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.

Ecofan troubleshooting


Given the age of the unit and the job that it does, it may need to be overhauled and lubricated. This would include removal, cleaning, inspection and replacement of any parts that are worn, lubrication and reinstallation.

I have a Toshiba laptop with a Windows 7 operating system, a few years old. It recently started randomly shutting down - after 10 minutes or so of use, it would just go dead. It's also extremely slow,...


Hi.
the first thing i would check is to make sure there is no dirt or dust stopping the fan from running because if the fan is not running it will heat up and shut down or if the fan is running slow it will shut down.
and for running slow i would do a good clean up get rid off stuff thats not needed anymore.like music,pictures,the more your harddrive has on it the longer it will take to load and run.

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.

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!
