Bathroom fan drips water


My bathroom fans drip water after a shower. See attached. It drips from the fins. It drips water regardless of weather.

I'm wondering if it's condensation. But it shouldn't be because the fan is supposed to pull the humid air out.

What could it be? Is this a dangerous situation because I have water near electrical lighting?

Most likely condensation----

You need to do several things---

1.run the fan longer---about thirty minutes after you are finished showering.
a timer might be useful.

2.insulate your duct work

3.you may need to reroute the vent so it is shorter or pitched in a way that it can drain out of the building.

Is this the same house with the possible ice damming from your other thread?

as said before need to have insulation on the duct work, second it could be to long of a run at too steep of a angle and the warm moist air cools before it can leave the house. causing it to do that. But like what was said earlier run the fan longer min 30 after you shower.

Yes it's the same house. This can't be related can it?

I'm going to have to pop into the attic to see the duct work. I don't think it's terribly long.

There are some suggestions to insulate the duct work...I'm pretty sure the duct in the attic isn't insulated. I'll have to poke my head into the attic to make sure.

Thanks for the suggestions everyone! If I have problems I'll be sure to post here again.

I had this problem in my house. I had to go up in the attic and make sure my vent pipe was at a better angle because I had ice building up in the pipe because the condensation couldn't escape.
