Questions & Answers

How dose the thermostat work

Asked by: Jojo
The thermostat does not display any obvious numbers (such as 78F). It's a blind dial that you adjust by "feel" so that as you play around with it, you'll eventually get an "idea" of where your comfort level is, and then you leave the dial in that position. So let's say you notice you feel comfortable, you will slowly turn down the dial until the fan stops. Leave the dial EXACTLY at that position, and the fan will only turn on once the surrounding temperature exceeds this point. I personally do not use the thermostat function, and I just leave the dial turned all the way to the maximum setting so that the fan always runs.

Weather-Shield Select 20 in. 3-Speed Box Fan with Thermostat is rated 4.7 out of 5 by 33.
Rated 4 out of 5 by from 4 Star Review Rating provided by a verified purchaser

Rated 5 out of 5 by from Best for price and category I always recommend paying just a bit extra cash for a 20-inch box fan. Not only does Lasko build the best ones in this category, but the Weather Shield pushes more air and has a stronger motor than units which cost a few bucks less. Makes for a great room fan, window fan, or even as the perfect 20-inch fan to build your own air purifier (which is exactly what I did with this fan model, four AC filters, thick poster boards for the bottom, and a bunch of masking tape.) I am happy, and it was well worth the wait, since most places were sold out of this unit. Keep in mind that the Weather Shield does run a bit louder than other 20-inch box fans, but it does not bother me. I just let it run at the lowest setting for my needs, and I quite enjoy the "white noise" as an extra bonus at night!

Rated 4 out of 5 by from Powerful - does what I *expect* a box fan to do I was very impressed with this fan (which I chose due to so many glowing reviews). I have previously used cheap box fans from discount stores, which seem to barely stir the air. This fan is well worth the few extra $, due to its power. On high, I can feel the air flow at about 15-20' away. It's not silent, but the lowest setting is easy enough to ignore at bedtime. Works fantastically as an exhaust fan, as well. I'd like to give it 5 stars, but the power/speed knob shorted out after 3 weeks, during which we mostly ran it constantly - turned the knob *maybe* a dozen times. I'll be exchanging it for another of these, tomorrow. (Since I've seen no other reviews mentioning the knob issue, I'm sure it's just a random defect.) All-in-all, this fan makes a huge difference in an un-airconditioned apartment, whether pulling in cooler air at night or pulling out hot/stuffy air.

Rated 5 out of 5 by from much better than standard box fan The "sealed" fan was found on net by accident. I bought it for extra safety in two windows (blowing in-blowing out). It is obviously higher quality than the standard Lasko good fans I own around the house. It is heavier, more attractive, and the thermostat is much handier than expected i.e. if it gets much colder during the night it will shut off with freezing out my bride.

Rated 5 out of 5 by from Great Fan! I love this fan! I use this for a soft noise at night, it moves air wonderfully too! The thermostat will turn the fan off when it gets too cold which is really nice on cool nights! The fan sits in my window and a couple times it got rained on. (oops) I glad the weather shield has kept my fan running smoothly! The fan even looks nice with the stainless steel sides!

Rated 5 out of 5 by from Great Fan High Quality I have several "turbo" fans that had disappointing air flow even on the highest setting so I decided it was time to replace the box fan that had stopped working last year. My local store only had the version with the thermostat in stock so I decided to try it. This fan is a much higher quality than the last lower end lasko fan I had that started to fall apart and after the feet broke it wouldn't stand up. This fan is sturdy and stand up on it's own without the "feet" that you are suppose to put on the bottom. The feet seem worthless so I left them off since they make it impossible to put the fan in the window sill to pull hot air out. The documentation say this has a sealed motor so bad weather will not damage it. Overall it is a much better quality fan than the lower end version of the same brand, and really pulls cool air in or pushes hot out extremely well without blowing you off of your feet. Far superior flow than my "turbo" fans. The three speeds are the perfect you can blast it on high or get a nice lower, but still adequate, flow. I set this one up in the bedroom and it keeps the room noticeably cooler than the front of the house so I'm headed back for another. If my store had the version without the thermostat I'd buy that since I don't really see the need at least on a box fan.

Rated 5 out of 5 by from Best Box Fan! Every summer, we buy a box fan, because it's cheap, and with lots of dog and human hair, we expect it to get gross. So often the box fans can't keep up with our cooling needs, but this one actually does! It's a stronger motor than other box fans and its high setting seems significantly higher! We often use it on the medium setting because it's too cold! We loved this fan so much, we went back for a second one. Well worth the money!
