Thanks, I didn’t look at multisim in depth enough before shooting off this question.
I didn’t take it that way. And as you may recall, I’m a cop, so believe me, I see the lazy in people on a daily basis, and I completely agree with your assessment!
You mentioned that many techs on appliantology are the type that would rather just know the answer. I have noticed that too and I’ve been surprised by that. I’m glad to be learning the way that I am. Also, I joined a couple of closed Facebook groups for appliance repair. I’ve been both in awe of the collective knowledge of the members, and also kind of shocked by people who post things like “ok, I’ve replaced this, that, and this other part; which part should I try next?” Wow, that’s surprising that people who do this for a living are approaching it like that. I agree that the basic electricity and circuit knowledge is essential, just having trouble digesting it. I know I’m not alone; I’ll keep plugging away at it!I think anything like the webinar would help, yes. To be able to watch you go through a diagram of a machine that I’m actually working on would be great. As far as being overwhelmed, I totally agree with you, and I have gone back on many of the modules to review, after finishing them and taking the tests. I find that very helpful. I’m not complaining at all, I think maybe it’s just a combo of a lot of information that is very new to me, and trying to apply that information to real-life scenarios. For example, the Samsung dryer…I know that I took a module about how to look at a PCB and translate what I am looking at, from the schematic. The problem I have, I think, is that it’s new information to me and it doesn’t all stick the first time and I feel a bit lost. I grew up with an electrician father, but that didn’t transfer to me by osmosis, for sure! I’ve never really taken any kind of electrical measurements before, so that is very different for me. It definitely holds my interest, but I just need to find some hands-on instruction. I’ve been working on this end and I think I have something lined up to start fairly soon. Meanwhile, I’ll keep studying!
Thank you,
Sean.Ok, I watched the webinar on the Samsung no heat complaint. It was very helpful to me, but I’m a bit overwhelmed with the info toward the end. I think my problem is trying to apply this to an actual, real world appliance. I feel lost in this and I think I’ll go back and review some of the lessons, such as how to transfer the information from the schematic, to better understand what I’m looking at on the actual appliance. I hope that makes sense.
Thank you, I think I need to go back and review this part of the course.
You can see on the schematic that the heater receives power via a relay on the main board. The door switch supplies Neutral to the board two ways: directly and via the second centrifugal switch contacts on the motor.
No, I couldn’t see that, which is my trouble. I thought I had downloaded the proper information from appliantology, and I will take a look at what you just provided later tonight. Thank you for the help.
The door switch does not connect to the heater and, based on the problem you described, I’m not sure why you’re interested in this… unless you’re troubleshooting a no-heat complaint.
Ok, exactly my question. I was interested in the door switch because of the error code that the dryer showed in diagnostic mode. This is indeed a no-heat complaint. I totally agree with your advice on the ten-step tango here. I started out with that in mind, but had the aformentioned trouble reading the schematic correctly, and jumped to the machine’s self-diagnosis mode. Ugh.https://appliantology.org/files/file/2424-samsung-dv42h-dv45h-dryer-training-manual/
I had watched the video and was able to find and download this tech sheet. This is very new to me, and while I’m really liking the course, I’m having trouble reading the schematic by myself. So as I said above, could you help me in understanding whether the door switch (error code displayed) is connected to the heating element? I just don’t see it. I did test the switch and it showed an open where there should have been a small amount of resistance (less than 1 ohm).
Oh man, at the risk of sounding really stupid, I don’t know what you mean or how to do it. I went to appliantology to try to find the link that I downloaded and I’m not sure how to access my history for the downloaded file.
Well, now a follow-up question along the same lines: I downloaded the tech sheet for DV42H5000EW/A3. This is an electric dryer for the above mentioned friend. I was glad to get a call for some hands-on experience, and looked forward to using what I’ve learned to be able to look at the diagram and try my hand at diagnosing this dryer. Problem is, the diagram, even when expanded, is very difficult to read. I”m curious whether most of the tech sheets are of this quality or it this one unusually bad?
Also, in trying to read the schematic I have a question: I put the machine into self-diagnosis and it showed a code for the door switch. In looking at the schematic, I don’t see how the switch is connected to the heater, which is the “thing that isn’t doing its thing” on this dryer. I’m trying to understand these schematics, but am having some real difficulty here. Would you take a look at this model’s schematic and advise? No rush, but I could use some guidance here.
Thank you.Nevermind, I figured it out!
Ok thank you Scott. I have been doing the reading, but I did somehow miss those examples on page 98. I think my issue is just as you suggested: it’s not really clicking yet, though I understand the material if I go over it slowly. I may need to review this part a few times.
SeanThanks. I reviewed the video in unit 3, which did help to jog my memory. Now to retain that info!
