    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!!

    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.

  • Anonymous Dec 13, 2008

    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

  • joelmichaud Jan 16, 2009

    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.

  • Anonymous Jan 19, 2018

    I am "late" to the party but my Ecofan of only 4 months was not working correctly either. I had to "hand start" it. I am glad I found this because I cleaned it and I hope I can get the rest of the winter out of it. Next time? I am going for the cheap Chinese knock-off.....Oh well.

    Well,our ecofan lasted well over ten years maybe close to 15 so maybe justified to buy another but more recent purchasers seem to have less success

    Ours has been going strong for 2nd winter... maybe detecting a very slight squeak, thinking it may need lubrication? Looking for suggestions... Do have a nice penetrating oil from that has neat needle applicator.

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!

    Ths Nathan , the compound did the job. It took more than one fire and I also clean the bottom part of the fan. I don''t the last time she was turning so fast. I have been using this fan for 5 years

    Ok the compound did work for a couple weeks. The fan stopped working and I had to replace the motor ''Home hardware'' 16,00 . Very easy to install

    Really got all the old compound off and I mean all of it, tested on stove top and it took off instantly. Thanks for the heads up, I love to fix things!

    I cleaned the old compund thorougly and put new one on, but it didn't work Do you think it is the peltier element, since it spins slowly now and then?

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 !

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

    If the fan is working from a battery then it will be the Thermoelectric generator (TEG)
    These are available online and not very expensive.
    Do not just spray it with WD40 !!
    You will need to carefully disassemble it, clean everything carefully and reassemble with the new TEG and thermal paste (easy to buy from a computer repair shot)
    NB the TEG must be installed the correct way. It has a "hot side" and a "cold side" usually there is writing on it to help you identify which is which. if in doubt mount it in the same orientation as the previous TEG was mounted.

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

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.

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.

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.

The Tempertuer get hight when i drive slowly

When moving slowly, there is not much air flow through the radiator, an electric fan should switch on and draw air through the radiator when the car is moving slow. Check the fan is working, could be the fan switch that is not working, to prove the switch bridge the wires on the switch and see if the fan comes on, (Ignition on). Check for a live feed at the fan, check the fuse.

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.

Fan just stopped turning, even if the fire is going good, what could be wrong?

Bushings dried out at rotating shaft. Clean and Lubricate with a high temp. dry film lubricant.

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!

Fan wont turn t humms

Might need a little more information, but here goes. If the fan won't turn at all, you need to oil it, if you can spin the fan and then it slowly beguns to run ful speed, replace the run capacitor.


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.

Fan controller does not work! Power Up (TC3J-4048)

It is bad out of the box. either take it back or email whoever sold it to you and get a new fan. You should not have to pay for a new one.
