Ecofan not working


The problem is most likely a bad TEG module or possibly a bad fan motor. The most common problem is a failed TEG module. Caframo will not sell replacement TEG modules as they require you to return the fan to them for rebuild but the repair is quite easy. You can find the exact replacement on eBay or directly through Thermal Enterprises. They even have a troubleshooting and repair guide for the fan.

How do i fix my Ecofan ?


Does the motor have bearings or bushings? If bearings, they likely need replaced. If bushings, clean with alcohol then lubricate with 3-in-1 oil.

Our Eco fan does not turn. It fell on the wood stove once and bent the fram a bit , then it started working, now it doesn't at all. What is up?


It sounds like something is binding on it. Anything of this type (referred to as a heat engine or external combustion engine) need very low resistance. There may be a bent shaft or a small ding that is rubbing on one of the rotating parts. Good luck.

The metal strip on the bottom, can it be replaced?


There are no replacement parts for this fan available, however I managed to get mine spinning like new after it had died. I took the two halves of the fan body apart, and scraped the heat sink compound off either side of the power plate. I then applied CPU heat sink compound that can be found at any computer or electronics store liberally to either side, and put it back together. The fan spins like new, spread the word!

My ecofan quit working. Blades rotate rough


Sounds like a bad thermoelectric module. This module is what generates the power to run the fan. You can get replacement modules for these fans on eBay.

Ecofan only turns slowly


These fans can be rebuilt! Like many others, our fan died after being placed in the center of the stove top. I took the two halves of the fan body apart, and scraped the heat sink compound off either side of the power plate. I then applied CPU heat sink compound that can be found at any computer or electronics store liberally to either side, and put it back together. The fan spins like new, spread the word!
