hi. I have a 1 year old home, and my gable fan (actually, it's attached to one of the walls of my home, in the attic, is not working properly. it's set to come on when it gets to be 110 degrees up there, and it's coming on, but it's pulsating. essentially, when it's on, the fan speeds up and slows down. no, there's no wind's been doing this for the past week or so. i checked the wires, and from what i could tell, the connections are not loose. any ideas of what it may be, and how i can fix it? thanks for your help.

Is there also and intake vent or vents by which fresh air can be drawn into your attic?

If not the pulsating may be coming from the vacuum caused by there being none.

It could also relate to thermostat on the fan which may be sensing the motor overheating to compensate for this lack of intake ventilation.

yes, there are two vents. one is just in front of the fan, so it can push the air out. there is another vent on the other side/opposite end of the attic, but it's about 30 feet away. do you think that might be the problem?

this pulsating is recent, with the constant 95 degree days we've been having the past 3-4 weeks. before that, the fan used to run, when it was 80 degrees out (but still 110 in the attic), and didn't make the noise.

i went up in the attic and tooled around a little bit, and found out that the 2X4 that the fan is rigged to was/is vibrating and thus causing the noise.... couple of nails and it's a pretty simple fix. that's for help with troubleshooting.

on another note, i honestly don't know if the fan helps cool the house. i mean, i'm sure it clears out some of the hot air in the attic, slowly but surely, but A) it's still a furnace in there and B) my AC bill is still pretty steep. any idea what the scuttlebutt is in terms of the fan actually helping the bottom line? thanks.

Some study with the pancake roof vent fans have shown that they can depressurize the attic.

That cause conditioned air to be drawn out from the house through gaps in around pipe,s wires, etc.

That then unconditioned air to be drawn into the house from the outside where it has to be cooled and dehumdified, just to be cycle back out the attic.

If you have FG insulation look for dirty places. Those are places where the FG is actign as a filter, filtering the air from the house.
