Repairing a Kenmore clothes dryer

I’m posting this as a place to store my notes concerning repairing our dryer. Feel free to ignore.

About a month ago our clothes dryer stopped drying. It would still spin, but it didn’t get hot. Its an older dryer, having come with the house, and it had done this once before. I was all set to call our repair man again, but Teri thought it might be worth while to do the repair ourselves. So after a week of not having a dryer (or possibly two) I finally got tired of it and started searching on the internets.

Searching for “kenmore gas dryer spins but no heat” gave me lots of results. The best was the two videos below. They’re not the same dryer as we have, but all of the parts are pretty much the same. Teri was right. Dryers are dead simple, so working on them in only a matter of looking and testing.

Sears Parts Direct has a full diagram of the dryer, and allows you to purchase many of the parts you need. It was an invaluable source for learning the names of things. That way I didn’t have to show up at our local appliance parts store and ask for a dohickey, or a thingamajig, both of which I was liable to otherwise.

 

 

Opening the dryer

There are two black metal clamps that hold the top of the service panel in place. You can see them in the next two photos. Slide a flat-head screwdriver along the top of the gap between the panel and the dryer door and over the top of a clamp. Push down on the clamp and it should release enough for the panel to move forward. Release the clamp on the other side and the whole panel should pivot towards you. Lift the panel from the bottom pins (see third photo) and set it aside.

The next thing to remove is the air duct which is the olive green part in the middle. Make sure you take the lint trap out of the dryer first before attempting to remove as it rests inside of the duct. Manhandle this part and you’ll break the lint trap.IMG_2661

 

 

The air duct is held on with two screws on the top, and a metal leaf spring on the bottom (see photos). After the screws are removed the leaf-spring can be slid along the white frame to the left to clear the duct, or it can be bent backwards enough to allow the duct to clear.

This is what the dryer looks like with the duct out of the way.

Pull out your ohm meter and set it to 2k ohms. This works pretty much like a continuity checker. Any change in the number below 1 means the part is good. Some parts, like the igniter coil, will have some resistance (the meter will read 0.35 or so), which is fine as long as they still have continuity.

The first thing to check is the radiant sensor (also called a thermal fuse) and the thermostat. They’re found right in about the middle of the dryer, right above the orange sticker on the light green ducting. The radiant sensor is rusty looking part to the left with the black and blue wires, and the thermostat is to the right with 4 wires. Check for continuity across the long ways on the thermostat, and across the two pins of the radiant sensor.  If neither one works, then replace. Otherwise move on to the next step.

Burner assembly

Unlike the second video, there are 4 things to check in the burner assembly, not 3. They are the valve coils (or solenoids, or just coils), the glow bar igniter, the igniter thermal fuse and the thermostat. The valve coils are easiest because they’re the two black parts near the front. (See the second video to learn how to test them.) The glow bar igniter can be seen just to the left of the coils in the first photo. It has its own thermal fuse just to the left of it. The final thermostat can be found on the top of the burner duct (the tube the gas burns into). You can see it near the top of the last photo, the one with red and blue wires going to it.

Two cool things I found

I got a little bit of research time in today, and came across some interesting finds on teh interwebs.

#1 an interactive map of the ocean floor. Think Google Earth, but underwater. Its pretty darn cool to look around at stuff. There are mountain ranges, canyons, etc. all existing underwater. You could float right over them and never know they were there.
Note: If you’re seeing a whole bunch of brightly colored lines you might want to uncheck all the boxes on the left.

 

#2 A completely crazy secret Christian sect in Tsarist Russia. They were called the Skoptsy, and they took the idea of living a pure life to the extreme. Apparently they read Matthew 18:8: If your hand or your foot causes you to stumble, cut it off and throw it away. It is better for you to enter life maimed or crippled than to have two hands or two feet and be thrown into eternal fire, and took it quite literally. So if you found yourself sexually attracted to the wrong person, these guys thought the best solution was to sharpened their knives.

I get spam…

This one was really fascinating to me. It reads almost like poetry. Like its intentional, not someone who isn’t fluid in English ramming random sentences together.

If it doesn’t have an MOE, its not the Truth

We talk about “truth” a lot, especially in politics. And what I’ve noticed is that we seemed to have blurred the lines between the things that are true, and things that are not. That is, there appears to be little separation between the things that can be verified as facts, and the things that are opinion. My secret pet theory about the fruit on the tree of knowledge (you know, the whole Adam and Eve story with the Serpent and the fruit) is that by eating it, it allowed us to mix up fact and opinion.

Skepticism as an Anitivirus

I went to a movie with some friends the other night and afterwards we fell into a discussion on alien life on our planet. One of us brought up that an ex defense minister of Canada believes there are E.T.s living among us. What’s curious is I found myself taking up the position of the skeptic. Apparently something I do. A sort of devil’s advocate to friendly discussions. Perhaps this is because of the way I was raised, at least in part, but I think there more to this going on.

We live in a world of belief. We see things and apply belief to them. If you’ve read Michael Shermer’s rather wonderful The Believing Brain, then you’d know that belief is our default mode to understanding. Rationalization comes later. We literally believe things, and then rationalize them, not the other way around. And this is true for everyone from the most ardent scientist, the the most delusional religious zealot. The only difference between them is not the way they approach what they believe, but how they prove to themselves the things they believe.

Let me unpack this a little bit. Both the scientist and the zealot will disbelieve things that run contrary to their understanding of the world. This is understandable. If I tell you the moon is made of green cheese, you will disbelieve me, because this information is counter to what you already believe. But what if I tell you something that is untrue, but is similar to what you already believe? That’s where we run into trouble. Again, its not just you or me, but all of us. When we get information that is similar to what we already believe to be true, we are far more likely to accept it as true. And, heres the important part, when we get information that proves false something we believe to be true, we ignore it, or we try to tear it apart, usually via a whole host of false arguments. We say the author slept with his cats (which is called an ad hominem), or the author obviously didn’t consider the intergalactic aliens (a red herring) or we claim the author cannot be correct because no “real” scientist would make such a claim (a no true scotsman), or a whole host of other logical fallacies.

My problem isn’t that people believe in things, or that belief is dangerous (belief can be dangerous, but it can also be helpful). Its that we believe too easily the things we like, and believe too dubiously the thing we do not. Belief than becomes a way to keep our ideas consistent, but not necessarily correct. There’s no built in system to determine if what we believe to be true is actually true. From the inside our own heads we cannot tell.

Worse still, when we’re exposed to information that is close to what we belief, then we are prone to spread it around. Think of an idea as a virus, and our brains as their hosts. If you’re brain is infected with the belief that X is true, you will pass on this notion to other brains. But only those brains who believe similar ideas will be susceptible to your virus. So brains that believe X is false will probably not get infected, but brains that think X might be true could get infected. Again, this is not bad in the main, but there is no way to determine if what we’re spearing is true of false.

(as an aside, this is the whole idea behind the concept of memes. The idea was that ideas spread like viruses, passing on their information. Since ideas don’t have genes (that is, they don’t replicate with genetic material) the way to explain them was to develop the ideas of memes. A meme being the genetic material for ideas, sort of like dna.)

So what we have are all these beliefs being passed around, with no way for the those infected with these beliefs to tell if their beliefs are true or false (or in-between. Assuming everything has to be true or false is yet another logical fallacy called a false dilemma).

What’s interesting to me is what doesn’t get passed around as easily: Anti-belief. By this I mean the entire logical structure needed to eradicate a belief. For instance, If I say Global Warming is a hoax, I’m not passing around the proof that climate change is not real, rather I’m passing around my belief that it isn’t. In other words, I’m nearly passing on my belief. Anti-belief does not come in an easy to digest packet that is readily consumable. Moreover anti-belief is highly specific to the individual. The information that may cause me to no longer believe that X is true will more than likely be different for you.

So what does one do when presented with belief? Especially when we are constantly bombarded with belief, and have to work hard to find anti-belief. The only solution I can think of that we can do as individuals is to attempt to disbelieve every belief we encounter. That is, to be skeptical. Mind you, this is much easier to do when we’re exposed to things we don’t believe already, and much harder when exposed to things we’re more susceptible to. But still the only way to stop being infected with some beliefs is to attempt to not be receptive to any belief.

Does this work? What do you believe?

A culture of consumerism, or how we saved ourselves with advertising

A good friend of mine posted a great article on the effects of consumerism on our culture. I found it on FB, but thought it might be better brought over to my blog. You might read the post for yourself before digging into my response below.

I think this is a wonderful article, although I had a few quibbles. The author has the history a bit mixed up, but the end result is the same.

Consumer spending as a force in our economy (over 70% of the GDP, last time I looked) was not designed as much as it was an accident. Call it a feature instead of a bug, if you will. Like many things in our semi-capitalistic economy, it came about both by consumer forces, and a need to see a greater return on investment. Its the superhero of this story that is surprising.

Today the concept of advertising is deeply rooted in our culture, but it wasn’t always so. If you look at media (like newspapers or magazines) prior to WWII and indeed prior to WWI, you see very little of what we call advertising. Oh there are ads back then, but they are amazingly transparent to our modern eyes, and they are not nearly as frequent. Its also important to note that during the war years consumer spending was deeply curtailed. Many of the basic needs were rationed, like petrol and food stuffs.

The big shift came as  a result of the post WWII depression. We had all these factories used to making all this stuff, only it wasn’t being consumed by the war department any more (war being the best consumer ever made). If you were invested in lots of factories (which a large percentage of the wealthy had done back then, after all it was patriotic and profit making) what were you to do? You wanted to get a good return on your investment, but how was that going to happen?

At the same time you had many people who had worked hard and saved during the war (or had worked hard in the war), and were looking for a way to reward themselves for their efforts.

Enter the savior to our economy. Of all things it ended up being Madison Ave. in NY, and by extension all of its ad men. Advertising became the hook to pull consumers into the market. First by radio, and then by glorious TV, we extend the idea of buying our way into a better economy one ad at a time. And as advertising became increasingly profitable more investment was put into the process of designing and creating ads. It was this investment, it was this interest in spurring our economy, that allowed advertising to finally grow, and become more sophisticated. Trying new tricks, new techniques, new mediums (like TV), and new relationships (like advertising and sports), averting grew until it started to become one of the most dominate cultural forces in our country.

As advertising grew in influence it also became more sophisticated.  Ads used to be garish, and overly broad, using pitifully simple themes to get us to buy. But now ads have evolved to become more and more sophisticated as we’ve learned to tune out the simple ones. Today ads on the internet are often deeply targeted. If last week you did a search for a new rototiller, don’t be surprised if this week your favorite blog features ads for new rototillers. Advertisers have mixed the power of search engine queries with the power of flexible web-pages, a process that is intrinsically complex.

But here’s the tricky part. Just like you don’t have to buy anything sold in an ad, you don’t have to buy our ever present advertising culture either (or any other culture for that matter). Alas, the price for this is not fitting in, which is a difficult feeling to overcome. We’re wired to go along with the herd (which is one of the ways advertising works), so standing out goes against our biology. And don’t try pretending that advertising doesn’t work on you. Studies show that the people most likely to be effected by advertising are the ones who claim they are the lest likely.

If you’re looking for ways to shed the effect of adverting culture from your life, I’d recommend you look to the people who have been shunning popular culture for millennia: Artists. Check out your local painters, song-writers, poets, authors, actors, etc. All of these creative types have been thumbing their noses at the world for years. Practicing their own versions of anti-culture. Check them out. Get involved. Create. And learn to ditch the cultural norms which are holding you back.

The kind of notes I send to myself…

Cool idea 11/24/2013

A heads-up display on a motorcycle shows the driver a image of a motorcycle in front of him that he should follow. The image turns color to represent speed (more green for faster and more red for slower) flashes yellow if the driver needs to really pay attention or if they need to brake or accelerate hard. A radar plots a path through traffic so all the driver has to do is follow the image and they can drive much faster than normal.

Also a motorcycle is made of a very strong but very heavy material. Something much stronger than steel. The motorcycle weighs 8-10 tones. If a car pulls in front of it the motorcycle just pushes it aside.
