Probably could've also test if power is going to the motor from that big chunk of pcb. That has a dozen parts that can fail more easily than a simple electric motor.
4” fans the Bain of my life, I’ve installed cheap and expensive ones..they just don’t last very long, I tend to stick the turbine looking ones in the loft if I can get away with it.
Fans should be regularly vacuumed but that never happens.... You would normally find in bathrooms the air and dust and water creates damp dust that gets attached to the fan over time and clogs, causing it to work harder and induce wear and tear at a rate quicker than normal... only a good quality fan could last longer... combination of mass production and less quality control is the cause.
@@dfgdfg_ Anything that does not have a chinese motor, maybe Legrand.. schneider electric or xpelair. but could still be cheap motors in them or maybe not.
Perhaps no backdraft shutters fitted? If the motor is having to work hard when the wind blows back into the ducting perhaps it's shortening the life of the motor?
Those vent axia fans tend to fail after a while, tends to be a small capacitor that goes on the circuit board. Two failed in my flat within 6 months of eachother!
yes your right av had this problem as where the branch in the ducting was connected it was chocka block full with crap ! i.e y joint it was also flexi duct stuff i hate that stuff on fans
I’ve fitted hundreds of these, not a bad fan but there’s far better ones on the market. Fitting fans in a ceiling is always best to avoid as a lot of sparks don’t use the correct ducting and duct it too far to have any effect. I’ve got a garage full of theses things where moistures dripped back in to the fan and fryed it. Not the best design. I’d. always core drill out or if not possible use a in line centrifugal fan with insulated ducting.
I got called out last week to a new build, the homeowner was getting belts off their oven, who ever installed the electric didn’t think they needed a CPC for the hob so just chopped it off, was getting 180v on the metallic surface of the oven to the earth of the kitchen ring main.
Got a shock off my sister's Lamona glass induction hob. Spilt a bit of liquid next to it on the laminate worktop and wiped it with my wet hand, and accidentally touched the metal cooker door below with my other hand. Measured up to 122v. I think it was helped by a mass of breadcrumbs underneath the sticky sided glass edge. With the DVM just on the dried wooden top half a foot away, it also measured 2v with the insulated probes held in the air until switched off. Told her to get a spark in and she said "It was fine when I was using it!".
Great video, very informative. I’m having a similar issue but the fan is an in-line duct fan, the biggest issue was locating it under the floor boards 😅
No ones mentioned the IP rating, IP44 when the fan stops there would be a mass amount of moisture on the PCB and within days it will fry, the PCB looks too exposed (china). get one with a better IP rating which would have PCB coating, which that clearly doesn’t.
I've had a few of these fail on the low speed setting, change them to full speed fixes it, suspect a failure on the dropper resistor, but didn't check. I've only had one bearing fail so far, despite some running pretty much 24/7
Probably on too small duct or too long run (or both) and the static pressure is too high - making the fans ineffective and shortening the electronics lifetime.
Never. note it is a fan and not a turbine. There is no physical possibility of building up a pressure in the exhaust air line that would lead to a force feedback. Since this fan is not subject to any measurably higher mechanical stress when the back pressure is too high to build up an air flow, a load-related shortening of the lifespan of the electrical components is excluded. Furthermore, axia-vent specifies these fans in its own data sheets as B and C goods as well as a maximum working time of 2 hours, which means if you forget to turn it off, the fans are quickly scrapped.
These Vent Axia silent fans are very unreliable. I have three in my house and have had to change all of them within two years of installation. All three vent directly out of an outside wall so they are not working hard to shift the air down a long pipe. I love the silent fan, I don't want it to sound as if I have a 747 taking off in the bathroom in the middle of the night, but this brand has proved consistently unreliable. Can you recommend another manufacturer?
I have brought Soler & Palau which are a failry premium brand of in-line fans and they seem to only last 2-3 years before giving up! Built-in obselesence...
I always fit inline fans.look nicer and seem to be alot more powerful.saves core drilling too in most cases.i think thus are usually vent axia or monsoon
If you have kept the defective fans, how about sending them all to Big Clive for autopsy?! It would be interesting to know the problem, especially since so many have failed in a row.
Marcrist ceramic 6mm drill bit. Ruddy expensive but worth every penny. Xpelair silent are my current fans although I have an icon airflow 35 fitted in my bathroom. :) Great video. Cheers.
most of these fans have 3-5 yr warranties. take a picture of back of fan with model number etc, contact supplier/manufacturer and they will post you one for free. as a sparky always take pictures of back and keep broken ones instead of throwing them away, sometimes it's just motor or electronics. if its motors easy swap.
3 years? They lasted a long time, usually after 2 years and 1 month they are scrap (always the same defect, undersized circuitry (operating point at 115% of the component load)).
There’s the problem.. they linked them. One will be fighting the other. Wouldn’t expect them to last much longer than 3 years anyway. Most electrical appliances only come with a 1 or 2 year warranty. How long do people expect them to last.. a car only comes with a 3 year warranty...........
ooooooo my god del i was wearing headphone's while watching this i got my ear's blasted off lol my own fault i suppose? mmmm good luck your right to have advised him that this could happen again
How long should the fan last.Our has stopped working it in the bathroom and goes through the roof.The state of the walls after showers is awful even with the window open it’s drenched
I fit monroe gold fans they last 5 years in public toilets start 7am of 12.30 pm . Need cleaning out every two years. I find its never the motor but the electronics that's failed. Great job again .
Asif Iqbal, I believe YOUR comment has finally solved the mystery of why the top fan was so dirty. Some of the air from the fans on the lower apartments had 'always' been exiting through the top-floor fan via the common duct, an ongoing problem (not a pleasant thought). Presumably some of air in the rising common duct chose the lower resistance path of the top-floor fan rather than moving through the ducting to the exit via the outside wall. My own original wrong thought was the very very unlikely chance that the fan had been running in reverse, thanks for your insight.
Most of these fans require a 3a fuse to protect the internals, they mostly state this in the manufactures instructions. I usually install the click range, 3 pole fan isolator with a fuse carrier.
Nice one Delroy! That is a mystery regarding those fans. Surely they wouldn’t burn out prematurely simply because the ducting was long? 🤷🏻♂️ I suspect that, like many things nowadays, they are only designed to last just beyond the warranty period. I tend to choose Xpelair, although even I have to admit that they are simply not built to the standards they once were. Take the GCX6, for instance. That model can trace its roots back to the 1950s; you still see loads of old style ones in full operation, whereas the new model is just flimsy and built down to a cost. Keep the videos coming Delroy! Best sparky on RU-vid 👊🏼 Take good care mate.
axia-vent specifies these fans in its own data sheets as B and C goods as well as a maximum working time of 2 hours, which means if you forget to turn it off, the fans are quickly scrapped.
Mate the lack of commitment to engineering standards in the modern context is appalling. It’s cheap electronic and mechanical components built for a certain price. I hope to God environmental legislation comes in which mandates manufacturers ensure longevity of their products and allow easier repair. Otherwise the waste from poorly made products is every increasing and is not sustainable.
Good content delroy , all bathroom fans need a good service clean once a year otherwise the deposits on the fan overheats the motors. Some have a thermal fuse in them .
So love all your videos and no disrespect intended but are you actually qualified? Should you ever get a problem issue, pls don't hesitate to contact me. I will sort over the phone 👍
Not surprised they`ve died with that amout of crap in them, Vent Axia used to do a similar looking one with an upfront dust catcher slide out mesh filter. The new "woke" low power motors don`t help to clear the dust up the pipe and just stall with a small build up of dirt.
