    My fan used to turn barely moves with a hot fire in the stove.

    It could be dust/dirt accumulation, but the fan blades move easily when pushed.

    Note that this fan is external power

    I now have two ecofans 802 that are less than a year old. One was sent back to the manufacturer because it slowed down after a few months. They sent me back a "remanufactured" replacement. It also slowed down after a short period and the other fan is also slowing down, I have to give them both a "tap" to get them started but even then they turn slow. Not sure if it's a poor quality product but would sure like to have solution to the problem. I don't see keep sending them back to the manufacturer as acceptable.

    2 blade ecofan, blades moving slowly at higher temps, metal strip on bottom curling. have wiped off blades and dental flossed the spinning bar for blades.

  • dfve Feb 18, 2008

    same problem. Ecofan rep said lifespan is only 3-5 years! I'm tring to fine thermoelectric module online to replace and also motor. Big bucks for such a short lifespan!!

  • Anonymous Dec 12, 2008

    it's a poor product which doesn't seem to last beyond the one year warranty...i have the same problem after about one winter...slow spin..pretty expensive for one year.

    my ecfo has stopped working are there replacement parts out there?

  • tman152 Dec 23, 2008

    My 802 was going on its 3rd winter (only gets used a few months a year in

    Georgia) and its blade spins only slowly or not at all with raging fire in woodstove. I emailed the manufacturer and they (he) suspected the motor was going bad. He gave me no details yet regarding troubleshooting specs.

    It can only be the motor or the peltier power module. Without specifications I can't zero in on the failing component. Manufacturer said there were spare parts but did not have the presence of mind to include the "spare parts" list with prices. Caframo should do better than this based on the price of these fans. Pretty poor longevity

    Mine's the 3-blade one. Same problem, after 3 years or so. I'll ask them to remove the "Made in Canada" sticker - might as well make them in China if they're this crappy...

  • kkjonesvt Jan 16, 2009

    mine worked great for 2 years. now just sits there. I should have just bought another cord of wood instead.

  • Anonymous Jan 28, 2009

    same problem, 2 years old. Expensive junk

  • msilveira Mar 26, 2009

    same problem here. pretty dissapointed as it was quite pricey to only last a year and a half.

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!

Send me its technical description. It may be due to weak capacitor. Replace it. First check that it is rotating freely by free hand(without electric supply).

    There is no capacitor, just a motor and a peltier device. The manufacturer does not give details of voltage to expect so difficult to determine what is wrong

    Hi I had 3 ecco fans installed 2 yrs ago & just got a call to say 1 fan has stopped working.
    On removal of fan I checked with a 12volt battery & it worked . So I have 2 fans still running & 1 fan that works when put on a battery . What do I need to look at next ? I thought all would be wired up to the same system. PLEASE HELP !

  • Stephen William Lovesy Feb 19, 2012

    Blow off the dust, and spray with WD40. Don't forget WD40 is flamable!

I had the same problem, Ecofan 800 Original was moving slowly.
I tested the motor with a 9V battery to find it was still functional.
I separated the two halves, cleaned off the old heatsink compound and reapplied new compound.
Placed the fan on the stove and it was as good as new!

Fan just quit, replaced motor in early spring so figured it was heat sink. Tested motor with AA battery, worked well. Took fan apart, cleaned heat sink with damp towel, put back together. Works like new again. No cost other than 10 mins of time. Thanks

Mine also stopped so I took the 2 halves apart (black pieces) cleaned the parts, blew out some dust, put it all back together, and right now am watching it spin away, thanks to Nathan's solution.

Cut the wire and hook it up to a dc battery(aa, c or d) and if your fan works it is the
thermoelectric TEG module.
i bought mine off ebay from thermalenterprises. hooked it up and it worked perfect. the are 17-25 bucks
depending on what model you have.

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.

Clean the device

I used an air compresser at 50 psi to blow the dust out of the crevases and then through the back of the fan motor to return the 2 year old unit to like new operating condition.
Hold the blade while doing this so you do not over spin the fan.

I suspect the dust in the motor was sapping the low voltage electricity being generated by the device. House dust buildup causes faults in circuit boards p. Carbon will cause arcing; soot is pure carbon,

Try this before a rebuild.

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.

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.

Have had this for 4 years, works great. Blades have stopped moving though still rotate smoothly by hand.

The problem could be with the thermoelectric module. You can easily test if this is the case by trying to run the fan off of any household battery. If the fan works off the battery then the problem is definitely with the thermoelectric module.

They are easily replaced by taking the two halves of the fan body apart. Just be sure to use CPU heat sink compound (thermal grease) on both sides of the new module before you reassemble the fan.

You can get the peltier modules from Thermal Enterprises by contacting them through email to or searching for Ecofan Repair on eBay. The CPU heat sink compound (thermal grease) is available at any "Best Buy", "Radio Shack" or electronics store.

Hope this helps.

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.
