- This unit had a power supply issue which looked to be a common failure via complaints on reviews via Amazon. Searching on the internet all I found was board swapping and no real repair to the original power supply. A lot of bad info too from people that don’t seem to understand how power supplies work. Component level repairs seem to be a lost art these days so I thought I’d show how to fix this simple issue and hopefully others could benefit from this info to practice component repairs themselves.
Caps I installed were high temp / high frequency to assure long life:
(1) 10uf @ 50v
(1) 100uf @ 250v
(2) 1000uf @ 50v
Fixing the original components yourself makes the drinks in the unit taste so much better! ;)
Here are some parts links. Took awhile to get them as they were coming straight from China but they showed up within a couple weeks:

At the link above I ordered the 50v @ 10uf and the 5v @ 1000uf in their options menu.

I ordered the 250v @ 100uf from their options menu.
Make sure you have a power supply issue before ordering. If the power supply seems weak then it’s definitely caps. Nothing else really goes wrong with the power supply other than that. Solder joints are usually not great and could use a reflow in some spots.
Easy way to verify if it’s power supply is to detach the output 12v wires from the power supply and then attach the 12v car adapter and see if it works. If it does then the power supply needs attention. If it still doesn’t work then something else is a problem.
The switches on the back can be finicky and cause intermittent power issues too.
Good luck!
Hi, I confirm that the 10MicroF/50Volts capacitor was the culprit. I got the AstroAI LY1906 Model, with the same problem of the flickering light in the front. Just change the capacitor and way to go. If you can acquire the rest of the capacitors, like the video says, change all... but in my case, just with changing the 10Micro/50 Volts Capacitor do the work. For the tech you out there, i test the bad capacitor and mark 9.75 microF, so i change it. Thanks Jack for the video advice.
You have successfully repaired probably the least efficient system designed to cool stuff. Congratulations.
Your the one who clicked the video smartass
I have a similar model and a coke edition, both probably have the same problem, thanks for the video!
Likely is the same issue. I purchased a couple of Budweiser units to use the parts to make cold cup holders for my truck. One of them had the issue, brand new, straight out of the box, lol! Seems very common.
Hi, thank you for posting this! I have this same mini and it doesn't get cold at all. Instead it was hot. Bought it on fb market the other day plugged it in and put cold setting on. Green light on back works and three mode lighting on front mirror works... Just wondering what would you recommend to solve this issue? Any advice or suggestions are appreciated. Thank you!
My daughter's just stopped working all together no light no power no nothing
Thank you for the great video. I have a HomeCraft mini fridge that looks very similar, but won’t heat or cook and the fan doesn’t run at all. Would those same components work in mine ?
Can please help me sir where can I go to fixed it my light is not working
My led light turns on when I plug it in but when I turn on the cold setting it turns on completely and the green light on the back flickers once
Thanks for the video. By any chance you still have caps you use to make it work left. I would like purchase your left overs.
By chance, do you still have the links? I'm going to attempt to fix my lady's makeup fridge, and I want to make sure I get the right parts.....great video BTW

Hey Mr. Jack.. This isn't fridge related, but hoping I post this on a newer video, and you get the change to answer. Can you talk about transmission failures. I understand the 2009 failures, but for other failures, do you attribute them to poor maintenance (i.e differntial/transmission fluids not being changed often enough), mileage, too much horsepower and torque, or abusing the car (i.e, constantly using launch control). I'm wondering because i'm the owner of a stock 2012 GT-R with over 120K miles.. and never had any transmission issues. I'm "finally" considering modding (fairly conservative), just maybe a mid-pipe, airbox, and perhaps a new fuel pump and injectors, but don't want to grenade the transmission. Also.. are there many changes in the transmission hardware between years of the GT-R? Thanks so much. If I ever have an issue with my transmission, i'll definitely be calling you guys.. or driving up if I can still drive. Or.. as a precaution for mods.
Hey sorry I don't really check messages here. Email me directly at shop@jackstransmissions.com and I can help there as it would be more consistent as I check my email every day.
What video camera were you using?
Any idea how I can get the light from turning on, on it’s own and flashing?
Thanks so much.
The switch with the LED lights burned out in my unit. Do you know where I could buy a new circuit board with the switch and the lights?
Mine's doing that. Imma fix it.
So i have a mini fridge the doesn't cooling or heating so i thought to replace the power supply with 65w laptop charger does it work?
Without diagnosing the issue properly, replacing the power supply is just guessing. There is nothing wrong with the original other than the caps. It would be cheaper and easier to just fix the original power supply.
If you must do it the hard way then your power supply will work it's 12v and has a wattage rating higher than the label on the back of the fridge.
I moved from Ohio to Florida and seems my mini fridge broke along the trip and now has this surging issue with the light. The fan spins fine. I’m compfortable trying to solder (even thought I’ve never done it before) but is it worth money wise to buy a soldering kit for this or is it cheaper to get a new fridge
Might be more expensive to buy a soldering kit and you might not even fix the problem. But you learn a new skill along the way which money can’t buy
Mine blinks once and than does nothing, what does that mean.
Hi, I have a mini fridge I’ll like to fix also but it’s very complicated for me since I don’t have money or the supplies it seems the power for turning it burned down so could I ask if you could check it out if I send it to you through mail and you could fix it for me?
How do you take the caps out and replace? I don’t want to do any additional damage?
I have been soldering since I was 8 years old so it's easy for me. What I do is melt the solder on 1 side and tilt the cap UP on that side. I then do the same on the other and repeat until it's off. This way you are going quickly to keep the heat out of the board and not trying to suck the solder up which can also overheat the board. Install is the same. Melt one side and run the cap through and then use fresh solder when done to make it nice and clean. Note- caps have a mark on them and on the board for polarity. If you put it on backwards it will likely explode.
I don't see the 5v @ 1000 on the ebay link is it 50?
Yes 50
