  1. Hi Everyone, In my new build flat, which is 4 years old I have a Vent Axia Kinetic Sentinel Plus B model installed. In the first 2 years the machine was operating correctly, I usually replaced filters every 6 month, and I had a major service carried out by HRV Group in 2023 September, where they told me the machine is working correctly. During that service I mentioned to them that I hear an unusual sound from the machine, and it got louder. When the technician visited, he told me it's normal. A year almost passed and yesterday on the 6th of June I noticed the machine got loud like an airplane. I have created a video which you can find here: I contacted Vent Axia to ask about warranty, and if they are able to investigate and rectify the issue without any extra costs for me, but no answer yet. My questions are: Is this noise normal with a 4 year old unit? What is the warranty on these machines? What could be causing this excessive noise? Thanks for all the help!
  2. Following on from the excellent post by @DOIGAN where he replaced the bearings in one of the fans from his MVHR, this is a short post to detail the steps to replace the bearings in the extract fan in my Vent Axia Sentinel Kinetic Plus B (being a slightly different model and fan to that of the link below) The process I followed is basically the same as laid out by @DOIGAN in his original post. I've added a couple more pictures and descriptions below. To get at the fans, the unit has to be stripped down. First the duct spigots and blanking plates are removed. Both the back and front covers are then removed, allowing the top and side panels to be taken off - the side panels slide/interlock with the top and bottom panels. You should then have access to the fans on either side which are bolted to the poly core: I then disconnected the power connector to avoid having to try and unplug from the motherboard / cause any other issues. From this point I followed the process as per @DOIGAN Removing the circlip was a bit challenging, as for some reason the hub assembly would not depress, it turns out because the spring beneath wasn't seated properly. I managed to get the circlip off, but naturally it pinged up into the air and I spent several minutes searching for it until finally finding it some distance away. The bearings themselves (one on either end of the hub) popped out easily. I used the same bearings as @DOIGAN Reassembled and back into the MVHR unit. Cost - my time and £7.99 for a pack of 10 bearings vs £298.43 + VAT + shipping charge for a replacement fan from Vent Axia. Vent Axia were unable to give me any detail of the bearings used when I emailed to ask.
