My Jet air filter takes a LONG time to get up to speed. I am assuming that the capacitor is shot. I have taken the blower assembly out of the unit. There is a small capacitor attached to the motor. I have a meter (digital multimeter) but don't know how to check the capacitor to see if it is in fact bad. What scale do I use and what reading should I get ? If it is the capacitor, do I need to discharge it before changing it and how do I do that. Thanks for your help.
