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.

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.

The TCOs you need to be concerned usually with have all black or white wires only. Please reply with photos of your interior if you have questions.

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.

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.

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.

SOURCE: no power to microwave all ready checked fuse box

the circuitry has probably gone bad, try plugging it into a different electrical outlet, but if that doesnt work, its probably dead. and it will be cheaper for you to replace than have serviced, unless its still under a warranty

No power, no lights, no clock. Nothing works on my Samsung over the range microwave model SMH17138


Your microwave may be plugged into a regular receptacle which is on a circuit breaker often in a cupboard above the range.Check around to see if anything else is not working. Check your circuit breaker box for a breaker that needs resetting. If you see one out of line with the others turn it off and then back on. Good luck..

My Kenmore elite microwave model 401.88523011 has lost power. The electrical outlet still has power to it. Is there an internal fuse or circuit breaker that may be causing the power outage?


Your microwave has an internal fuse. Usually 10 to 20 amp. You can pick some up at home depot or radio shack. Make sure you get the same amps and volts as the original fuse. Will be printed on your microwave some where usually. And if its one that is part of a double oven deal make sure that you check you're circuit breakers for the kitchen. Good luck.

If there are no fuses or circuit breakers, the unit could be down and out. Check you power box for any tripped breakers.

How come my over the range microwave does not turn on at all??


Check internal fuse. If it's ok, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. Diagnostics and repair might be quite complicates so better you take it to a repair service. You have some interesting Youtube video tutorials to repair a microwave

My GE JVM1750DM blew an internal breaker or fuse when I attempted to remount a lamp lighting the stove top; it had fallen out of its mount. Where is the internal reset or breaker located, and how do


There are fuses inside the unit. No internal breaker. A lot of the time that damages the main circuit board too. Blowing the trace that supplies the power to the bulb off of the board. will probably need a new baord, or someone to repair that one.

Microwave MH7130XEB-2 stopped working while cooking. Is now dead. Check plug and breaker box, they are ok. Is it an internal fuse? If so what part # do I need?


Hello :

Problem with the power transformer or the power PCB . Or it could be just a fuse . You need to check first . If it's the fuse , then that will be easy to solve , you need only to replace it with new one . But if the problem is with the transformer or with the PCB , you need to take your microwave to the service .

You could check for manual here :

Emerson microwave mw8773sl has no power, no lights


Make sure that a lamp will work in the outlet powering the microwave. If ok, remove the case (with the plug pulled), and look for a tripped breaker or blown fuse. If found, check for a shorted high voltage diode in the magnetron power supply. It may also have a shorted stirrer bearing located above or beside the cavity where the microwaves come into it. The stirrer is a metal fan-like device that scatters the microwaves to get more even heating and has a plastic bearing that arcs internally causing a microwave short. Replace the stirrer unit.
If no fuse or breaker troubles, look for faulty or loose micro-switches around the door latch mechanism.

Has no power


If your microwave oven doesn't seem to work at all, check these: Fuses 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. Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.
thanks
