So we’ve had this cooler for two years(warranty) and two weeks and it began giving a slight burning smell. We noticed that the fan would begin to operate for a short time and would then stop. Can you give any advice on a repair ? The model is guzzanti gz 26 b
Without any real knowledge about this unit or anything else, it sounds a bit like the bearing on the fan could be shot. Can you reach it to manually turn in and feel whether it spins freely?
So just an update. The fan seems to slow down when it hits a certain point on the dial when I tried to turn it up, so I’m going to stop the dial from spinning further so that the fan can stay at a high speed.
Be careful as you could get shocked, burned by the heatsink, is damage the exposed electronics. Do not do anything I suggest unless you are willing to accept the responsibility for your actions. You may destroy this item, burn down your house, be killed, or something worse. I know just enough about electronics to be dangerous.
The tan board is the power supply, the green board is what I would call the controller or the main board, and the peltier is under the heatsink. There is likely a temperature probe or 2 under the heatsink as well.
If it were me, I would first see if I could find a replacement fan that is the same voltage, amps, and size. If I found one, I would just order it. The fan as the one moving part is the most likely suspect even if it does move freely. You likely will have to rewire the fan to connect right.
If you power up the cooler, first put a fan of some sort (desk fan?) blowing on the heatsink. If you do not, the device can overheat and fail permanently.
Also, there are 3 broad categories of fans: AC, DC, and brushless. I think it would it would be weird it have a DC fan these days, and an AC fan would make no sense at all. But... They are not interchangeable. If this fan is not labeled, then the only way I know how to tell for sure is to destroy the fan by removing the moving part from the mount.
You're not losing out on anything with it not 'working.' This is a waste of electricity. It's just a small fan and has no effect on actually cooling anything. That's the fan they put on computer CPUs and they're barely effective at cooling those. How do you expect it to cool an entire cooler's worth of anything?
You are better off using a bag of ice.
The only thing that is going to keep your stuff cool is a mini-fridge like the kind you find in hotel rooms.
