Air Purifier Electrical Fault.

Zoomup
I was given a faulty VAX air purifier to repair today. The fan would not turn. The motor would not work. The control buttons did operate and a confirmatory bleep could be heard when they were pressed. Also dim L.E.D.s lit up confirming that the control panel seemed to be o.k. The motor fan did rotate quite freely by hand. No damage to P.C.B. P.C.B. fuse o.k. The appliance is rated at 75 Watts. The 1.5 micro Farad motor starting capacitor was reading very low capacitance. In the pico Farad region. After replacement of the bad capacitor the motor still did not start.


What did I have to do to get the motor working, and why?

    beeps suggest electronics, so there will be a relay or a triac that puts power onto the motor, presumably only when certain other conditions are met, but without knowing a lot more, we are in the dark.  Could be as simple as a cover interlock, could be fiendishly hard.
