Re: 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!
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.

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.
It sounds as though the fan is gummed up (a technical expression). Maybe a little fat has splashed on the fan and it's congealed. Try spraying the fan with a little WD40 (dab it off after about a minute) and run the oven until there is no lingering smell of the lubricant.
Yes there is a sequence: 0:00 Dial for fan/limit switch is at 70 deg position. Furnace is cold. I turn T-stat to 80 deg to start furnace. 1:00 Burner comes on and dial begins to move slowly up. 2:30 Dial at 140 deg and fan motor comes on. Dial never goes above 150 deg. 3:00 Burner turns off. Dial slowly moves back towards 90 deg. 4:45 Burner turns on and dial is at 110 deg. 4:50 Fan turns off with dial still at 110 deg. 5:30 Burner off. Dial at 120 deg. 6:15 Fan on. Dial at 140 deg. Burner is still off. 7:00 Burner on. Dial at 120 deg. 7:40 Burner off. Dial still at 120 deg. 8:30 Fan off with dial at 110 deg., and it quickly snaps back to the 80 deg. position. 8:30 plus, cycle continues.....
Running hot at idle is a classic sign of a slipping fan clutch.If the clutch is slipping then it is still turning somewhat and it will stay cool when moving because of the air blowing through when you are moving. Is it completely not turning or turning erratically, slowly etc. If it is completely not turning ever at all there is probably a short in the electronic fan system, or the fan motor or switch is out.
Yes, Massive air flow from the first fan is causing air to be brought in from not only the front of the radiator but from the fan right next to it causing reverse air flow through the fan. This intern can cause less dirrect airflow through the radiator. Also, the recirculation of hot air (from the first fan) into the second fan, across the radiator and back to the first fan can cause the vehicle to run hotter. Wile the car is moving there is enough air pressure from the outside of the vehicle to flow directly through the radiator with little fan assistance needed. If you have the engine running and and turn on the a/c, you should hear the fan change speed or even see the second one turn on (If the fan is working), there is no delay. You might have a bad relay and good fan, as there is a separate relay that activates this same fan for the a/c.
