Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board. Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron. Check this link to know how a microwave works:

http://www.espares.co.uk/advice/microwave/a/5/1443/how-a-microwave-oven-works.html

So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Check the wave guide covers, if food had deposited
then it must be checked or replaced. See link:
http://www.espares.co.uk/advice/microwave/a/5/1146/how-to-replace-a-microwave-guide-cover.html

Now keeping clear of the microwave, switch on; use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely

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.

SOURCE: microwave smells of electrical fire

The magnetron inside the microwave is starting to short out to ground. This happens after use there are small minute cracks on the body of the magnetron and those small cracks are big enough for 15,000 volts and up to 30,000 volts to leak through and arc to ground. It is not a small short but a big one. Replace the magnetron before it burns holes inside your microwave. Replacing the magnetron if you can find it locally or through the internet is pretty straightforward. Unplug the microwave and take the cover off about 6 screws. On the same side as the control panel and right behind it you will find the microwave on top. It is held in place with only three to four big screws. It will have about 4 wires with terminals on them that plug into a couple of places one being the large capacitor that stores all the voltage and discharges it through the magnetron. Take the terminals off and I always recommend with some needle nose pliers with insulated handles. There is nothing to unsolder and to solder. Its like replacing the battery in your car or the electronic module. Take care and good luck.

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.

SOURCE: GE model JE2160BF03 no power. Blown fuse.

They are put out when something metal is put inside and cooked for a few min. They are also put out with power surge. It protects your mag tube. Plus they just go bad sometimes. Could be a number of reasons but these are the most common.

My old GE Spacemaker II microwave (JEM21K001) died. I was using it, heard a little pop, and it lost all power. Is this something simple to fix like replacing a fuse or is it bulk trash at this point?


HELLO.

take on these steps to solve the problem.

Check if there is electric power on wall outlet.

If the microwave plug has fuse,check if it has not burnt.if these are okay there is need to take the last step.

things needed
1.Screwdriver
2.Ohmmeter
3.New fuse

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.

Thanks.

Our microwave is a GE Spacemaker, Model # JVM1630WB004, mfg. in Mar, 2001. Just today it suddenly decided not to function other than the light in the oven coming on when activated, etc. It does not cook...


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.

How to open GE microwave and check fuse?


In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

No, not with the same mounting hardware. You have to replace everything. I recommend Panasonic first if you can find it in a hanging hood model, Whirlpool second. Make sure you also install a 2000 joule or larger surge protector. Good Luck, Appliance Specialists

GE Sensor Microwave JES1855 died


Mine went dead after about 6 months. I had problems with my breakers and I found out that it was the microwave that blew all of them. I also found out that this perticular microwave is a fire hazard and should be recalled. It has caused me alot of headache. The breakers in my house are brand new and they are put out by GE also. It caused me to loose the food in my freezer, I did not know my freezer had lost power. It would cause my entire lights to go off and then they would come back on. I have checked around and I found out that the power cord on the back of the unit is very loose. I had a person to come in and look at it, he thinks its the power cord.
