[@danielklinker622]

I just bought a house built in 2016 and the grill was so full of dirt I took it down to clean it. It was a complete mystery why it was running continuously at the low speed. I thought maybe it had a humidity sensor that wasn't working. I started searching the internet and your explanation and was the best and most complete. Thank you for the peace of mind, one more thing I don't have to fix. One of these days I will have to climb into the attic to check the fresh air intake, my HVAC air handler is in the attic.

Thank you very much for this video. It was extremely helpful

[@misoudeweese7209]

Thank you for the info! The issue I have is when the a/c is on, the exhaust fan is on, so the cool a/c air is being sucked outward and not really cooling the bathroom. After I turn the a/c off, a couple of minutes later the exhaust fan also stops. And when I turn the a/c on, shortly thereafter, the exhaust fan kicks in.

[@BJPoznecki]

That’s strange. I’ve never seen that before. The only thing I can think of is they may require that were you live.

[@troya.crouse8342]

We have a fan that wasnt always on and yesterday it came on at full speed and wont turn off.... just bought the house in June and this is new to me.

[@BJPoznecki]

It’s possible the switch to turn the fan on and off may have failed and needs to be replaced. For your situation, I would call an electrician to come and help out.

Thanks so much!!

[@ConnieT994]

thanks i saw the switch off just had it installed didnt know if i should leave it off or leave it on

[@ssathue]

Is it possible to turn off the fan completely (i.e. so it does not run continuously)? I was unfortunately talked into installing two of these Broan fans in my master bathroom (to replace the two old-style fans from years ago), so with both of them at the lowest setting of 30CFM my overall minimum for the room is 60CFM and I really have no need for that much continuous exhaust. So I'd like to prevent one of them from continuous operation. Thanks for any advice and thanks for your instructional video! 🙂 p.s. On a somewhat related note, continuous exhaust also continuously exhausts heat from the room too, yes? That's not so great for northern climates like Maine where we need to heat the room (and house) for extra months. Nobody seems to mention that aspect in anything I've read so far online. Thanks again.

[@BJPoznecki]

Thank you I’m happy to hear you like the video. Yes, an electrician can wire them differently to where they act as a normal exhaust fan that turn on and off with the switch, and does not continuously run. Unfortunately, it’s not something I can walk you through, you’d have to have an electrician open up the fan and rewire it accordingly.

[@TheNageenabashir]

I have a question. I have a pull string extractor fan on my bathroom wall, not ceiling but it continues to run 24/7. The string does not stop it. It has no.timer or a humidity sensor. It's all wired correctly. We have switched off the whole electricity supply to my apartment, the only thing that continues to run is the fan. How is this possible without any electricity supply and why can't i.turn it off?

[@JacksOLantern]

Thank you so much man!

[@xKapnKrunch]

I know this is a really old video. I just moved into an apartment and i haven't pulled the cover off. Yet the switch on my wall is a push button and sensor I think. It keeps turning on by the switch to its full running speed. Is this a moisture thing? It's raining outside but haven't used my shower today. I noticed when i used my shower the light on the switch turned on. Its been all day even when click the switch. Hours later it will be on again full bore.

[@BJPoznecki]

I’ve seen so many different ways of installing and wiring bathroom exhaust fans that I couldn’t tell you on yours. I would just ask the property manager at your apartment community how it works.

[@xKapnKrunch]

@@BJPoznecki ha ha I appreciate the response it does appear to be moister sensitive. It was on all day when it was raining outside and it's off and on during the day. (The ramped up speed) that you can hear from anywhere in the place. It's mostly off. Though so not an issue it was just my first full day in the house and I was like wtf. I don't like this 😂.

[@WilliamE..]

We have a fan that stays on all the time, and vents out through the roof, it has a light, and the switch on the wall turns the light on and off. It's was installed in 2013, and only occasionally makes a little noise, but usually it's quiet. I was thinking about going up in the attic to try and clean it, but I'm afraid since it's run so long if I shut the power off, it might not come back on.

[@peterbenson2287]

helpful video. thanks. question: is setting the fan to run at a higher CFM more helpful? Ours was set to run continuously at full speed - not sure if that was an oversight or somehow more beneficial. (It's certainly noisier!)

[@BJPoznecki]

It was an oversight. We want it to run at full speed when somebody’s in the bathroom. However, when you turn it off, we want it to drop down to just a slow speed.

[@alexandrosmakridakis6992]

What are options for a continuous exhaust fan ??

[@pacebo1948]

Well done video and very helpful. How much electricity is being used with the fan continuously running. Electricity in this country is very expense compare to Spain, even though in the past year electricity has risen.

[@BJPoznecki]

Thank you! I couldn’t tell you for sure how much electricity it draws, however it should be very little because the fan is moving at a very low idle speed.

[@hdhoman2832]

Can the fan be turned off? I just moved into brand new construction (apartment) the fan is in kitchen/living area and the insulation is getting blown onto floor Also have noticed all my granite countertops are dusty even though I clean daily, it must be coming from the ducts

[@BJPoznecki]

@@hdhoman2832 It sounds like something might not have been installed correctly. I would call the Builder.

[@Rochelle-ph5yo]

I have one in the hallway as well near HVAC. And the switch does not turn my running Ac off. You're thoughts

[@BJPoznecki]

The one in the hallway could just be an exhaust fan to remove air from that area. Sometimes I will see them near laundry rooms, where the washer and dryer are.

[@vfernandez6454]

I just noticed our fan is on more than usual or feels louder than usual. Does it mean something at all? I keep trying to turn it off but it keeps turning on.

[@BJPoznecki]

More than likely, it’s a continuous running fan like you see here in the video. The only way to know for sure would be to take the grill off and see if you have the adjustable dials like this fan has. If you don’t, there’s a possibility it may not be wired correctly, where it is always on. At that point you would have to have an electrician take a look at it.

[@kevinsorensen367]

I understand the use for new continuous fans. But I'm looking to fix my issue with the old standard switch fan that stopped responding to the switch one day randomly.

[@BJPoznecki]

You’ll have to process of eliminate it may just be simply replacing the switch as it may have failed, or the fan motor needs to be replaced. I would start with pulling the switch out disconnecting one of the wires on the switch and touching it to the other wire to see if the fan turns on. If it does then just replace the switch. If it does not then it’s something with your exhaust fan. At that point your best bet would be to have an electrician come in to repair or replace.

[@savannahbrown5722]

Does leaving the bathroom door closed make fan stay on? My fan constantly runs even with switch off.

[@BJPoznecki]

Hi Savannah! No, the fan is wired to continuously run. Opening or closing the door has nothing to do with it. If you don’t want it to continuously run all the time, you would have to have an electrician wire it differently.

[@jimmyh1578]

I HATE those v-clips, you make it look so easy!

[@BJPoznecki]

Thank you! They can be tricky little bastards 🤬🤣

[@Rochelle-ph5yo]

Should the fan in the bathroom constantly run or should it always be left on and what does the fan actually do. Does it somehow get rid of toxic air

[@BJPoznecki]

If you have a continuous running fan like the one in this video when you turn the switch off, the RPMs drop to a really low idle to where it never fully turns off. What it’s doing is creating air circulation throughout your whole home.

[@lallie61]

Is there a way to shut it down and convert to manual on and off switch. Or that’s illegal?

[@BJPoznecki]

Yeah, however to do that it has to be wired differently, so I recommend hiring and electrician.

[@kathrynreed8851]

The fan in the laundry just today has been on for hours. This is the first time. It has come on for short bursts before, but has never run for hours. Should I be concerned?

An electrician installed a Broan lighted fan in my shower this week. There is no connection to my furnace as I have forced hot water heat. He screwed up and when you turn the fan switch off the friggin thing keeps running. No bueno. He was sub contracted via another contractor that’s doing insulation in my house so I had them unplug it for now but looks like they will need to get the electrician back here to fix the issue. Too bad for him. Do it right the first time.

[@TheNageenabashir]

I have an issue with my extractor fan. It wont turn off. It is a pull string one. It runs 24/7. Ots wired correctly but we cant stop it from running. Its on the wall in my bathroom. We have turned off all the electricity supply to my apartment and the only thing running is that fan, without any electricity supply. It dosnt have a timer or a humidity sensor, nor does it run off the light. How do we turn it off?

[@BJPoznecki]

So, a lot of condo and apartment buildings have a building controlled exhaust fan in your bathroom so there’s always fresh air moving through your unit. Unfortunately, to my knowledge, you can’t turn it off other than if you pulled it apart and were able to disconnect the wires. However, I wouldn’t do that if I were you because it’s very important that there’s always fresh air moving through your unit so you don’t get any mold or mildew buildup.

[@TheNageenabashir]

@@BJPoznecki thank you. Might explain why we can't turn it off, just find it weird that it runs on no electricity

[@BJPoznecki]

@@TheNageenabashir A lot of the ones that I’ve seen there’s a central fan that powers all of them somewhere in the building. It creates a vacuum pulling the air out of your unit, into the system, and exhausts it out of the top of the building.

I have a Broan exhaust and my home was built in 2020. The dials are not on my exhaust in the ceiling and there is nothing that gives me the model. Any suggestions on how I can turn off my fan and turn on when needed?

[@BJPoznecki]

Well unfortunately I’m only familiar with the one in the video that the builder I used to work for installed. All I can say is check the inside housing and see if there’s a cover panel that needs to be removed to access the dials? There should be something where the wiring is. If there aren’t any dials I would get an electrician to help you. There’s gotta be a way they can wire it so it just turns completely off with no continuous running.

[@davidzip873]

In the case of my house, I have a humidity dial in the fan circuit. If it’s set too low the fan stays on.

That’s great idea! Thank you for sharing.

[@meiryedilla]

Mine is the same brand as you showed, so if this one is supposed to always be on, why does it have a switch? lol does this use a lot of energy? I was trying to turn it off to save energy, what do you think?

[@BJPoznecki]

No, it’s not supposed to turn off when you turn the switch off it’ll run at full speed for whatever the timer set at and then it will drop down to a lower RPM whatever that setting is set to. When you turn to switch on it, kicks it up to full speed. The energy it uses is so minimal you won’t even see it on your electric bill.

Hi. Thank you for making this video. My home was built in 2015. The exhaust fan in my upstairs bathroom has been running continuously for about 5 days now. I’ve lived here since the house was built and I’ve noticed the fan running before without the switch on and it’s been a softer quieter sound. Now for the last 5 days, it’s been a louder almost annoying sound. What condition does the environment have to be before it shuts off? Ironically, my daughter says she heard something crawling around in the vent about the same time the fan started running continuously 🤔

[@BJPoznecki]

My pleasure Angela! The fan has no correlation with the environment typically there is a timer that when you switch the fan off it runs for a set time depending on what the electrician that installed it said it too. At this point it’s too hard to diagnose what’s going on especially if a critter is up there and maybe they chewed on the wiring and somethings failed. At this point I would call an electrician to come in.

[@精萃篇]

So we should let the fan on 7/24, 365days ?

[@BJPoznecki]

Yes, that’s per design so there is always positive airflow through the home.

[@bradley7506]

@@BJPoznecki hi, what is the benefit of positive airflow....especially in our cold winters here? Is this to bring in a little humidity? I ask because our humidity in our condo is never more than 30% in the winter. The secondary bathroom fan switch (in the laundry room) was not working anymore so I disabled it but I guess I should buy a new one and install it. Will this draw some humidity in from outside if I replace the switch?

[@BJPoznecki]

@@bradley7506 Hi Brad! Now days with new energy building codes in place the buildings and homes we are building are much tighter where there is less air flow throughout the home, so municipalities are requiring it is continuous running fans to be installed. In regards to the 30% relative humidity in the condo. It’s funny you should mention that I literally just shot a video (not uploaded yet) on whole house humidifier‘s as I just installed one yesterday for my girlfriend at her condo because it’s really dry in the winter time. So, if you’re looking for more comfort and to add moisture to the air I recommend installing a whole house humidifier on your heating and air conditioning system.

You would need an electrician to wire it differently.

[@sanchez831tech]

bro you think this consumes alot of electricity?my bill is high all 5he time

[@BJPoznecki]

Na, as long as it’s running at the slowest speed you can set it to, it’s a very minimal cost. Typically higher voltage mechanical systems impact your electric bill such as your air conditioning, electric ovens, electric heaters, etc. This thing is like an LED light bulb it’s nothing. For maximum cost savings I would turn it to the lowest RPM setting, and turn it to the minimum time delay setting so it goes back to that idle speed quicker after you turn the fan off.

[@roadassassin9445]

My fan continues running when the switch is off my bathroom does it I want to fix that problem

[@BJPoznecki]

It’s supposed to keep running that’s done by design. If you want it to turn off completely when you switch it off, you have to wire it differently up inside the fan. You may need an electrician to help you on this one if you’re not comfortable with electrical work.

[@mallorysiniff6729]

Isn’t this a fire hazard that the motor is running ALL the time?

[@BJPoznecki]

No, it’s no different than a radon fan motor running all the time, or switching your furnace is blower motor to the on position, etc. It’s needed because with the heating and air-conditioning system bringing in fresh air we need a way to remove air already within the home.
