Questions & Answers

Does it have a thermostat that turns it on and off?

Asked by: bill
No but you can add a GE wall timer. Have the line (line from circuit breaker/power source) feed into the timer and the speed control (which would be the load) connect to the GE wall timer. All you have to do then is pick how long you want the fan on and then set the speed. Shuts off automatically. Did that with my 24 inch house fan & works great. Bought new home & going to do the same with this one.

Fan Will not start

Motor just makes noise when the switch is turned on. If I can spin the fan fast enough it will start and continue to run. It is great when it runs but I am the only one who can start it. Not good for my wife.

Can this fan be installed vertically (wall) or does it have to go in the ceiling?

Asked by: FSM
I see no reason why you couldnt put this in a wall, but that is not what it is meant for. The fan is not meant to be exposed to any elements or moisture, but hey, a fan is a fan so why not stick it in a wall? The blades might not be balanced for horizontal use. This was designed to be installed vertically, so you can cram this in a wall, or you can buy a fan meant for wall use and know you will be ok,

6000 CFM 30 in. Belt Drive Deluxe Whole House Fan with Shutter is rated 3.3 out of 5 by 63.

It did take me two days to install as I needed to make some framing modifications to center it in my hallway. I was impressed with the construction of the fan, and the newer all metal shutter with felt edges. Got the fan in just in time for 90 plus weather and cools the house down in about 20 minutes. Open the master bed slider and family room slide door on the other end of the house and can really feel the air flow. I do have a 3 ft x 9 ft gable vent and a 7 ft at peak attic and feel that likely optimized the fans ability to generate substantial airflow. Is a little noisy, but expected such with this type of fan, an only have it on for 20-30 minutes.

I lost the original receipt so I ended up just buying a new fan motor and replaced it. When it is installed, it's not that noisy, though you definitely hear it. After about a year, the noise gets higher. If you want something quiet and reliable, maybe look for something else.

Had to fight an issue in the fan for hours, ended up being a fuseable link on the low speed connection, keep in mind there is not one on the high speed. Once that was fixed the fan is up and running fine but it is very noisy, almost twice as loud as the one I replaced from the 60s. Not pleased.

I installed this Master Flow 30" belt drive whole house fan two days ago and will be - unfortunately - uninstalling it and returning it to Home Depot for a refund. It is advertised as a two speed fan - which it is - but both speeds are high speeds! And both speeds are very noisy. I expected a noisier high speed, but I didn't expect it to be noisy on low speed. Way too noisy to try and go to sleep with the fan on - even at the lower speed. It's like having a freight train outside our bedroom! This fan was to replace a 35 year old attic fan that had two speeds - a true low speed, low volume CFM speed and a high speed, high CFM volume fan - but whose motor finally gave out. We'd put the old fan on high speed (also noisy on high speed) once the outside air temp cooled off in the evening to cool down the house, then put the fan on low speed (and low noise) as we were going to bed to continue to have a small volume of cool air keep the house cool while sleeping. Because this new Master Flow fan is noisy on both low (but not really low) speed as well as high speed, it does not meet our needs. If you are looking for a quiet, true low speed as one of your fan speeds, this fan is not what you need. Unfortunately for me, there was no way for me to find this out until my fan was installed, and now I have to go thru the work and pain to uninstall it and return it to Home Depot. Avoid my misfortune and avoid this fan if need a fan with a true low RPM, low noise lower speed.

Rated 4 out of 5 by from works great.. I did an install from scratch. We recently moved into a 3,200 sf house, and those little window fans simply do not do the trick anymore.. that and we now live in a two story house.. heat does rise I found out. and the upstairs was much hotter than downstairs.. but enough of that.. here is the meat and potatoes.. I first had a hard time finding a good spot to put the fan. It needs to be in a central location upstairs. We have a low sloped roof, and blown in insulation. It was summer when installed. It really was tuff working in a high heat condition trying to find a spot that worked.. I finally did. I cut a joist, and reframed to fit the box fan. No problem. I ran new wires down the wall to a new outlet location near the fan. I did get smart, and installed a timer prior to the two speed switch. I could so see my teens leaving this fan on all night.. and that is not what these are for. I usually leave the switch on high.. and simply push the 10 or 20 minute button on the timer and walaah! The fan actually works great. DO make sure you open enough windows so as to not make the fan work too hard.. you will reduce the life of the fan of course if it is overworked. This thing moves air... a lot of air! whoo hoo! it will actually slam doors to room with open windows, so make sure they are fully open. The fan is actually much queiter than we thought and quieter than the display fan at the store.. not bad :) We love the fan and would definately recommend!

Rated 3 out of 5 by from This unit was a replacement because the origional fan in the house had a burned up motor (actually cheaper to replace the fan than buy a replacement motor). Installation instructions were sketchy at best...even with an existing installation. It took about 5 hours to retrofit this unit to existing installation. It has been installed for 3 days and has good airflow, but I was a bit dissapointed because the shutter has a vibration to it. The fan frame looks flimsy compared to the unit it replaced, but you get what you pay for. I would say for the money, it was to be expected.

Rated 5 out of 5 by from Review of the Master Flow WHOLE HOUSE FAN 30 In. I live in the Lake Elsinore area of Southern California in a 4000 sq ft two story house. The typical climate here is warm to HOT during the day (80 to 100+ degrees) with cooler nights (50 to 70 degrees). Our attic would become heat soaked during the day and retain a temp of about 150 degrees or hotter which would require the use of the AC in the evenings even though the outside air was cool. After some research on the web I decided a Whole House Fan should be the ticket to help minimize the use of the AC. I looked at units that cost as much as $1000 down to units as low as $200. My biggest concern was to utilize a fan with enough CFM to move air in and out of our house in 10 to 20 minutes. Basic calculations suggested that a 11,000 CFM unit would be required. This seemed a bit high to me, not only that I doubt my attic has enough ventilation to flow that much air. I decided the Flow Master 30 inch model 30BWHFS which flows 6000 CFM should be more than adequate. I purchased the unit at my local Home Depot. I had to open the unit in the store because no where on the box or on-line are you given the actual dimensions of the fan frame or louver assembly and I had limited space for the install. The wooden box frame thats attached to the fan has an outside to outside measurement of 34 inches. The opening for the louver assembly will need to be 34 X 28 inches. Its kinda odd that the fan frame OUTSIDE measurement is the same as the opening for the louver. This really isn't a big deal but if the louver opening was a little shorter you could build perfect box around your rafters that would fit both the louver and the fan but this is not the case. Because of the way its made you have to build the rafter frame a little longer than the fan frame and seal the gap with the supplied sealing material. I used 1 x 4s but see no reason the supplied sealing material wouldn't work. The install was pretty straight forward and simple for anyone with basic hand tool skills. If I had to rate the install on a scale from 1 to 10 (10 being hire a pro) I would rate it a 3 or 4. The fan comes with a two speed wall switch and the fan is wired as a two speed unit. A common white and ground then a black for high speed and a red for low speed. Since the size of my house is on the larger end for this fan I wired it to a standard light switch and utilized the high speed circuit only. The louver assembly is very simple. Its nothing more than a gravity type. The fan draws the louvers open and the louver free falls shut when the fan is off. The fan has more than enough power to cool down my house in 15 minutes or so. With several downstairs windows open about 4 inches the flow through the openings is pretty substantial. Like many things noise is subjective. When sitting downstairs this fan is no louder (in fact it might be quieter) than a standard box fan you would place on the floor. Its a touch louder when you are upstairs but not bad at all. I think the belt drive has a lot to do with why this fan is as quiet as it is. All in all I give this fan two thumbs up and would buy another in a heart beat. This of course assuming the longevity of the fan is up to par. Notes: This fan does not utilize the pull chain switch that is on the smaller 24 inch. You must wire it to a light switch. I happen to have one recessed light in the area where I wanted to install the fan. I removed the light and utilized its wiring to power the fan. You need to check the tightness of the bearing set screws and you have to mount the motor and adjust the fan belt tension. When adjusting the belt tension make sure you do not get it to tight. It can be pretty lose and still preform perfectly (its not like the fan belts in your car). You also have to align the pulleys. This sounds like a lot of work but its not and pretty simple.
