    My dryer is a Hotpoint and after just one load done the dryer just wont start up again. A friend said it was the thermal fuse and he replaced it but i didnt get to watch him. So now i was assuming i need too purchase another thermal fuse and try to put it in. While looking up where the best place Is to purchase one i ran across this video so im definitely going to take dryer apart and clean it but my son got back there while i was gone and i guess he had trouble getting the fuse out because he has broke it. Im hoping that he hasnt left part of it in the dryer. Is that the part where the thermal fuse goes back into( the part that im supposed to whack lol ) ? If so do I purchase a new fuse since mine keeps blowing then attempt this and then put the thermal fuse back in or are yall not putting a fuse back in😮 my last dryer electrocuted me and threw me through the kitchen ( i wasnt aware that the last person to hook up previous dryer left wires exposed) so im really gunshy but i have to get something done i cannot stand going to the laundry mat. Thank you for all of your help how long is my vent tube that runs from the back of dryer supposed to be because i got some new and i don't think they trimmed it

    That radio is absolutely beautiful! Did you do the whole restoration on it already? Or did you receive it in that condition? Any way, can I ask where you got the schematic for it, and how I could find one? Like I’ve said the Midwest I have is a JC 916 model, so a little different, but similar, mine has a lot more rust and disgust, but did fully work. No bezel on the model I have, just the brass two tone lines and with have a few rust spots, I’ll have to go back and use the 5 gallon bucket with copper pipe trick I saw you use in a previous video.

      Many a successful radio repairmen started with only a crappy 1Kohm/V VOM and tackled many repairs. The test equipment its an aid to your brain, not the opposite. If you know your fundamentals, you can work with very little. Test equipment is nice, but most radios can be repaired with very little stuff, IMO. Vern is showing this beautifully in the video, as it can be seen.

    • @theradiomechanic9625
      @theradiomechanic9625 Před 12 dny

      Tons of ideas, but not enough information to go on. What test gear do you have? Is there any sound from the speaker? Touching the center of the volume control should produce a hum in the speaker. Use another AM radio to see if the local oscillator is running (watch my latest videos on the Stromburg Carlson). I assume you have a schematic? It should show voltage references. Check all the voltages.

    • @lucasgibbons2841
      @lucasgibbons2841 Před 12 dny

      Thanks for the reply! I do have the schematic, I've went through the voltages, most are reading a touch high but they seem to all be there. I only have a DMM. I get a very low hum from the speaker, that intensifies with tone adjustment. I also get a noticeable pop noise when changing from normal to brilliant sound.

      @@lucasgibbons2841 Ok, so it sounds like there is some life. Again, try touching the center of the volume pot. This should produce a very healthy Hum. If yes, then the amplifier stages are working. If not, then something is faulty in the amp chain. Do you have any sort of signal source like an audio generator. Inject signal into the grids of the 7C5 tubes. If these work keep moving towards the 1st Audio 7A4. etc. No signal generator? use a long piece of wire as a noise source. 10 feet or so will pick up all kinds of noise and can be used for this test. (no need to connect the far end.) Review my video on the Stromberg Carlson and see how I check for local oscillator functionality. (With AM selected). Find someone with a tube tester. Check the tubes.

    Hi Vern! First of all I love this type of videos where you actually reason on camera, showing the thought process and the steps needed to fix such a tough receiver! The trick to check the local oscillator was very interesting! I have a question about your bench, specifically the layout. I notice how most of your instruments are either eye-level or bench level, so that most of the time a set on the bench covers them partially. This feels important especially for such a tool like the VTVM, but it seems that for your works just fine. What's the most useful bench layout in your opinion, regarding test equipment, parts etc especially for someone whose lab is in a cramped basement? Do you have a method in arranging your bench? Also, please tell us some stories about your repairmen past, it would be really interesting I think!

    • @theradiomechanic9625
      @theradiomechanic9625 Před 16 dny

      Hi Will, Your question on the bench layout brought a smile to my face. I have been at this since the 70's and have never found the perfect layout, or enough bench space. (Is there such a thing?) If you look at the layout of the 10 Buck Test bench the VTVM is actually hanging from the bottom of the shelf. While on my other bench the VTVM which has a huge meter face is sitting on the bench. I usually have at least one scope sitting on the bench, while spectrum analyzers are on the shelf. Signal generators, frequency counters etc usually are on the shelf. Usually. Had a bench years ago that was over 5 feet deep. Lots of room for test equipment and room to work. However, I had to keep standing up to reach the test gear. One shop I worked in had benches 16 feet long, the issue here was I always needed the meter that was on the far end. Just can't win. My Ham radio layout has the Radios on the bench, accessories are mounted below the shelf above the radios, and Linear Amps and tuners are on top of the shelf. My suggestion is build the biggest bench you can, add a shelf over it, then work with it for a while. It all comes down to a matter of personal likes. Thanks for watching and for the insightful question. I'll see about telling some tales. Should be safe after all these years.

  • @ericrawson2909
    @ericrawson2909 Před 18 dny

    Your metal bench makes me nervous. The likelihood is you are in contact with it when working so your body is earthed if the bench is earthed, so if you touch B+ the current will flow through you. With my wooden bench and floor in a dry environment, I could touch B+ and the bench and not get a shock. I need to touch two different voltage parts to get a shock, not just one. The other possibility is that your bench isn't earthed, so it takes on a voltage from anything that touches it, like a live chassis.

    • @theradiomechanic9625
      @theradiomechanic9625 Před 18 dny

      Every set on the bench is connected to an isolation transformer. It is as safe or dangerous as any radio when you touch the B+. Having a wooden bench and touching the B+ isn't any safer if you come in contact with the chassis. Always work with an isolation transformer is the advice I give in many videos. Even when working on sets with transformers as the AC is always present. Thanks for your concern, but I have over 60 years experience doing this. Every shock I have ever received was when working on a wooden bench. Isolation transformers can be had for as little as $50 brand new, and much cheaper second hand. Cheap insurance.

      Thank you sir, you should visit their website. They have over 100 of these units running 24/7 producing parts for machines they sell as well as other High Dollar units making parts also. They only use injection molding on legacy parts. Amazing factory.

    You don't have to get rid of your current camera to add another one to your setup. You can use one for one and the other for the other.

    This was a great educational video with lots of troubleshooting of weird issues Vern.

    The 474 should have been 473, (if wanting to use a 0.047uF). Makes you wonder who these people are! They obviously DON'T understand electronics!!

    This one was a stubborn one, but worth the struggle. I enjoyed the video, thank you! Also, you don't "talk too much". Nonsense - it's interesting to follow your train of thought and fault finding.

    I wouldn't doubt it's measuring flow. their pitcher style water purifiers used to have an interesting mechanical thing inside that measures how much water has flowed through it to determine when it's time to change it. there could be a second hall effect sensor soldered to the pcb on the back side to pick up the turbine pulses. they also could be doing some timing as well, so that once a new filter is installed it will start a timer and "expire" it after 6 months or whatever in addition to measuring flow. it probably sleeps and only wakes up once a second or so to test the hall sensors to save power and will power up fully when it sees a change in the sensors.

      The unit comes on when the flow starts, but goes to sleep after 6 blinks no matter how long the water is on. I just change them every 4 months.

    A long video but I didn't notice. Quite a can of worms there Vern, well done sorting it all out. It's interesting to watch the radio operation come together a small step at a time. Every small repair resulted in getting closer to a functioning radio. Good watch, thanks Vern 👍🙂
