Topaz2008 0 Posted November 4, 2010 I have the common problem where my blower fan will only work on speed 4 and have replaced the thermal overload on several occasions now (as shown in the Wiki). The problem now is the overload does not last, sometimes it will last days and other times weeks :mad2: . I have tried using a slightly higher temperature overload and attaching the replacement using terminal block in case the heat of the soldering iron is damaging it but it makes know difference. Any ideas :scratch: Quote Share this post Link to post Share on other sites
hombre_paulo 0 Posted November 4, 2010 The bushes in the motor will be worn causing it to draw extra current. I had the same with mine and when it gets to that stage your best bet is to replace it. Quote Share this post Link to post Share on other sites
