air conditioner capacitors

In order to check or replace one, the power should be shut off. So how long can a capacitor still be charged, while the power is off? Just need to know! Thanks!

The start capacitor in an RV AC unit will discharge to a safe value in just a few seconds after power is removed.

To be on the save side, use insulated long nose pliers to remove the wires and then use a screwdriver or the metal end of the pliers to ensure it is fully discharged.

And I'm curious how you know it's the capacitor when you seem to know so little about capacitors.

Under the heading of Lessons Learned:
Use a test device to ensure that the power is disconnected.
=> This is real important if you are on a roof or a ladder.
The capacitors in a A/C should self discharge shortly after shutdown. => Notice I wrote "Should".
Discharge them in place with the SIDE of the screwdriver or pliers.
=> If you use the working end, they can burn the tool so it is useless in the future.

When I got home I googled and researched, and found out, that often times, that's what goes first. When it comes to electricity, one must be cautious!! So, a 2k2 wire wound ceramic resistor should suffice!!

Thanks a bunch!!

With all due respect sir, apparently you have not comprehended the excellent advice you have gotten here. Use a screwdriver! Why would you want to go to the trouble of putting connectors on a resistor when a screwdriver works better?????????

Yeah.. It's not like you're sticking your fingers in there everyday. Unplug the coach, wait a few mins, short it out, and do whatever it was you were going to do. But it's likely you will never be back in there
