Reminds me of trying to repair two consumer items recently - one was a Karcher water blaster (pressure washer?) I had to snap off about 10 plastic tabs on the outer case just to get to the pump and motor, only to find it was completely enclosed and could only be accessed by buying a whole set of special tools (you know those weird screws they use to stop you getting in) so I gave up at that point and amazingly I ended up selling it for 10 bucks to some guy for "parts". The other is a coffee maker that had a well documented breakage that caused a leak - the replacement part was available but for a pretty high price, but there was a hack floating around online that if you could succeed at pulling it apart without breaking - again - tabs - you could "fix" it yourself. I of course broke the tabs again, but amazingly I also sold that thing to some guy that needed the power switch assembly off it. Dude - that fridge is massive!
I agree with you on the obvious wastefulness, which is deplorable. If ever we should manage to price all costs correctly into an appliance like this, environmental, recycling, extraction and so on, things may change. Also customers do not care much about longevity.
What I was pointed to in a bunch of reddit comments was that there are actually nice devices on the market, in the commercial/industrial segment. I will for sure look into that when I need to replace an appliance in the future.
you only have almst 1400 subscriber wtf i learnt from you, i guess maybe its having that one video getting shared by a big youtuber or collab or maybe its filming and editing anyway love the vids i like your mindset i come from a country that lives by repair don't replace
Whats the purpose of the freezer-fan? What does it besides circulating air? It has to be a different system for a reason, you can't use every kind of motor at -30 °C so maybe it requires a different kind of technology. It looks like a DC motor and there is a transformator, 94V-0 could mean it's variable for different kinds of setting and functions.
I recently helped a friend to fix kinda newish freezer (5-8year old). The controler board had faulty capacitors so it was rather easy to fix it. Just take the board out, desolder the caps and put new ones. Easy. The price of the board itself is about 30% of the price of the whole fridge. But the surprising part related to your question was the fact that it took about 24h for the fridge to get to the nominal 4C temperature inside the cooler unit. That blowed my mind as I remember old fridges which could get chilly inside in about 20-40 minutes. I think the fan there is because the evaporator is tiny (saved materials) and cant cool down the full volume of the fridge without forced air circulation. So basically they save a bit of copper on evaporator and compensate it with the fan. Thats my theory.
I don't really know what the fan is for either, most freezers that I have seen don't have one. You could be right that they put the bare minimum in for cooling and the fan is there to kind of "help it along". If anybody reads this who designs these things, feel free to enlighten us :D
I've since figured out the little circuit and repaired the fan. I was wrong about 3 things in the video, 1) its not a shaded pole motor, but rather a single phase induction motor and 2) its not a thermal fuse on the pcb, but rather its a 50ohm power resistor and 3) its not actually the resistor that failed but the PCB itself. The motor is interesting in that its a single phase induction motor which is commutated by the little IC (a schmitt trigger) together with a rotor position sensor, which is a bit unconventional. Now I have no idea why they would choose to use this configuration rather than a cheap shaded pole motor, which is a perfect application for fans (low starting torque). Perhaps there are some thermal limitations. Anyways, I have replaced the power resistor and resoldered on the PCB and the circuit runs perfectly fine, fan works. I think the failure mode was ice or water ingress which shorted the leads of the resistor, causing a high current to flow and therefore overloaded the little PCB traces.
These have to have increasing profits every year in a capitalistic society. They have already made everything as efficient as they can. The only thing left is to increase sales by making everything as cheap as possible and not easily fixable, so the consumer buys another one in a year or two.
I slightly disagree with the last argument. The client have no idea if the device is repairable. They cant judge that before they buy the thing. There is no way for the demand to exist at this time. Even you, smart guy who can fiddle with the device had no idea how hard it will be to service the stuff you own. How much each part would cost and how often it would break. After you finish this repair you have no idea if the pipes will stay seal or if anything will crack and let the refrigerant to escape or something become loose and start making noise. Etc, and so on. We can create this knowledge by putting into customer heads the ideas about fixing the devices and how to check if there are independent suppliers of the parts. But thats not easy. Its not easy for anybody let alone the poor clueless customer.
First world problems to the extreme. Your overpriced, luxury fridge craps out after 9 years of service and that's somehow indicative of the evils in the world. Cry me a river. It's also pretty funny how you clearly don't understand what any of the parts of the fridge are supposed to do but you'll still complain that they're either overbuilt or designed to fail.
Dang dude did you just wake up mad and ready to argue lol? He's just expressing his input or opinion on the matter...no need to bash the guy in the video if you don't agree :/. Its a pretty well made video (in my opinion) in which he just goes on about the repairability of the fridge as well as other conjecture that ties in with his base argument. Feel free to make your own opinions/arguments but I generally don't think insulting anyone's genuine input will make a positive impact on the overlying argument. Positive criticism can go a long way.
@@95LUCKgold I don't disagree with what the guy said but you'll have to forgive me when I say that it's old business to complain that many products are no longer designed for repair. Pretty much every take-apart-and-look youtube channel (ie, AvE) mentions everything Ivanov said but also have some knowledge on the appliance to lend to the viewer. This vid just comes across as vague fist-shaking and complaining.
I'm not sure what you wanted to say with this comment, am I wrong for trying to create some discussion/attention about this issue? Its not an engineering breakdown of the fridge, I didn't want the main message to get muddled by going into deep technical discussion which 90% of the people who watch this wont care about. I will likely create a second video about the little fan, which I have since figured out how it worked and fixed and in fact the circuit and function is kind of interesting. If you want more technical stuff wait for that video :)

You are totally right man. I was think about exactly this as I was editing.
