Microwave Oven fuse keep blowing.
HTML-код
- Опубликовано: 4 дек 2019
- Every time I put a new fuse on the microwave oven to run it, it will run for a 2 seconds and blow the fuse again, so I did some testing on all the parts and find out that the high voltage capacitor is bad, so I replace the bad capacitor and put on a new fuse and run it, for a few seconds and it work great again.
When testing, never let the microwave run empty. There should always be a glass of water inside to absorb the heat. Letting it run empty causes "bouncing" waves, which can lead to malfunction.
Good point. That's why I only run it for 12 seconds. every time I testing a microwave oven to know if it heating. I does only run it for 12 seconds. I know what will happen if it run for more then 12 seconds. thanks for the heads up.
True
Great video! I replaced the fuse and it blew right away. A bad capacitor was exactly my problem. Thanks!
no problem, glad my video help you, pass it on and help someone who might need a helping hand.
Hi! Mr. Fix It 360. Just wanted you to know I watch all your videos and it was very helpful to me as a repair man myself. Thanks again for making good videos that help me a lot to do all my repair.
Excellent repair!
Thanks. I have so many videos to make when I get some time on my hands.
Follow this guide. Solved my problem by replacing the capacitor n fuse. Thanks Bro. Superb. From Msia
no problem bro.
This is so much helpful 👍 because I have same issue with my oven and I can't understand whats going on thank you Soo much broo love from pak
Glad I can help bro. pass on the skills or the video to help someone in need.
blessing my Trini brother good job on this video.
Very good technical instruction
your welcome.
Straight "Trini". Just subscribed.
Thanks for the ideas
Very good video!helps a lot.
Thanks. Don't forget to share with friends and family who might need some help.
I can't wait for you to release more wonderful videos again.
Is he going to do it?
Very useful idea sir ,thanks
You are welcome!
@@mr.fixit3604 My GE microwave is blowing fuse and sparks at outlet and blows fuse every time new fuse is put in? what could this be?
@@kellysmith2755 It sound like a capacitor or magnetron problem. but most of the time it does be a capacitor problem. you wouldn't unless you run some test to find out what is the problem.
thanks this worked for me, greetings froma Argentina
Thanks a lot I had changed capacitor and fuse it's working good
Good job my friend
Thanks my friend.
I know this is old but it would be nice to have seen just how you diagnosed that it WAS the capacitor and ruled out other problems like the magnetron itself.
well with 13 years of microwave repair. it become so easy for me to repair microwave with doing so little diagnosed as skills and knowledge develop. most of the time is the capacitor or magnetron go bad.
@@mr.fixit3604 How do you check the magnetron? Check with a multimeter ? How do you rule out faulty magnetron?
@@dennischarles68 Hi good night. You looking continuity from thermal to thermal. Then from one thermal to the magnetron body you shouldn't get any continuity. If you get continuity then them magnetron is faulty.

Thank you fixed my microwave
no problem glad my video help you.
Thanks very much my microwave is working again
Your welcome. I made that video for you all. Don't forget to share with friends and family who might need some help.
Thanks for let us know
No problem. thanks for watching my videos. I hope you learned a lot and have a better understanding of microwave oven.
Absolutely right on dot , thanks a lot
thanks.

What makes the transformer to heat up fast & smoke? Pulling lots of amps the first transformer has burned
Sometimes the transformer can get weak or over running the microwave for 20-30 minutes.
I'm so sorry I take so long to reply. But don't worry when I get time I'll try and answer your questions.
Thanks for watching all my videos. and thanks for all your support.
My fuse blows when i open door. Is my door switch faulty?
@@letmethinkv sound like the switch going bad or it already bad. you will have to check all the switches and replace the bad one.
Thank you.
your welcome,
so nice sir.
Thanks. I try my best to help someone who might have microwave problems.
@@mr.fixit3604 ,thanks followed your tutorial and now its working
@@kagwanjastanley4196 ok cool. glad my tutorial helped you. I made those videos to help people who need with there appliance. share videos to friends and family it could help them.
Good day Sir, can you advise why my microwave oven has fault, the fuse is blowing when door closed and run the power. I already checked the capacitor, diode, transformer, Magnetron, all door switches, and PC card also good but keep on blow the fuse. Even when disconnect the transformer and magnetron.
Micro switch bad.
Good work I have same problem I changed switch but fuse still blown now make sure it's capacitor problem right?
Very good video that is the same thing that is happening to my microwave. Same brand also. Can you tell me where can I get the part to buy and how much for it please
I don't know the price of hand. but if you go online you can see the price. check amazon or ebay.
Hi their. Can you tell me where can I get the capacitor to buy if this video is from Trinidad. I check a few parts place but no luck. Can you help me please. Thank you in advance.
If you not getting it at the general store, you can get it online amazon or ebay.
@@mr.fixit3604 thank you I may have to buy it on line because I am not getting it no where here
I have a similar problem sir,i tried to change capacitor(prebious puffed up and shorted) but i could only get 1.05 mfd instead of 0.98 mfd,STILL FUSE BLOWS, what could be other reason
1.05 is still good.
So the fuse still blows. well it could be a magnetron problem or a switch problem. you wouldn't know unless you run some test to find the problem.
I changed capacitor and diode and fuse still continues to blow. What other to check because all switches are good, magnetron, and transformer test good. I’m lost now, help me out Pleasee! 😖😖
The circuit board must be have a short or something grounding off.
Thanks for the tips o fixing the blown fuse. It was clear and direct.
I fixed a microwave and I discovered it was the capacitor that was bad. So I replaced it. When I wanted to test it the transformer exploded I was shocked.
Pls can you explain why this happened m
Well I can't understand or explain why a transformer exploded. In all my 13 years of microwave repair I never come across a transformer exploded. but I come across a few transformer burned out. I would like to come across a exploded transformer just to find the cause and answer. but for now be safe dude.
My microwave fuse which was blown is 5 kV 550 mA but now it is not available in market, can I replace it with 5 kV 750 mA
Yes you can.
Top man
thanks man. are you Trini by chance ?
nice
Your welcome. I made that video for you all. Don't forget to share with friends and family who might need some help.
What are the other reasons for the blowing fuse, can it be the transformer or magentron?
Transformer
If the fuse from transformer is always blow means transformer have a problem. But he show the fuse from capacitor
It can be the Magnetron or a simple switch on the circuit board. it hardy ever be the transformer.
@@mr.fixit3604 yeah but the magnetron is easy to test, and so is the transformer (also dies very frequently too, specially when the secondary shorts, but that wont burn the fuse). and i dont see how could it be a switch since this fuse is not between them
how did you know it was the capacitor?
I will give you a pass this time because you are a Trini just like me but next just don't guess troubleshoot to component level check the capacitor for short, check diode for short let people see how you arrive at your conclusion.
He is not guessing,it is called experience .I guess people can go to proper course to get deeper knowledge .
How to check whether the capacitor and diode faulty or not... Please explain
Where can I get capacitor in Trinidad
Hi
Main Fuse burn , after replacing 3 times again and again burn what's exact problem
did you run some test on the parts. run test on the capacitor magnetron switches diode.
All brand microwave same problem to fix it?
No. some other brands of microwave is like a pain it the neck. it have some cheap microwave oven that the first thing to go bad is the circuit board. but then it have some expensive microwave oven with the same problem the circuit board gone bad. one day when I get time I'll make a video on how to repair a circuit board on a microwave oven. thanks for watching my videos. I hope you learned a lot.
Yes please i need on control broad..
Thank you ser may oven same pro
burning the fuse with adjacent with plug?
Run Test on the capacitor and magnetron and diode.
A s soon as I plug in Microwave it blows the fuse, what is the reason? (switches are good)
It can be the magnetron or capacitor or circuit board.
Sir can I use 5kv 0.8 amp of fuse instead of 5kv 0.65 amp
Normal a microwave Carry 15amp or 20amp fuse. Check with the manual book to find the correct amp rating fuse to use.
Thanks so much that's my problem by the way are you trini
Is it a slow blow fuse or a fast blow fuse
It's a normal Ceramic Fuse. I can't remember if it's a 15 Amp or 20 Amp fuse. in my 10 years in microwave oven repair I don't think I come across any slow blowing or fast blowing fuse. I don't think microwave oven come with slow or fast blowing fuse.
@@mr.fixit3604 Thank you.
I HV the same brand changed the magnetron worked for a while den the fuse keeps blowing
Run Test on the capacitor and magnetron and diode. the problem is one out of 3 or 2 out of 3.
I see a spark/burning and blast sound near HV capacitor on wire where fuse is connected, when I start the oven to heat... Any suggestion how to fix and what to check?
sound like the capacitor and diode need to be replace.
Does microwave capacitor have polarity ?
No polarity on high voltage capacitor.
What do you mean by disharge the capacitor? 😮
Wats the average cost of that capacitor?
It's depends on which country you from. But it's cheaper to but a capacitor then to buy a microwave oven always.
$12 more or less
Where are you located
I subscribe your channel❤
Sorry for the late replied. you see I don't get any of your messages I don't get any notification from youtube
Sir new sub can you make a video repair of a turbo broiler because i have one which is the connection has been disconnected i have no idea of what turbo broiler wiring diagram i have no formal trainning in electrical school pls help me sir tnx
As soon as I get my hands on one to repair I'll post it up.
What to do
Run some test. but first watch the video again as a step by step guide.
Does it means it must be the capacitor that caused the fuse to blowed?
lol It's the capacitor it doesn't matter how I said it. thank you.
@@mr.fixit3604 I changed the capacitor n the small black about 1 inches black thing but don knownthe name still the fuse blowed.
@@tanpengjoo7205 it could be a faulty magnetron. Check the magnetron.
@@tanpengjoo7205 you meant the diode lol. should've tested the magnetron first though
Pity you didn't show us the fault on the capacitor you removed.
Sorry dude. My capacitor tester not working at that time. I buy a new capacitor tester late last year.
The HV Capacitor should have been discharged BEFORE you removed the wiring from it not afterwards. The way you did this is Dangerous.
What's the safest way to discharge? Can you safely use a big pair of needlenose pliers as shown?
Amar micro oven capacitor Laga shabd
I met two microwaves which keeps blowing fuse Because of... fall of
light bulb inside? wtf it looks like light bulb during time unscrew
itself and fall off inside. than touch metal part to magnetron and keeps
blowing fuses. after picking it up and screw again it works fine. so if
your light goes off it might be lose light bulb. BTW in microwaves i
work with light bulb is secure by lite tape to not unscrew. wtf?
If the light bulb blow or break the microwave will work but there will not have no light lighting.
What if it's not heating?
Check the magnetron , capacitor ,diode,fully gate closed with all limit switch will be on normally closed position, check tranformer also , if every thing is gud then problem is in control broad.if am i right...thanks brother
You have to run test on the megnetron, transformer, capacitor diode, micro switches and fuse.
How much uf
0.82 uf. next time watch the video and you will know the value of the capacitor.
Heating fuse keep blowing
Sound like a Capacitor problem. you wouldn't know unless you run test on all the main parts.
It is nice introduction, but video so dark.
Mr fix it I want to contct you cause I wanna buy parts
you not the only one wants to contact me, thousands, I'm a very busy person with a private life, I'm a all rounder person, in a while I'll be posting up some electrical videos.
SIR, I HAVE GE BRAND MICROWAVE AND IT IS COMPLETE DEAD THOUGH PROVIDING POWER SUPPLY. I HAVE CHECKED ALL PARTS WITH MULTI METER KEEPING ON CONTINUOUS MODE, ITS OK OPEN MANATRON,ITS OK, DOOE SWITCH, ITS OK. WHERE THE FAULT LIES COULD NOT FIGURE IT OUT. PLEASE GUIDE THROUGH YOUR EXPERTISE AND THANKS
well if all the parts check ok, well then there is nothing leaf to do then to buy a new microwave. remember you can't fix all the microwave all the time, some times I come across some microwave that can't be fix. I spend hours trying to fix it and in the end it can't be fix. that's life.
I have lg microwave oven
LG microwave is one of the best products out there.
where is capasitor
no capacitor then your microwave must be are inverter microwave.
It's the large metal stuff on the bottom right. You can't miss it .
