SOURCE: Blowing fuse problems

The door latch switches, and monitor switch assembly needs adjusting. With the door open the two latch switches should be normally open,and the monitor switch closed. Opposite way when door is closed. MAKE sure oven is unplugged before testing

first you gotta detach the button plate ( the thing with all the buttons) using a flathead screwdriver .Keep pushing it is stuburn. It will pop back in when you are done. the fuse is behind that. just take it out and put the new one in.

SOURCE: stopped work when open microwave door no power now

I finally was able to fix similar problem. The "primary" door switch (top switch) had a burned contact inside the switch body, as well as burned surrounding plastic. It would no longer "click" and tended to stay in "closed" position. [The switch is a "normally open" design (NO).] When this occurs and the door is opened, the "monitor" switch causes the fuse to blow out. GE wants $50 for this part. However, I was able to find a universal design of microswitch at Fry's Electronics. It had the same rating (15 amp at 250 volts), same body size, both NO and NC terminals, but with a lever arm which I had to remove by opening the case. Cost was $2.47 + tax. (PRICELESS!). So far so good. I also had to buy a set of Torx driver bits for tamperproof screws to be able to remove the oven cover. (The hole in the end of the bit goes over the tamperproof pin of the screw).
I also viewed a YouTube video which was helpful at http://www.youtube.com/watch?v=YsWTCnACqdY

SOURCE: Problem with the Bosch HME9760

Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

SOURCE: ive got a d90d25eslr111-b1 micro combi,i poached an egg ani ie exploded in the micro,it blew the electic and went off,if i swith it on its ok,as soon as i shut the door it fuses the electric. why plea

see this causes and fix it. God bless you
If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostats.
If the microwave runs for a few seconds and stops the thermoprotector may have tripped. This is a safety device to prevent the microwave from overheating. It can be tested for continuity to see if it's blown.
If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.
If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the dishwasher display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.
If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.
If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.
If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently.

R-9H84B. It just stopped working.Went to use it and nothing , thought it was unplugged. Repair man replaced the 20 amp fuse and it immediately blew. He said it was the transformer.Is it transformer?


It could be the transformer. Is it generating any smoke? They usually burn up because of shorted windings.

If the fuse blew, however, when the door was opened or closed, then you have a bad door switch.

If the unit heats, and the fuse blew after a few minutes, then you could have a weak fuse holder.

How can I obtain a service manual for KitchenAid microwave KHMS1850S,need wiring diagram to interlock switches.


Pulled up a schematic on this will try and help the first pic looks as though you removed the secondary switch the bottom one if so that is the wrong switch it should be a normally open switch that one is normally closed this switch goes up top on the other side of the primary switch the one with 3 terminals, look at the second pic the switch with 3 terminals that red wire in the wrong spot the skinny orange goes there the switch I just told you to put up top the red goes to one terminal the white and brown middle form the 3 terminal goes to the other terminal, the blue/white and blue go to the bottom switch this is a normally open switch if you don't know how to read a switch look at the switch look at com follow the line to where it stops if it is NO=normally open, NC=normally closed your primary switch is in the right spot you want the switch next to it to be NC and the bottom switch NO it blew the 20 amp fuse once you correct the switches and wiring and put in a new fuse if you have no power then it blew past the fuse and burnt out the filter board happens some times about 60 bucks let me know if this helps

Microwave blows fuses


A short likely in the wiring for the light or at the safety switch embedded on the side where the door closes----be careful as a 20 amp fuse takes something major to take out.
(for it to blow)

This might be best left to a qualified service person.

Dead, replaced fuse and it blew again.


The fuse is connected directly in series with the monitor switch. If it senses one of the door switches bad it will blow the fuse, this is there as an added safety to make sure the oven will not work without the door closed.

There are usually three and sometimes four door switches just inside and to the left of the control panel that are activated when the door interlocks with them. One of the switches is most likely bad. Typically it is the primary interlock which is on top. It can be checked with an ohmmeter, usually you can see it broken as the plunger will not go down or come up like the others.

Blows fuse


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead several 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.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/diode.html
(if it is NOT shorted or burned looking, it's probably fine)

Fuse or circuit breaker blew


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 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.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

No Lights just turned off


Chances are the magnetron overheated and the blew the thermal cutout (TCO or thermal fuse), thus protecting the magnetron.

Bacon has a fairly low moisture level and when can cause overheating if there's no water load in the oven.

When I opened the microwave door after use. The power went out as if a fuse blew. I checked my home fuse and I also plugged the unit into another outlet.
