Works a few seconds then the fuse blows. model#JES13845F


Fuse holders sometimes become weak due to heating. If the fuse is not held very tightly by the holder, the fuse will blow because it gets hot, not because the current exceeds the fuse's rating. If this is the case, replacing the fuse holder would be in order. This is not to be confused with the situation where the fuse blows when the door is opened or closed. In that case it's a door switch sequencing issue, or a bad switch.

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.

How do I access fuse in a jmc7000adw? Unit is "dead", want to check fuse first before calling repair person


To check the fuse in the JMC7000adw you first should remove the power cord from the power source. Then remove the screws holding the outside cover of the microwave . The High Voltage circuitry may hold a residual charge that could be lethal so use appropriate care when near the High Voltage circuitry. The fuse holder is a plastic inline clamshell type that must be opened carefully with the fingers or pried open. The fuse holder is located above the micro-switches near the internal light socket. The fuse plugs into contacts soldered onto wires so carefully pull the contacts off each end of the fuse being careful not to get cut if the fuse breaks. Sometimes the blown fuse might come apart so you will need to force the fuse ends out of the contact using a small screwdriver or other small instrument that will fit into the end of the metal fuse contacts. After replacing the fuse with the appropriate size I suggest you might wish to see if the fuse blows again before reinstalling the cover. Most likely the fuse blows because of an overload in the circuitry or a short in the safety micro switches as noted in other posted solutions. These micro switches seem to be underrated for the current they may be carrying and the contacts will weld themselves together or intermittently stick together causing the fuse to blow as noted in my previous posting.

GE microwave oven model#JVM1441BH04 when you close door on switch activates and oven comes on. Only goes off when door is opened.


HELLO.

the problem your are experiencing with your microwave oven is a failed interlock switch.
Be careful when closing your microwave door. Slamming the door too hard is one of the main reasons that the interlock switch is damaged.

Slamming the microwave door shut can easily blow the microwave fuse, but they can also blow due to problems with the interlock switches.
A microwave oven will not function until the fuse is replaced.

Instruction on how to replace fuse on microwave.

1. Unplug the microwave from the electrical outlet to prevent electrocution. Place the microwave in a well-lit area to be able to locate the fuse.

2. Use a screwdriver to remove the outer cabinet of the microwave, and follow the power cord to the fuse. The fuse is located 2 to 3 inches within the microwave and is attached to the power board.

3. Observe the fuse to determine if it is blown. Blown glass fuses will produce burn marks on nearby surfaces, or the internal fuse wire will be black and melted, while ceramic fuses show no outward appearance of being blown.

4. Determine if a ceramic fuse is blown by testing it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is not blown. Other readings on the ohmmeter show that your fuse is blown.

5. Replace the blown fuse by popping it out of its holder, and snapping a new fuse in its place. Tighten the fuse clips by squeezing them together with your fingers.

6. Replace the outer cabinet of the microwave, and plug the microwave back into the electrical outlet. Test the microwave to see if it's working properly.

I have a blown internal fuse on my JennAir M170b microwave. The fuse holder says 250V, 15A fuse, but the fuse that was in there is a 125V, 15A fuse. The micro plugs into a normal 110V circuit. Which type...


Hi,

The information on the fuse is the maximum rating. The holder may not match the rating.

The 'A' is the very important part of the size. You will need a 15 Amp fuse. The best fuse to use is 'ceramic'. You can find them at Radio Shack in the back of the store there are drawers with electrical parts.

15 Amp ceramic

Possible fuse -- no power


Replacing a fuse Locate your fuse. Most microwave fuses look like the one pictured to the left. They are usually an inch or two long. Each end is metallic and the center is either ceramic or glass.
To get to the fuse, remove the outer cabinet of the unit, which is usually held in place with a few screws. Once the outer cabinet is removed, follow the power cord into the unit. It will take you to the fuse holder, where the fuse sits. The fuse holder is located two or three inches into the unit, and may be attached to a power board.
Decide if your fuse is blown. A blown glass fuse will produce flash burn marks on nearby surfaces, or it will be completely black on the inside. The internal fuse wire (filament) will be melted and blackened. Ceramic fuses give no outward signs of having blown. To determine if a ceramic fuse is blown, test it with an ohmmeter. If the ohmmeter reads zero ohms, your fuse is fine. A reading of infinite ohms means your fuse is blown.
Replace the blown fuse. Pop it out of its holder and snap in a new one. You can squeeze the fuse clips together with your fingers in order to tighten their grip. Replace the unit's outer cabinet, plug it back in, and test to see if it is running properly. DO NOT run the microwave with nothing in it.
NOTE: Fuses do not usually blow on their own. A fuse may blow because of problems with the interlock switches or with high voltage circuitry. It is also possible, though rare, that a power surge will cause a fuse to blow.

Fuse


I'm confused! You say you cannot read? OR, You cannot read the fuse. Remember on fuses, voltage rating is as important as amps. What is the make and model? is there a diagram of the wiring inside? get someone to read the amps (fuse) to you.
Note: Most common is a 15amp (for M/W Oven). Can be purchased at most Hardware Stores.
CAUTION!! Do not over-rate or under-rate the fuse. If it blows with the correct fuse in it Do Not put in a higher amperage fuse!! Can everyone say FIRE!!
