- This applianceassist... video describes the three types of appliance circuits, the three main elements of an appliance circuit, and the three problems that can occur within an appliance circuit to cause your washer, dryer, refrigerator, or any other appliance to not work properly. I hope you like it! Let me know what you think and what I can do to better help you!
For proper appliance repair training I recommend training.freds...
10 years and we are still using this video in science class, anyone end up over here because of online learning?
Thank you for this! It made my day : )

I didn't know Ray Romano knew so much about appliance repair. Thanks Ray!
Good video but I'm a bit confused also b/c I too thought switch should be on hot side.
the hot to the switch no the light. neutral to light not switch.
0:12 “OH NOO” 😂😂😂🤣🤣🤣🤣😭😭 why is that so funny to me?
Your diagram is wrong. The switch should be on the hot leg, not the neutral leg. Neutral should never be broken for safety.
That may be true, however, in major appliances the relay is fairly commonly placed on the neutral side of the circuit. so that cannot be assumed when working on appliances.... I used a home light switch in the illustration because it would be difficult to animate a control relay. Thanks for pointing that out though!
Dave B I
Lmao noticed that right away the bulb will have continued load
NO DISASSEMBLE JOHNNY 5!
This just in: "Johnny Five *is* alive!"
Hey appliance guy! Terry Peterman, The Internet Electrician here. I have a Bosch front load washing machine that I'd love to pick your brain over. I'll check your website to see if you have a way of asking questions.
The thumbnail alone is wrong. You want to break the hot wire at the switch, not the neutral. Another thing is you want to ground your entire circuit and not just the source of power, run a ground to the switch and if applicable to the light. If you break neutral and someome switches the light or application off it is still hot. which means if someone comes along to do work on the light (and they dont turn off the breaker) it is still hot. Which means if they touch the hot side and they are grounded its gonna bite them. ALWAYS BREAK HOT AT THE SWITCH! ALWAYS!
great video on explaining how circuits work,types of problems ,etc...but the most important thing is that your showing a switch on a neutral instead of the hot.this is a serious user safety concern.i have seen it many times on old and new house wiring.you can confuse a person by showing in your diagram that they will want to put the switch on the white wire which will always keep the device hot at all times.this is a non no.someone might accidentally touch the screw socket portion of the device and get shocked.always put a switch on the hot side of any device for safety.so someone won't assume that the socket,receptacle or appliance is off and then go touching it when the panel breaker or fuse is out or off.
I was wondering if this was going to be brought up....good job!!
In the circuit the control system (the switch) should have been on the LIVE (hot) wire and NOT on the return Neutral or dead wire. In the case of this circuit the appliance would be "live" if the neutral (dead) wire open circuited. This would be a dangerous situation on that type of fault.
Thank you for bringing up this point! We have AC and DC circuits in USA appliances. This is mainly about basic circuit structure, function, and failure. I didn't want to get to heavy into the the aspects of current flow this one. This was also a learning experience for me messing with a new animation program :) Thanks for the comment!
IM so confused
You NEVER switch a circuit on the neutral side (i.e., white wire); that is DANGEROUS!
Can I ask why?
@@arturzych138 If you switch (for example, a light fixture) on the neutral side instead of the hot side, you run the risk of someone being electrocuted while changing a lightbulb, because the socket will still be live, even while the light switch is off. The average Joe expects there to be no voltage while the switch is off, and may believe that it's safe to stick his finger into the socket. DON'T DO IT!
@@karlscheel3500 Wouldn't it still be live regardless?
@@arturzych138 No, if wired correctly, with the black wire interrupted by the switch, there would be zero voltage at the socket with the switch in the off position. Although the neutral wire remains connected in this scenario, it's always at zero volts, so there's no danger from touching the neutral connection even if you are simultaneously touching a grounded object with the other hand (e.g., the metal chassis of the lamp fixture itself). The danger would exist if you had the wiring backwards; in this scenario, if you were to touch the bottom of the lamp socket with one hand (which would still be live), and simultaneously touch a grounded object with the other. The current would then flow through your body (including your heart), and potentially kill you.
Why is the current going through the bulb 💡 before to go to the switch on your demos of how simple circuits are constructed. Isn’t it the other way around ?
Thank You! I'm trying to learn some new production skills, I'm glad to hear you like it.
Just updated the CC on this video so hopefully translated languages will make a little more sense!
+applianceassistant Great video i juts graduated as a Electronic Tech. and you explain some stuff that so jac!@# professors that come from engineering backgrounds explain it in theory instead of in a practical know how.
+applianceassistant I have spent months researching into circuits and found a great website at Gregs Electro Blog (google it if you are interested)
My English is not that good but with the cc on i cud understand everything. thank you.
U boy or girl
the least resistance to the ground statement is not true. It's okay very common misconception. everything else, great job
Thanks for the question! Just today I was working on a whirlpool dryer, model number CAE2743BQ0. And the door switch was on the neutral side of the motor.
When E is used in place of V it means "Electromotive Force" V for "Voltage" would have probably been a better choice for the video... Thanks for the question!
I dont mean to be so off topic but does anybody know a way to log back into an Instagram account..?
I was stupid lost the login password. I would appreciate any tricks you can give me.
@Onyx Jasper instablaster ;)
@Levi Demetrius thanks for your reply. I found the site on google and im waiting for the hacking stuff now.
I see it takes a while so I will get back to you later with my results.
@Levi Demetrius it worked and I finally got access to my account again. I'm so happy:D
Thanks so much, you saved my account!
@Onyx Jasper Happy to help =)
Why is your diagram drawn with switch in the neutral? these are surely now placed in the line conductor always, by wiring code?
+sbusweb In major appliances the switch or relay is often placed on the neutral side of a circuit. With home wiring definitely. And I did use a light switch for illustration. The nice part about a switch being placed on the neutral side of a circuit is less component strain.
Alternating Current doesn’t care where a switch or relay is connected on either side of the load. Forget the code and look at the physics.
Never "forget the code" sigh
Witch software that is you used
or any software avail?
+Umair Ali I used Motion for this one. Great app! Thanks for the interest and question!
hopefully this will help in my science class, lol, i have 2 days to finish a house and EVERY room stopped working. I'm 99% positive I have a shorted circuit, and I'll have to go through all my wiring, but now atleast I know what I should do. Thanks for the help
What is that oh no sound from about 11 seconds in? Thank you in advance.
Mark Nguyen It was an apple loop through soundtrack pro.
Huh, I could've sworn it was Spongebob. Thanks for the info. Oh, and for the video!
Now that you mention in I can hear that : )
I am so happy to find your channel!
Your switch is wrong side of your lamp for the way your flow is.
You are correct. However, in the application of appliances, the switch or relay can be placed on the neutral side of the load, such as a dryer door switch or washer lid switch.
@@applianceassistant very rare and you have a switched light which should never have the neutral switched.Even if it is neutral switched your switch is on wrong side.
As an electrician, i will have to give you a dislike! If you're helping people to fix it them selves, you're messing with my money making, and if you mess with my money, you messing with my life! :D
This needs taken down it is dangerous others have mentioned it but you never use a neutral as a switch leg. Using white wires in this video as you switch leg is WRONG!!!
Check out your dryer wiring diagram. You'll see neutral switching. It's very uncommon but given the appliance background and nature of the video it can be forgiven .
black wire should be going to the switch first, then to the bulb , and out as a neutral.
Thank you very much sir it's a awesome tutoring i like it's very much.
VERY good video !!! - Thanks for taking the time to explain in such a clear way. I will check out the other videos and your site.
Thanks for the comment! Glad you liked it!
don't switch the neutral please
A really good video .The problem is the switch should be on the black wire which is the hot conductor. You never switch the grounded conductor/white wire (slang neutral )
In major appliances in it not uncommon to have the control switch on the neutral side of the circuit. Definitely good to clarify for home wiring though! Thanks for the comment!
That switch supposed to go on the hot side not on neutral.
Switches are sometimes on the neutral side of a circuit in appliances. E.g. Dryer door switch.
@@applianceassistant I'm not 100% sure but I feel like neutral switching is mainly in dc circuits
Thank you for showing us how NOT TO wire a lamp with a Switch circuit.... NEVER Switch the neutral. WTF
Thanks for the explanation, very good!
Sounds like a serious power surge like a near lightning hit... You can fix the trace but it is likely that there would be other damage in the board. Bummer!
Well DONE !!!! Very funny!
Thanks! I try to make them entertaining...
There is one small problem with your video ,the switch that is shone is on the wrong conductor , A switch should always be on the black or hot conductor never on the white or neutral conductor . But who knows with appliance manufactures they have their own rules.
You are absolutely right! I have spent many hours scratching my head over a few control related issues... but for the most part (with appliances anyway) its generally pretty simple. Thanks for the post!
Why the switch is located on the neutral wire?
The bulb is located the Live wire..
The switch connects the neutral wires to complete the circuit..
Isnt its dangerous if accidently touches metal plate in the bulb holder while changing the bulbs even the switch is turned OFF..😅
For wiring a house that would be dangerous... However, I used these simple components to show how circuits work. In appliances, such as dryers, switches are often placed on the neutral side of a load, eg. the door switch. So it's best to not assume anything when troubleshooting. There is also the situation of reversed polarity where the white wire becomes "hot". Honestly if I could, I would go back and fix that aspect of this video but RUclips doesn't allow editing of a published video. Thanks for the comment!
This video is a failure and should be corrected or removed. You never switch the neutral wire in a circuit, always the hot wire. This video could kill you.
I have no clue what this means. lol
Electric current DOES NOT "take the path of least resistance to ground." That is a myth and a dangerous teaching. The equipment grounding on electrical systems is not to provide a route for over-current faults in the circuit(s) to discharge in the earth--this is a popular misconception. The equipment grounds in a system provide an efficient route back to the source of power, which, in most cases, is the transformer. The electrical current always moves in a circle from and to the source of current. So in the event of a ground/circuit fault, the equipment grounds being bonded to the neutral at the first load distribution center of a system, the fault clears by returning the current to the source. That is per the NEC. Ground rods are to protect the system from DC over-current surges of power such as lightning strikes that have their origin outside the system.
Interesting! You are correct about an appliance's ground contacts returning current to the neutral connection. However, either way you look at it the end result within an appliance circuit is a dead short that is void of resistance to current on it's path back to the local transformer, instead of the grounding rod of your home. Thank you for your clarification.
I've been an electrician for 16 years and have heard the "fastest path to ground" foolishness even from other electricians who should know better. It's a"rule of thumb" that will get you a sore thumb, because it mistakenly implies ground is the origin of electricity and that ground is integral to circuits. Like Paulus said, electricity wants to go back to where it came from. Electricity DOES NOT come from ground. Electricity comes from the power source. "Ground" is an INTENTIONALLY ALTERNATE path back to the source . We intentionally bond the earth and metal parts with the potential to carry current as alternate paths back to the source. While resistance exists naturally in any conductor, grounding conductors are low resistance in reference to the normal circuit loads.
Also the video has the switch on the grounded conductor (white wire), not to mention the switch was on the load side of the lights!!!
We only switch the ungrounded conductor per NEC. And if you're going to control the load, the line has to go to the controller (switch) first. A little research, and this video would be fine. Right now it's enough misinformation in the animation alone for me to warn people not to do it yourself based on this video.
Thank you for taking so much time to clarify the definitions. This video is not about home wiring it's about appliance troubleshooting and repair. Within home appliances the switch or control relay is often opening the neutral side of the circuit. Which I think is more important to focus on because a switch is not necessarily disconnecting a component from line voltage! Also when troubleshooting appliance problems you can measure voltage at a component to ground and not have operation due to a failed relay or switch which is located after the load in the circuit. This point about the difference between neutral and ground is good because measuring voltage to a ground connection or to an appliance cabinet is a good way to waste a lot of time. Because as you stated ground is not the intended path, it is a safety precaution. Thanks for your comment.
Another thing most people don't understand is that it is necessary bond the ground wire to metal junction boxes and metal cases of equipment. Regardless of the actual grounding rod placed in the earth being attached to the ground wire, without equipment or electrical boxes being properly bonded, the breaker probably or definitely won't trip in the case of a line to ground fault. Also, among other reasons, the grounding rods are placed in the earth to have a reference of 0 Volts and to maintain that all grounding paths in the electrical system stay at 0 Volts.
Kris Klekosky Good job and well said! Please visit my band page @ facebook.com/aerophi for real music. Thanks and take care friend!
My goal is to identify the functions of the devices in a given circuit diagram?
Or spoken more general.
How can I lean this general skill?
When do I see a random circuit diagram in all kinds of electronic fields that I can recognize the devices and their functions?
What is the best strategy to acquire this skill?
Do you know good information recourses specially designated to acquire this skill?
I do not want to handcraft things on my own and I do not want to study at a university to acquire a bachelor's degree in electrotechnology.
I just want to be able to read and being able to understand more or less the circuit diagram.
Thank you in advance
That's a difficult question. Personally I learned over time while working in the appliance repair field. I would imagine self study of basic circuit component symbols and their functions would give you a solid understanding that would be sufficient for most situations. It seems intimidating, but there really are not that many components that are regularly used. I made a page years ago that outlines the basics applianceassistant.com/appliance-repair/electricity-and-testing/how-electrical-parts-work/
I hope that helps get you started!
I 100% agree! Thanks for the comment!
Who are you talking to?
great concepts but not offering much in the way of application examples...1/2-way useful.
thanks for the upload anyway.
+Hip-Hop Homework Thank you for the constructive criticism! That kind of specific, actionable opinion is extremely helpful!
Charles Yingst You're very welcome!! I'm glad to be able to help your future contribution efforts have a more meaningful impact.
#collaborationiselevation
Cheers!
Thanks for the comment and repair tip! What was the appliance and model number you were working on?
very appreciated sir and very helpful
Nice video, I appreciate the explanation!
I cannot find an answer to this anywhere. In the UK we have Line (230v) and Neutral (0v) and Earth (0v). I understand that the neutral is linked to earth so there is no difference in potential. However, what happens in you were to disconnect neutral from earth? You would then have 2 x 230v live connectors, the potential difference would be 0v but yet the circuit will still work??. I have an isolation transformer which has 2x 115v secondaries, if you wire them in series you will get 230v and both connections will be live. What actually happens when I ground one side of the transformer, where does the voltage from the once live connector go?? Will I then have a 230v connector and a 0v instead of 2x 115v? I want to know what actually happens to the voltage of a live connector when it is grounded
Your diagram is incorrect and is confusing to the viewers. You see this in the comments. You acknowledge this in a your own reply 1 year ago. Your diagram should be changed or the video should be taken down.
No it wasn't!!! I understood everything taught and I am NOT an electrician or appliance repairman. BUT.. I have fixed two washers, dryer, and a refrigerator! And they are STILL RUNNING
JAMES BOZO-KOKOVICH you need to settle down brother!
This was awesome. Many thanks to you AA.com....
I have a problem with light bulbs burning out in a certain area of the house. I have to replace light bulbs every 3 months. When they go dead they blink every 30 to 40 seconds by themselves. When I turn the switch on and off the flicker as well. Please help. Thank you!!
sabe more? most devices need special tools to diassembly, like the washing machine. its not a job for everyone.
It's difficult to make appliance repair fun or entertaining so I try to sneak it in where I can : )
you are awesome thank YOU!
So I replaced a switch light because it was doing a buzzing sound every time it switches to the ON position. So seems that the new switch fixed that buzzing problem; but now some lights won’t turn on, some others do.
Electricity does not take path of least resistance, it takes all path weighted with their conductance (1/R). If that would be the case, you wouldn't be able to operate multiple electrical devices in parallel at all.
'
oh mooo...
stop watch this video at 020...
dont have to show this video about currencys papers on the hand...
dont need it...
not important
Ok, confused, the diagram shows power going to the bulb, so if switch is off there is still power going to bulb. Resulting in a shock or arc flash...am I wrong ?
If anyone is interested in electronics the greatest results that i've ever had was with the Gregs Electro Blog (i found it on google) without a doubt the no.1 course that I've followed.
Snowden? Is that you?
lol....i think you're circuit is wrong ....please check and correct it ..
I have that same torch soldering iron :)
Too bad that modern appliances are designed to fail beyond practical repair.
We still have all home appliances from 1989, and they've super robust parts. Of course we've had to repair some probelm once every 5 years, but nothing serious. I love when something goes wrong with these thing and I can take it apart. 95% of the time I'm able to find the problem and solve it. Fight against the modern planned obsolescence!
Great Video Man! Thanks! I subscribe immediately I believe I will learn a lot from your vids.
your great i,m 15 and love electronics.You have increade this
same here. i am 15 and i love to tinker with electronics. but by now u must be 23...
Sir if I use old glass bulb so he glow fine but if I can replace led bulb he cannot glow what is problem. I can check led bulb of series board he is fine.
In refrigerator
Honestly I’m not sure. I would suppose it may be a voltage supply problem... perhaps if it was a dimmable 120VAC LED bulb it would work.
@slappyd1ck Thanks for the comment I'm glad you enjoyed it!
@rituparno100 Thank you for your comment! I'm glad you enjoyed it! I love electronics as well, and I hope you stick with what you love! There is always a need for people who understand how all these gadgets that we use work!
Yes you are correct! I had to use a really heavy duty one in this animation for illustration purposes : ) They don't make em' like that any more!
I laughed at the components making noises, ahh- eww-eeee-ect, and the finger touching the wire with fire on the finger tip.
Elegant. Thanks
You can replace PCB traces by soldering wires to them, if the traces are large enough.
I've done it few times when surge has blew up the traces on some old machines that have plenty of room to solder a wire as a replacement.
So I put a bobby pin in an wall outlit and it popped and made sparks should I be worried
Thanks! That was a fun one to produce... took a while to make but learned a lot of new animation tricks : )
@ApplianceAdvice Thanks!
@ShadeCanopy Thank You!
Just wanted to say your videos are impressive, you have put sometime into them and they look good! Keep up the solid work friend!
online college brought me here, and dang this was a great find!
thats good but if the white wire is neutral,where switch is wrong..
Just curious can you place the switch before the light bulb?
It's a great mobile tool! Thanks for the comment!
what happen when the wire ring in the house both live and neutral have power and when you plug in a radio or anything good the power goes off. what could be the reason behind it
Yo need call electrician... NOW!
can a balbu become open circuit?
voltatage x ampere will give you the energy value in watts
W = V*R = (I*R)*I = (I*I)*R. So what? ... Non sequitur.
Oops! I mean W = V*I = (I*R)*I = (I*I)*R
@d4jmo Thanks! I like this one too :)
Thanks for sharing it with us
The circuit in 6:05 is wrong as for any bulb to work it must have a live and a neutral. The bulbs on the left only have the neutral
Hi Edgaras. Because they are wired in series with the bulbs on the right they would have connection to neutral through the other intact bulbs. Thank you for your comment!
i was tought that u can put black tape on the neutral at the beginning of the load and the switch if white
great video, old but very good none the less.
Thanks for the video - improved my understanding of these concepts. Clearly we as individuals would do further research to understand the topic fully. Shame to see people criticising free/useful knowledge? I guess it's much easier to add a negative comment (excuse the pun!) rather than to make your own educational video! Before anyone adds another lecture; if you think you can do it better, make your own video... #JustSaying
Thanks for the thoughts you have discussed here.
Very easy form to teach the concepts, thanks again.
Help me. I wanted to watch the switch but there was a shot it is in parallel circuit
Extremely helpful; been researching about electricity lately. You have gather all of the key factors in a very short video. Thank you so much. Unfortunately, this video is clearly underrated.
@MrRiffraff1369 Thank You!
applianceassi
thanks for the video!
What is a 'hot wire' and 'hot leg'? I don't know what they mean.
it's a term used for a wire that is "live" or has voltage applied to it.
Controversy Owl I'm no electrician, but from what I've learned, the hot wire is the one not connected to ground at one of the two junction boxes. Appearently it's a grounding thing related to safety. In ac there's hot (line) and neutral, though both conduct electricity... None of the videos I've seen explain how hot and neutral effect actually wiring something, like a motor, light, tv, etc... I know that some things order matters, while others it doesn't matter...
I have understood
