Not sure if you can help me with this. I’m going on my first “call” tomorrow, a freebie dryer problem for a friend. I downloaded the manual from appliantology, but when I open it up, it doesn’t allow me to click on the pages to make them full-screen. Any thoughts on this?
March 20, 2019 at 8:45 pm #15593Nevermind, I figured it out!
March 24, 2019 at 12:10 pm #15597Well, 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.March 24, 2019 at 1:27 pm #15598Hi Sean, some of the schematics on Samsung fast tracks are badly pixelated. I’ve complained to them about this and they say they are going through and updating them.
Post the link to the fast track at Appliantology so I can download it and take a look.
March 24, 2019 at 1:40 pm #15599Oh 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.
March 24, 2019 at 5:50 pm #15601Oh man, at the risk of sounding really stupid, I don’t know what you mean or how to do it.
This is actually a great answer! Part of your fundamental skill set as a competent, professional tech is effectively using information tools to get the job done. Your comment let me know to give you some good tips for using Appliantology as the powerful appliance repair information tool that it is.
Watch this super short video on how to search for files at Appliantology:

Then use your new-found File Finding Fu to find the download page for the fast track at Appliantology. Copy the address of that page in the address bar of your browser. For example, click here to see how I get the address to this page that we’re both conversing on. Past the link here in this topic so I can download the exact manual you have.
Another great thing to do is take the free Appliantology 101 course which you’ll see on your “My Courses” page, upper RH corner of your screen, click here to see a screenshot.

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).
March 25, 2019 at 11:22 am #15603I’m having trouble reading the schematic by myself.
Not to worry, this is normal. You’re learning the fundamental principles in the course and you will master them as you apply them to solving problems.
Now that I know what document you’re working with, I see that you’re using the training manual. This is okay to get familiar with then machine but for troubleshooting, you’ll usually want the Fast Track. I’e uploaded it to Appliantology for you:
https://appliantology.org/files/file/5749-samsung-dv42h-dryer-fast-track/
The schematics in both documents are good quality and not pixelated, which is what I thought you meant at first about “hard to read.” But it sounds like you mean that you’re having a hard time understanding how to use the schematic. Is that right?
I put the machine into self-diagnosis and it showed a code for the door switch.
If you’re getting a door switch error code, then your first move is to verify that the door switch is operating in spec.
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.
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.
Referring to the Ten Step Tango, the first step in troubleshooting is to have a clearly and succinctly stated problem description. This is also the step that most techs fail to do. Just read the topics in the tech forum at Appliantology– most of those guys utterly fail to give a succinct, clear and specific problem statement. Solving problems requires clear thinking. If a tech can’t clearly define the problem he needs to solve, how will he ever solve it?
Your problem statement answers these questions: What is the appliance doing that is SHOULD NOT be doing? What is the appliance NOT doing that it SHOULD be doing?
Post that and we’ll go from there.
March 25, 2019 at 12:17 pm #15605Thank you, I think I need to go back and review this part of the course.

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.

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.March 25, 2019 at 4:59 pm #15606Sean, this is a great question and would be a good topic for a webinar where I could go walk everyone through the circuit. Let me know if you’d be interested in that. In the meantime, or maybe in lieu of a webinar, I have a video where I break down the circuit in these Samsung dryers and discuss troubleshooting strategies. Watch this video and let me know if you have any questions:
March 25, 2019 at 8:23 pm #15612Ok, 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.
March 25, 2019 at 8:35 pm #15613Keep at it, it will click for you at some point.
Do you think watching me show this in a live webinar would help? I’m planning a webinar for this Friday afternoon and could include this as one of the topics.
March 25, 2019 at 8:42 pm #15614One more thought… you mentioned you were overwhelmed with the information at the end of the Samsung Dryer webinar. You can and should rewatch the sections that are difficult for you. It’s normal and expected that you re-watch some or all of the more technical videos in the course.
I remember in Navy A School, Basic Electricity, when I was complaining about how difficult it was to understand circuits, my beloved instructor, Petty Officer Second Class Crowe, told me in his distinctive Alabama drawl, “Brown, learnin ain’t for pussies.” I went back to work.
March 26, 2019 at 8:40 am #15616I 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.March 26, 2019 at 9:23 am #15617What you’re feeling is completely normal and will pass. Just hang on, keep studying and trust that it will click at some point.
Just a side note— I didn’t mean to imply that you were complaining. I was just relating a humorous story of my own struggles with learning this stuff to help you see that even I struggled with the basics. Everyone does. Anything worth learning requires real effort. But most people are lazy— sounds harsh but it’s true. (again, not referring to you at all— after all, you’re here making the effort to learn!) That’s why most appliance techs today do not understand basic electricity and circuits— takes too much effort. They’d rather just know “the answer” — which part to replace— and then move on to the next job.
Keep at it, keep studying and asking questions and you WILL get it!
