Nice Video and good to see it rescued. H30SR5 is the device marking for the IWH30N160R5. One other thing you shouldn't really use glass fuses for mains protection, you should use ceramic HRC type. The reason is that because the mains is low impedance when the fuse blows violently the metal vaporises and then forms a thin layer on the inside of the glass remaking the fuse but now it can't heat up as quickly so it then very often shatters the fuse completely so you end up with just the end caps left, very often it O/C tracks on the PCB instead of blowing the fuse a 2nd time. You do have the HRC fuse in the mains plug as a backup though. The Chinese are very bad at using glass fuses in mains circuits.

Thanks for that Richard. I've often seen the ceramic fuses in mains devices, but I've also seen glass ones too. I've taken note of what you said so I'll see if I've got any ceramic fuses for the future. Someone suggested a fuse socket, I've actually got some PCB mount ones but totally forgot about them 👍

I really enjoy your videos. You do troubleshooting pretty much the same way that I have done it for many, many years! I think it is terrible that so many people just throw things out and buy a new one. It is such a waste! I have found that most of the repairs that i have done were just a case of bad solder joints! And other repairs were just a matter of finding the failed component and replacing it for a small fraction of what a new unit would cost! It's nice to see that you have the patience to go through the troubleshooting process. Thank you for sharing what you do!

My best guess is someone hit the button without a coil attached. Zvs drivers don't survive being unloaded because they wont resonate and it will just keep the mosfets on and burn them up instantly. Thats an interesting design since most zvs drivers are made to work at 12-48 volts but this one runs on rectified mains and uses a step down transformer on the output. I may have to try making a zvs inspired by that one since it looks like they used a common tv flyback core which i got a few of.

I think what kills these things is people pressing the button without being on metal. If there is no metal in the coil, the Q of the tank circuit is much higher (along with the voltage on the components). The ratings on the devices used to build them are chosen with the assumption that the tank circuit is reasonably loaded. They would not overrate the parts $$$$ just to ensure people can use it as a flashlight.

I think you're only allowed to switch it off via the switch, after which the fan keeps on running until the temperature is low enough. That is what the thermostat might be for. The fan keeps on running until the temperature drops below 75 degrees. You are only allowed to unplug the device after the fan stops running. Welders also work like this. If you just unplug the power cord,the MOSFETs might burn, because the fan can not remove the residual heat. I am just guessing this works like a small welder.

In a welder the MOSFETs are more hot than the heatsink during normal operation. If you unplug the power cord suddenly the temperature of the heatsink will go up, because there is no airflow in the device, This makes the MOSFETs overheat as they can no longer release their heat. Ceramic infrared electric cookers with built in fan have the same problem, their thermal fuse will blow when you suddenly unplug them via the power cord.

Mike knows his stuff that's for sure. But also, he knows that you don't solder a good fuse over the top of a blown one. Same as you don't solder a good capacitor over one that's failed.

These have many uses including heating a carbon crucible full of precious metal.

Personally I don't like these glass fuses on a mains equipment. The breaking capacity of these is barely 20A at the 240VAC, way bellow the short circuit fault current. That means those are not rated to break the current safely at all, the arc just makes them explode and jump onto something else. Better use the ceramic ones, the breaking capacity of those is 1500A, the cord resistance and mains impedance usually keeps the current within that limit.

My son who is skilled in soldering wondered if there was anyone who had never soldered before as it was very amateurishly done a lot of cold soldering. Complained and got a new one under warranty. Worked for an hour or so and appeared to be the "same" person who made this. The fuse that was soldered on had tripped removed it and soldered on the brackets to be able to change the fuse easily. But it doesn't work and my knowledge of troubleshooting components "ended" when I replaced the fuse holder. Tried to talk my son into troubleshooting. But the answer was don't even want to see the "shit" again.🤭 The tool itself is and the principle of how it works is absolutely superb, can be accessed in tight places as there are different variants of the "spirals" and can be bent into shape. AND you only heat that part "the bolt" and since it is fast, the heat does not spread to, for example, rubber bushings.

@@BuyitFixit Thanks❗ Yes I will absolutely use your troubleshooting on my devices. Can guarantee that the son will look like this😲🤥. If I find similar faults and ask him to help me replace them, there is a large company Elfa in Sweden that has components. I can handle a multimeter pretty well. Has a short past as a car mechanic on new cars in the mid 70s (Sweden) General agent for Mercedes but also Audi and Simca😬 On a brand new Simca 1100 (similar to a wv Golf) the high beam switch did not work. I debugged with a "test lamp" From the switch on the steering column to the lamp, the cable changed color 4 TIMES and in one of the "joints" the cables did not fit together. That's when my preconceived notions about French car manufacturers turned out to be correct, at least in the 70s. I will get back with the results. And above all you have a new subscriber just the right kind of topic that interests me.

Nice fix! Did you burn your phone at the end??

@@BuyitFixit probably because it's using a "cheap" version of an inductive heater driver, like ZVS'es - they fail when you "turn them on incorrectly". The components you replaced are the common culprits... The H-Bridge "stalls" and shorts everything.

@@ianhelsbyservices Sadly, no. I cannot suggest a quality inductor driver - those are what usually makes or breaks the retail available "premium" induction heaters. The only "swappable" component is the coil and capacitors. The issue is that quality inductor drivers are usually expensive due to the nature of their requirements. They have 1. sensitive chips to detect the "frequency response" of the coil for auto-tuning, 2. filters to save it from self-destructing, 3. high-amperage, high-speed-switching mosfets - which themselves are already expensive, 4. Bootstrap circuitry - and all of that works mostly specific to the design of the coil (diameter/inductance/thickness/impedance). This is why most people use ZVS drivers as they're "cheaper" than the alternative and require essentially no tuning. But any issues with the power supply or the coil will instantly destroy everything due to transistor failure - the H bridge becomes a full short. Bye bye traces, bye bye transistors, and bye bye power supply sometimes. Most hobbyists use screw terminals for the transistors for quick swapping :')

Don't you love when semiconductors morph into solder bridges?

@@BuyitFixit True. RF bipolar transistors, the high current flange mount ceramic pill kind, almost always fail open ironically

The fact that they solder tinned the high current output wires that are secured by screws indicates some dubious design. NEVER solder tin wires that will be secured by screw/clamp connections. TBH I'd replace as much as possible on something like this even if it measures OK it could have been badly stressed and fail not long after the repair and most of those components are cheap.

@@BuyitFixit Induction heaters are actually quite hard to design in a way that they don't self destruct, a common issue is them not starting up properly and latching on, the Cheap Chinese ones that work of a DC supply must have a decent high current supply, a sluggish supply often leads to latchup and burn out, also as others have said unplugging them without giving them sufficient time to cool might be an issue.

Not at the time, but the coil is insulated and cools down quickly. Even if not, it was only heated to 100c and they use more that that to remove and replace the glass (no screen protector fitted btw).
