I have a three wire fan, diagram looks like this:
The capacitor swelled but was still somewhat functional so I replaced it, the fan would barely turn.
The problem is I replaced the switch (switch looks like the top diagram, with three pos tied together) and capacitor (except its a purple and yellow wire cap with a value of 1.5 and 2.5uf, now the fan won't turn. But it does get hot (like 110C hot). The hot wire reads 120V at the switch, I can't really measure the other points because of difficulty of reaching them with the meter probe.
I am thinking that the coils could be out... I get 70Ω across the main winding and 150Ω across the secondary of the motor. What could be the problem?
