1620 CFM Black Electric Powered Gable Mount Electric Attic Fan

This redesign has the cable exiting the motor near the bottom rather than the top which limits how far to the left that controller may be mounted causing it to overlap the opening. So the humidistat is sampling the outside humidity causing the fan to run during the night which it never did before with the older design. No instructions were given on how to modify.

This unit was a direct replacement for the unit purchased 25 years ago. The new unit had a humidity option along with the thermosensor. The only issue was the motor was not centered so after the installation the fan blades struck the housing causing a blade scraping noise. Was able to make some modifications and all is well. Suggestion for inspection prior to installation to ensure the fan blades struck spins without obstruction.

Stamped production date on my WCGB fan is July 2022. It was installed in October 2022 and the temperature was set at 100F. Thermostat cycles properly but the fan blade does not move freely and bearing is seized. Customer service said the warranty is not applied since I don't have the purchase receipt and they cannot verify the exact time of purchase/installation! The warranty clearly states 5 year Replacement Plus protection but the manufacturer does not honor their own stamped date!

I liked the fact that HOMEDEPOT.COM included installation instructions on the product site. It really helped me with ease of the installation. The fan works very well and is quieter than others I have seen. The thermostat works right on que.

My attic has plenty of ventilation holes, but it's still like 30+ degrees hotter than ambient air on a cool day, so I figured I'd add a fan to improve the situation. I chose this model because it's advertised to be quieter and more efficient. I can't confirm or deny that, as this is a new installation and I have nothing to compare it to. I didn't have any plywood lying around to make a proper mount as instructed, so I quickly threw together a frame out of what I had laying around before things got hot up there. If I'm feeling ambitious, I may build a proper mount with plywood and add some kind of vibration dampening material between the frame and the house. Maybe that will improve the noise and/or efficiency? How does it perform? Noise: I can hear the thing running from in the house... even on the other side of the house. My wife described the sound as "soothing" and you do generally forget it's there. My attic has what I assume is mediocre insulation, so it's not like there's nothing to dampen the noise. Power Consumption: The specs say this thing should take 160 watts. I've got mine temporarily wired up to a smart socket that monitors power. It's consistently pulling 200 watts. That could have something to do with how it's mounted. It's supposed to be mounted to a circular hole, and the instructions say it should be 3 inches from the louvers. Mine has neither of those things going for it. Performance: It seems to be doing the job. I can go outside and feel the breeze blowing down from the attic (the louvers point down.) It's been relatively cool outside since I installed it, but I think it's kept the house cooler than it would have been without it. Enough that the A/C never kicked in on days when it would have otherwise.

What I like about this fan: 1. It comes with a connected thermostat so installation wiring is simple 2. It was the right size for what I need. (it matches my gable vent size nicely) 3. It is not very loud. I wired it up to a cord and did a test run. It is pretty quite for what it is. 4. The flow seems appropriate for what I have in mind and the thermostat adjustment is easily accessible. I still have some work to do in my attic to get up to the gable and get it installed (my gables are very high so I have to build a ladder and a platform from which to work.) but I have rounded up most of the materials I need and have a plan now. I will probably get a qualified electrician to wire it off a dedicated breaker especially since my box is a short run from where I will install it. I live here in the south and the heat in my attic in the summer is super intense by this time of the year (June) even with a ridge vent. I think this will help move some of that hot are through to supplement the ridge vent nicely. My plan is to put it on the sunniest side of the house so that it will pull from the other cables more on the shady end of the house in addition. My soffit is only partially vented and I may eventually have it all replaced so that it is all vented. I think this will help until then and in addition to that when I get around to it. I’ll probably set the thermostat above the default setting since 105 is a cool day in my attic and I would rather it not run continually. But that is something that is super easy to adjust to my liking once it is installed. There’s a template on the back of the box to facilitate building the frame to mount it. I mounting mine on 3/4 plywood with a 2x4 frame on the back of that to wrap it in against the cable and help direct flow.

The thermostat did not work properly, fan was turning on and off at all hours. Extremely loud, and vibrated the wall. Should have realized the four open a returned boxes that were put back into inventory for sale was a red flag. Home Depot took the Iran back without issue, however had to pay the Handyman to return and uninstall.
