Noticed that the timer fan in the loo is behaving strange. Sometimes (rare though) it works fine. Other times it takes ages to come on, like a minute, and switches off immediately instead of running on. I'm assuming this is going to be that the fan electronics have gone wrong and I need to replace it but just wondering if there is anything else i should check? Its a Manrose Gold about 18 months old. Thanks.
1st thing to do is isolate power to fan , and then check supply is dead Remove cover to fan and take a look inside. These fans aren’t mega powerful but do suck up dust and fluff and this can and does build up around the fan blades and motor spindle Spin the blades by hand - do they seem to rotate with little resistance ? If fluffy and gungy, soft brush and ur hoover and give it a clean, see if this improves rotation - with power off Cover back on, power back on and see if any improvement If same as, uv guessed it, more than likely the pcb is knackered. If ur an electronics wiz, you could test components and replace if anything has actually failed (in theory) More than likely, scrap fan and replace with new I’ve recently fitted a couple of vent axia 100mm fans and at least they come with a 2 year guarantee
Thanks all, checked it out and the blades turn freely and the whole thing is free of dust. Think its a replacement job!
