Microwave repair requires extreme caution, fifty-fifty if you are just replacing 1 fuse. Microwaves use much higher voltage than other common appliances, and can crusade serious injury or decease if handled incorrectly. But people experienced in electric repair should attempt this.

1

Evaluate your electrical experience. Even when unplugged, a microwave contains high-voltage capacitors that can crusade serious injury or decease. Although fuse replacement is like shooting fish in a barrel (but not necessarily safe), a blown fuse is often a sign of other electrical issues which may be difficult for a layman to handle. If y'all are not experienced with electrical repair, hire a professional.
2
Take safety precautions. Microwaves are among the nearly unsafe household items to repair. Protect yourself before you brainstorm:
- Remove all jewelry and watches, which could snag on components and behave electricity. Magnetic microwave components may damage some watches.
- Wear safety soled shoes and consider wearing insulated gloves.
- Accept someone nearby to call emergency services if necessary.
- Take care non to touch any metal parts within the microwave, particularly circuit boards and capacitors.^[one]

three

Unplug the microwave. If your microwave is mounted nether a chiffonier, the power cord is usually threaded through the overhead cabinet.
iv
Remove the vent grille. The vent grille is usually located at the top of the microwave, fastened with a couple screws on the upper surface. Later on removing the screws, unhook the plastic tabs by sliding the grille (usually left or upward). Fix it aside. Label all screws with their original location.
- On some models, you'll need to open up the microwave door to access the grille.^[two]
- Some models take the grille on the back of the machine. You lot may not need to remove this rear grille to remove the other panels, only there could notwithstanding be a fuse behind information technology.^[3]
five

Detach the control console. Look for screws on the side of the command panel revealed by the grille removal. Besides remove any screws on the upper surface of the panel. Lift the control console and pull forwards to detach it.^[four] Prop information technology up in a stable position without unplugging any wires.
6

Remove exterior panels if necessary. You at present have admission to some but non all of the microwave's interior. You may look for an electrical problem now, or unscrew and remove the remaining panels for total admission.

1
Wait several minutes (recommended). The capacitor can hold a potentially lethal charge even when the microwave is unplugged. Although the accuse is supposed to drain when the microwave is turned off, this may accept several minutes. Fifty-fifty after waiting, do non assume the capacitor is prophylactic. This safe feature may have failed, or may not exist present in your model.^[5]
- Always confirm the microwave is unplugged before you go on.
2
Locate the capacitor. In most models, the capacitor is a metal cylinder with 2 or iii electrical terminals. If you cannot identify the capacitor, hire a professional repairman. Never disassemble interior components to expect for it.
- Do not touch whatsoever role of the inverter board that contains the capacitors. The aluminum heat sink, windings, and asphyxiate coil are all high voltage.^[vi]
3

Choose a screwdriver with an electrically insulated handle. You may also wish to wear insulated gloves, particularly if you are not sure what voltage the handle is rated for. Voltages upward to 5000 volts may be present.^[7]
4

Prune a resistor to the screwdriver tip. Prune a 100K Ω resistor rated for 25 watts or higher to the blade of your screwdriver. This will slow the charge per unit of discharge, preventing impairment to your screwdriver or microwave components.^[8]
5

Clip the other cease to the metal chassis. Attach the other stop of the resistor to the metal chassis of the capacitor, using an alligator clip. Insulated gloves are recommended for this pace to avoid brushing against the terminals of the capacitor.
6
Touch the screwdriver tip to one terminal of the capacitor. Hold it there for a few seconds while the accuse drains.
- Co-ordinate to the GE service manual for a JES series microwave, you may belch at the magnetron filament final instead.^[9]
7
Repeat with the other concluding. Confirm the prune is still grounded, then touch the screwdriver tip to the other terminal.
- Repeat with the 3rd terminal if nowadays.
8
Check for charge. Withdraw the screwdriver and unclip the resistor. Touch the screwdriver tip to i terminal, then slide it to the other. If in that location is a popping noise or spark, the capacitor has not discharged properly.^[10] The voltage should now be gone, only bleed each concluding to ground again just in instance.
- Never test for voltage using a standard multimeter. They are not fabricated to handle the extreme voltage found in microwaves.

Cheque for obvious problems. A blown fuse is usually a sign of an electrical fault. Perform a visual inspection for scorch marks, dead insects or other debris causing a short circuit, and broken or leaking components. If any of these are present, you will probable need to replace or repair additional parts besides the fuse.
- In that location are many possible causes for a blown fuse, and these are not covered in this guide. I mutual crusade is a broken door interlock switch, which may crave replacing several door components or realigning the door.^[11]
- WARNING: Practice not touch on or detach an unidentified component. If you lot cannot place the broken office or practise not know how to handle loftier-voltage equipment safely, hire a professional repairman.
ii
Locate the fuses. Your microwave may have two types of fuse. The line fuses are normally familiar ceramic tubes, near 1¼ inches (three cm) long.^[12] The thermal cutoff fuses are typically squat black cylinders with two prongs on the same side. Their verbal location depends on your model, but check behind the control panel.^[thirteen]
- If you are having problem, consult the wiring diagram printed on the inside comprehend of the microwave (or occasionally on the underside or back of the exterior panels).
- Some fuses may be hidden by other components.^[14] Only remove these components if you are familiar with their function and know how to handle them safely.
3

Remove the fuses safely. Pop out the fuses with a fuse puller or the tip of a screwdriver with a well-insulated handle. To remove thermal fuses, pull the wires off the prongs. Make a note of where each fuse came from.
4
Examination the fuses with a multimeter . Almost microwave fuses exercise not look whatsoever different after they are blown. To exam them, set your multimeter dial to the continuity examination if nowadays, with the symbol ) ) ) . Otherwise, set it to the lowest Ohm setting.^[xv] Test the fuse resistance:
- Touch the ii probes together. Yous should hear a tone if the multimeter is fix to continuity. If gear up to measure resistance, the multimeter should read 0 Ohms. (Analog multimeters may need scale.)
- Touch the two probes to opposite ends of the fuse.
- If the multimeter reads 0 Ohms or you hear a continuity tone, the fuse is working. If the multimeter measures resistance or displays "OL" for overload, or if in that location is no continuity tone, the fuse is blown.
5
Replace the fuse with an identical component. The fuse must be exactly the same size and take the same amperage rating as the original. This information should be displayed on the fuse, although you may need a magnifying drinking glass to read it.
- Pop the new fuse dorsum in with the fuse puller or insulated gloves.
- Buy a couple spare fuses. If at that place is an underlying electrical problem, the new fuse could blow besides.
half-dozen
Reassemble the microwave. Replace all panels and screws in the reverse lodge you removed them. Cheque all tabs effectually the edge of panels to brand sure they fit deeply in their slots, without pinching any wires. Improper reassembly could cause radiation to leak out of the microwave during operation. Make sure all screws are in their original position, as some may exist responsible for grounding the embrace.^[16]
- Never plug in or run the microwave until it is fully assembled. Place something inside the microwave earlier testing to avoid overheating.^[17]
