramic fuse that is in line after the big fuse which is connected to the main line.
I couldn't find the ceramic fuse but I replaced it was a glass one about a year ago and it has been working since then. The fuse if located on the right front panel.

It could easily be a bad line fuse and/or line filter. To access you will need to unplug the unit and remove the outside case. Inside the unit, where the A/C power cord comes in, there should be a small circuit card (part #237068) located somewhere with a fuse mounted on it. This is your input line filter board with line fuse. Replace the fuse, first and see if this fixes your problem. This is a 20amp appliance fuse that you can purchase at any hardware store. Make sure you place the cover back on the unit BEFORE you plug it in. It is not safe to have this area of the microwave exposed with power applied. High potentials in the 4,000 volt range are present! If the fuse does not correct your problem, the circuit card runs about $26.00. Good luck and hope this fixes your problem.
