surface mount
A short indicates that one or more of the devices on the circuit have failed short - not necessarily the capacitor. The most common failure mechanism for ceramic capacitors to fail short is mechanical stress causing the ceramic layers to crack and internally short out. Unless you dropped the assembly, I doubt the caps are bad.

How to Troubleshoot and Replace AC Capacitor
If you have a dual run capacitor, use the screwdriver to short the COMMON and HERM terminal and then COMMON and FAN terminals to discharge it. That is how easy it is to discharge a capacitor. Step 5: Disconnect the Capacitor. Before you can disconnect the capacitor, take your time to notice how the wires are connected to the capacitor.

polarity). In the beginning, the capacitor acts like a short to the mains voltage and without the series resistor, an inrush-current of several hundred amperes could flow in the circuit and damage the capacitor or the rectifier diode. To calculate the resistor, we can calculate the inrush current with : i: input inrush,max = V: peak: R: in
