Hi, I'm working on a fan motor, installed in a SAVE VSR 500 heat recovery unit and the circutboard inside the motor have some blown components. Amongst others, a component marked "CFW" and the number "62" on the vertical.(attached pic) It is a SOT-23 component and I'm having trouble finding information or replacement for this one. On s-manuals.com I can find the "CFW" component, but it's a WSON8 2x2 (8-pin) batterycharger. That's the closest I've found so far. Some "CF" components can also be found, but not sure which one is the right one.
The heat recovery unit consists of two similar fans, so when testing the other fan (the working one) I get the following readings:
On the picture I have marked ground/and minus on a larger Capasitor (C) which is connected to pin marked "1"
Doing a diodetest (in circut) between 1 - 2 = 0,601V
Between 1 - 3 = 0,819V
Between 3 - 2 = 0,824V
Does anyone have som usefull information to share, to help me out?
Thanks
