Question about Heating & Cooling

1 Answer

Hi, I have an 1985 Chelsea attic fan. The motor is still working fine, and it is turning the main bolt on which the fan blades are hung. This main bolt turns very fast, at the speed of the motor. The fan blades start slowly, and they used to accelerate to full speed, but now they just stay at a slow speed. What could be the problem? Thanks, Joe

It is the fan clutch. Like in a truck with a full time fan, it has a clutch that accelerates the fan as it is needed. Your clutch on the fan has probably burned out.

Vornado fan Model CR1-0023 , Type 750 I bought this fan used 3 days ago. Seemed to work fine but not as powerfully as another new Vornado shop fan I have. Today the fan blades stopped turning. I can...


I have had the same model for almost ten years, and have had to lubricate it twice - both times when the fan stopped rotating. It's obvious that Vornado never intended the bearings to be serviced, but if you're patient, it can be done. You must remove the front louver section (press the three clips inward gently). Then firmly pull the fan toward the front, off the shaft. Then remove the four nuts on the front of the motor housing - you'll note that the bolts appear to be free-floating, but that allows re-assembly after the bearings are lubricated. When the nuts are removed, firmly pull the front of the motor housing toward you. This may require a firm pull or GENTLE prying, as the rear bearing sometimes doesn't want to let go. When you have the front portion of the housing and shaft out, hold the housing and pull the shaft out of the front bearing. Again, this may require a steady firm pull straight back. When the rotor & shaft are free, you'll need some very fine emery paper to remove the varnish that's built up on the shaft (it's unmistakable where to clean the shaft.) And I never attempt to do anything with the front and rear bearing themselves - too much work, and cleaning the shaft does the job for me. Then clean everything up carefully and lubricate the shaft where it enters the bearings (and maybe a drop in the rear bearing itself.) I use a very fine machine oil that I bought at Sears, but I think any good oil would work. Then, it's re-assembly time - shaft into front bearing, shaft into rear bearing as the motor housing is put back together (lining up the bolts), four nuts on the bolts & tighten (firmly, no gorilla), press fan back on shaft (don't force it too far on - it'll stop when it's in the right place), plug in and check, re-attach front louver (just press - the clips will snap easily into place.)

I just bought a new motor and installed it but now


Centrifugal force.....If you replaced the motor only and not the blades, the blades are likely out of balance or possibly bent. Check for wobble and to see that the shaft is fitting tight inside the blade collar.If there is a bushing on the fan blade or shf itself, check it for play as well

The fan blade came off my attic fan, a Leslie


Slide the fan on the shaft. Rotate the blade so the allen screw is over the flat side of the blade and tighten it down. That's it! Be careful how far you put the fan down the shaft so it won't hit the motor or the fan shroud.

Replace old attic fan motor, or replace the entire fan assembly.


I am assuming you replaced your fan by now. However in the future call Gibraltar Industries, they are the ones who manufacture all fans and motors. My attic motor fan also died and I first called Ventamatic and they wanted $65 for a new motor. I then called Gibraltar and they shipped one our for free. 800-527-1924.

Attic fan stops running after one hour


I need to verify you have adaquate air flow, to cool the motor. If you have a window open, and the crawl hole open is there enough air flow into the the attic? It there is enough air flow and it still stops after about an hour, does this unit have a humidistate and a temperature switch on the housing or extension.
If all the switches are working correctly then I could be the motor overloading/heating shutting down and then reseting.

Dayton Attic fan running backwards


First see if the switch has a reverse position. Sometimes you turn the fan assembly in the frame, sometimes you turn the whole frame around. Take the cover off the wiring compartment to see if there are instructions there. Also check on the name plate on the motor, there may be instructions there. Attic fans are usually engineered to blow out.
