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 thermoelectrics@aol.com 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.

My stove fan has been getting progressively slower over the past few weeks and I've been concerned because it's only one year old.
I have read the remedies on this website, as a result of which I did connect a small 1.5v (AA) battery to the terminals of the motor and found that the fan rotated fast and freely.
Therefore, the only possible problem had to be with the thermo-electric module. I tried to disconnect the top half of the fan stand., i.e., the bit with the air-cooling fins. (The flat thermo-electric module is sandwiched between this half and the bottom half.)
I discovered, to my frustration, that this is secured by two 'Allen' screws of a most unusual size. (3.5mm). I managed to find a flat-bladed screw driver which fitted the top of these screws and, to my amazement, I found that both screws were loose!
I tightened both screws carefully, by the same increment as each other, so as to keep the top half in level contact with the module. Both screws were really tight when I completed the task.
I then placed the fan back on my stove and I am delighted to report that it is now spinning so fast that it is trying to take off!!
The moral of this story is - check the tightness of your screws!!
Good luck & kind regards, Jimmy.

I have a simplicity 6216 mower. When the blades are engaged they back and forth between being fully engaged and losoing power to where they stop completely even though they are engaged.


It seems one of the idler pulleys have siezed up, or perhaps one of the spindles. Un-tension the belt, and try to rotate all of the pulleys by hand to see if any have siezed up or are binding, as those will heat up under operation and stop, but may rotate stiffly when rotated cold, by hand.

When i try to enage the blade on my poulan xt 38". the lawn mower shuts off and the blades do not work. how can i fixs it?


It sounds like something is not moving smoothly. With all power off, lift the deck and rotate each blade while watching for any binding or seized parts. Check both blades and their bearings, the belt and any idlers or tensioners and all pulleys.

My blendtec blender doesn't blend as well as it once did. The motor seems to be running fine, but I am not sure if the blades are spinning properly.


You have already found what is the problem the blades.
The blades after a lot of working hours with ice they have mainly three problems.
One the sharp adjes have created a lot of teeths and are not so sharp any more so the blending is not smooth anymore.
Second problem they have loose a title so they have move from corect place some milimeters and this change the wave motion and again the beleding is not so smooth as before.
Third the blades are secure on an axis which is located in two bearings which have een wearing out so the rotating motion of the blades again is not so smooth as before.
So if you are not able to fix the blades kit or to find someone in your area to do it profetionaly and cheap one good idea is to buy a new blades kid.
Good luck

Motor base is working and container jar base turns by hand but won't work together to spin blades


Just fixed my blender. Motor was working fine, but the bladea wouldn't turn. I removed the blade piece from the base and tried moving the blades by hand and they wouldn't turn. So, I lubricated the blade at the location where it's supposed to rotate. I kept trying to move the blades by hand and gradually they started to loosen up. All fixed!!! I guess they get stuck after a few years of use.

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.

Exhaust fan has stopped working Need to troubleshoot


Even though this is a pain, I need to suggest that you perform the following:
Remove the microwave from the mounting position as follows:
1. Place a cardboard box of sufficient height to have the microwave rest on it with no more than about a 4-inch drop. Cover the box with a bath towel.
2. Using a power screwdriver, remove the 2 mounting screws located in the overhead cabinet base. (microwave front will tilt down onto the box)
3. Firmly lift on the rear of the microwave to unhook it from the wall mount bracket.
4. Once removed, pull some slack on the power cord.
5. Slide the box and microwave forward (toward you)....enough to see the fan blades
6. Place a small cup of water in the microwave and press quick start (30 seconds)
7 Look at the fan blades. If NO movement, open door. Hand rotate blades a full turn to ensure free movement.
8. Restart microwave. (fan blades move - Yes/no)
If No, check power cable that supplies internal power to fan. Be sure it is connectied.
If yes - but only a slight movement - it is clogged with grease...remove it and spray with lots of Ammonia to clean fan elements. Shake excess moisture off. Retest.(fan blades move - Yes/no).
If yes, reverse removal procedure and enjoy....
If no, Replace fan assembly

Watch stopped while in hospital and now, although running again, has the second hand moving in two second intervals


Some Seiko kinetic watches and other self charging watches do this when the battery is low. If it relies on you moving to keep it charged that may explain why it stopped in hospital. Try giving it a good shake and see if it starts moving smoothly again
