Yes, there is. If you go to searspartsdirect.com and type in your model number, you will find the fuse listed under the "Interior Parts" heading as item number 14 (part #815174). You can find appliance fuses much cheaper at the local hardware store. Just make sure it is the correct type and rating (refer to the fuse in the appliance for the information - these are usually a 120V 20A fuse). The reason I mention this site is because they provide excellent part drawings and provide part numbers. There should also be a wiring diagram located behind the control panel to assist you in troubleshooting. Please go to my profile and use the "Ask Me" feature if you require further assistance. I hope this helps you.

SOURCE: Sharp Microwave Model R-1830: No power

A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open oven thermal cutout (TCO) on the top of the oven cavity / body or an open thermal fuse on or above the magnetron.

These should read closed (virtually zero) on a continuity check.

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

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

If it went dead or when you plugged it in or opened or closed 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.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

You can usually find exploded views and order parts by entering your model number here at the Sears parts site but the best place to order Sharp parts is Tritronics.

A microwave can be dead for many reasons.

It may be the fuse, which is usually located behind the grille or on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking TCOs or thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If the cavity thermostat needs to be checked or replaced you'll need to pull the oven from the wall, in which case you can download GE owner's manuals and installation instructions here.

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

If it went dead a few 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.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

There should be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

You can usually find helpful exploded view diagrams by entering your full model number here. Once you have the part numbers, though, I would suggest ordering parts here at a much lower cost.

It may be the fuse, which is usually located behind the grille, on the floor of the oven behind the control panel, between the door switches, or on the filter board near where the cord comes into the unit.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking TCOs or thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

So don't let that fool you.

If the cavity thermostat needs to be checked or replaced you'll need to pull the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

I have a GE Profile spacemaker 2.0 microwave and it just quit working on me. Sounded like a fuse popped?? I verified that the electrical outlet was working. Is there a fuse to replace inside the microwave?


Hello. You have isolated the problem.

Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.

Microwave dead even though power works


It sounds like the magnetron overheated and opened the thermal fuse on the magnetron.

This can be caused when the internal cooling fan is not running or by a magnetron that is failing.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the magnetron will be destroyed.

There should be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can also find helpful exploded view diagrams and order parts by entering your full model number here.

The magnetron will have a 5 to 9 year warranty. Your manual will tell you that.

You can download GE owner's manuals and installation instructions here.

If needed, GE may send you a replacement magnetron. GE Customer Service is here.

GE JVM2070 issue


what is the make and model number

Not working model # jvm1339bw 002


Check the main internal fuse. Unplug it, unscrew and take off the cover, the fuse should be easily found in the back by the power cord. It looks 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.
