If you're trying to say that the fuse blows as soon as you press the "start" pad to begin cooking, then you have as shorting high voltage capacitor.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

In case it's still helpful, I'll inject a little sanity into the replies.

If the fuse blows as soon as you hit Start, it's probably a shorted high-voltage capacitor. That's usually economical to repair.

If the fuse blows a few seconds after you hit Start, it's probably a shorting high-voltage transformer. That's usually not economical to repair.

It's not radiation (non-ionizing RF by the way) that's the hazard, it's the voltages.

A microwave can be dead for many reasons.

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

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 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.

It sounds like a shorted high voltage capacitor, a fairly cheap fix. But if it's good, I would suspect the high voltage transformer.

Here are some links you or a friend can use for test help, but read the safety warnings first:

SOURCE: My Ge SpaceMaker XL1800 Microwave Oven won't power on any more.

1.Check power outlet for working.
2.If it is than you have broken fuse inside the m/w.
3. To change the fuse you have to disconnect the power to m/w, take the upper grill off, take the screw on top of control panel, lift the control panel up and removed. The 20 Am fuse located behind this panel.

SOURCE: Microwave oven blowing 20 amp ceramic fuse

Chances are if the varistor fails, it fails drastically causing a short circuit across the supply. It will sit across the supply (it will look like a thick ceramic capacitor) and you can check for continuity after isolating that at one end. If it shows low resistance (it should show almost open circuit with a Digital meter), replace it.

It need not be the culprit. If you are familiar working with High voltage circuits ( they are lethal inside a microwave ovens as the current capability is high here), you can discharge the doubler capacitor and isolate the high voltage diode to check for shorts in the HT area.

Put something to heatup after pushing start made standard startup noise then abruptly stopped working even electronics....breaker fine and receptacle working....does this unit have a fuse??


Almost all microwaves have internal fuses. Counter top micros need to remove outer case and fuse should be near where power cord enters the microwave, Fuse looks like old style glass car fuses but is white or gray ceramic. Can't look at it to tell if its bad. Need tester. Over the range (wall Micros) usually have the fuse directly behind the control panel which you will need to drop down away from the body. Same type fuse as stated before. 15 or 20 amp should be stamped on metal edge. Purchase at Radio Shack or a parts store---or some Hardware stores.

The power light no longer turns on, despite it being plugged in. What may be the problem? A fuse?


Yes, it can be a fuse (usually a 20-amp fuse), or it can be a thermal cutoff device (called a TCO or thermostat) that is usually located above the cooking cavity (under the outer panel).

Has no power,


see the next steps: God bless your use the common sense, NOT feared.
No Lights or Power, Unit seems Dead First check is the main fuse of the unit. On countertop units, you will need to take the shell off. The fuse will be close to where the cord comes through into the unit. OTR units, this main fuse is usually behind the control panel or possibly behind the vent. Usually the fuse is obvious if blown, otherwise test with an OHM meter, if open, replace fuse.
Some brands will also have a thermal cut-off fuse in the incoming voltage line to the control board. Older Maytags and Samsungs have this fuse in it. This thermostat looking fuse is usually above the oven cavity somewhere under the outside shell. Sometimes you can get to it through the vent of OTR models. Test with an OHM meter, replace if open.

Cooks Model 2115 microwave oven will not power on when connected to the 110v outlet. Can this be a fuse problem? If so, where is the fuse located?


Yes, is probably the fuse. I have fixed several microwaves with this problem and the fuse is almost always located just inside where the power cord enters the unit. Just remove the skin (usually screws on the back and BOTTOM also) test the fuse with a micro meter. If no contenuity, replace with same size, type and rated fuse. Most microwaves are 20amp fuse.

it is behind the control panel.to access that remove the top grill by removing two screws on the top or in the fron of grill.then u should see see a screw on the top of control panel holding it.remove that screw and u should be able to remove the control panel.fuse will be behind the panel.it is not mounted on the panel but in the cavity behind it.
