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

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!!!

My Ecofan slowed down and finally stopped working after using for 2 years. i bought this as a replacement for the TEC and it has worked now for about two months. If you replace your TEC, use thermal grease sparingly on both sides and more important, hand-tighten the screws down as evenly as possible. Make sure that the hot and cold surfaces are parallel, then torque another half turn or so. Better to be too loose than too tight. Good luck!

Just as advertised and perfect for my application

I used this to repair a stove fan. It works perfectly.

as described

Used this to replace the cooler module out of my table top cola cooler. Installed it no problem and it is working great.

Installed it the same way the original was installed yet had reverse effects on my mini fridge, it got hot, burned out since the cooling fan was on the wrong side. My mistake but still no instructions as to which is the hot side and the cold side. If I decide to buy again I’ll test it first with low voltage.

Worked for 30 seconds and consumed 2.25A @ 12VDC. After that, it was open circuit when connected but came on after gently tapping it once or twice. Then, nothing. All this happened while the unit was sandwiched between a tall CPU cooling heatsink and a custom made copper block. Finally, I tried to squeeze harder and broke it. It is hard to return something that is in million pieces, I'll try anyway.
