I have two attic fans which do not fuction any more. Each fan has a GE 97F5706 capacitor attached to them. The fans are getting 120v power but don't start. One of the fans was working until I swapped the capacitors to see if that was the problem. Now, neither fan functions. I thought that I might have reversed the polarity of the leads, of the good capacitor. I don't see any indication of plus or minus(power or common), on the capacitor. How can I tell if the leads are correct. The capacitor is 6uf, 370 VAC with a + or - 6% 50/60 Hz. It indicates that it is a DIELEKTROL VI.

 

AC motor capacitors do not have polarity.

I didn't think so, but like I stated, after I switched capacitors the motor that was running also quit. I pulled the motors and got no continuity through the running windings but the starting windings had continuity, so I guess the motors are dead. I did get over 10 years from them so I guess I should not complain. Thanks for confirming about the capacitors.

Almost exactly like these capacitors.
