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.

Tip

Rebuild the fan when it stops working!


Caframo advertises a feature in this fan which will shut the fan down if it gets too hot, and then start it again when the fan cools down. In fact, this feature is heat sink compound between the two halves of the body (which are each heat sinks) and the power plate between them. That compound breaks down over time and use. If the fan stops working, take it apart and scrape that compound off (it was silver on my fan), and replace the compound with a thin coat of CPU heat sink compound from an electronics store. Put the fan back together and let the compound set up over night before placing the fan back on your stove. Should work like new!

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.

Why does a table fan slow down after some time?


Revolving blades in table fans pushes out air towards the front by creating a vacuum at the back of the induction motor. Other than providing air flow, the gush of air also cools the motor. Over time, esp if used in a polluted surrounding, dust collects inside the motor and causes friction in the shaft. If left for a prolonged period, this friction causes heat eventually drying up the lubrication, causing breakdown in the motor amature windings and also a leaky starting capacitor, thus slowing down rotation and also a complete failure.

2. Fans must be regularly taken apart, cleaned and lubricated. It is fairly easy if you are willing to learn. My India made Usha brand table fan is 48 years old and is still running smooth - just changed the start capacitor last year and my National ceiling fans are more than 35 years old.

3. In fact all moving parts in any equipment must be periodically taken apart, cleaned free of dust and grime and freshly lubricated. It will outrun your lifetime and serve the next few generations.

What is the power system for ecofans - these are the fans / motors which run on electricity generated by temperature differentials in two different and adjacent metals. I would likt to build my own if...


The power source is a thermoelectric module (TEG). Failure of this module is the most frequent cause for fan problems. You can get replacement modules for these fans on eBay.

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!

The most likely problem is either mechanical binding (lack of lubrication) or a bad thermoelectric module. You can get replacement modules for these fans on eBay.

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!
