Mcredy Karcy TES1-12704 12V 4A 36W 30x30mm Heatsink Thermoelectric Cooler Module High Power TEC Generator Cooling Peltier

We had an eco fan that accidentally got knocked over and ruined the original power cell. After we’d replaced I found this power cell and decided to give it a shot. After wiring it up the old fan started working again and it even seems to work better than the newer fan

I’ve been using this thermoelectric module for over a year now, and it’s still performing flawlessly. It was a direct replacement for a failed module in a small thermoelectric cooling device, and it brought it back to full working order. Installation was straightforward if you're comfortable with basic soldering. Just make sure to apply fresh thermal paste—reusing the old paste isn’t recommended and can reduce cooling performance. A clean surface and proper paste application make a big difference in efficiency. This unit has held up well under regular use, and the cooling performance has remained consistent. For the price, it’s a solid and reliable option. Pros: Long-term reliability—still working after a year Easy installation for anyone with soldering experience Good performance in small thermoelectric cooling applications Affordable and effective replacement part Tips: Use new thermal paste for best cooling results Double-check polarity before soldering to avoid damage Cons: Not beginner-friendly unless you’ve soldered components before If you’re repairing a small thermoelectric cooling unit, this is a dependable replacement that delivers great value and performance.

My favorite mini-fridge broke down on me. It would no longer stay cool. It was just room temperature inside. The problem was that the peltier device (the white square device pictured) no longer functioned. These are inexpensive devices, but they only last around 5 years. As you can see from the date stamp that is what happened to my mini-fridge. Fortunately, I was able to remove the back of the mini-fridge and replace the the peltier device with this device I am writing the review on and it worked perfectly. It's pretty simple to replace and does require some wire splicing. As a test you can replace the device and then turn the unit on for 3 seconds and make sure the sides are set down correctly (there is a hot side and a cool side). The cool side is placed toward the fridge and hot side is the one that goes against the heat sink. Don't forget the thermal paste when replacing this component. All in all it was a 30 minute fix and my mini-fridge is back in working order. Thanks Amazon!!!

Tried to repair a micro fridge with this. The first didn’t work, the replacement arrived two days later and was perfect: too hot to handle on one side, too cold to hold on the other. Unsuccessful repair, but not because of the Peltier module!

Product was as stated, works great
