I have a rheems ac unit. I am thinking of replacing my ac contactor on the condenser outside though it is still working fine (been there almost 9 years). I understand I must cut off 240 volts and turn off thermostat for it before I start.
My question is whether simply use insulated pliers to pull off all the wires to the contactors (lines and terminals) is good enough ? As on the terminal side, it has connected to a run/start capacitor or should I discharge the cap first before working on the contactor replacement ?
If need to discharge cap, can I do it with all the wire-in-place using a big insulated screwdriver or I have to disconnect the wire first ?
Thanks all so much in advance.
