Shutting off the power to the condensing unit will involve locating what's called an electrical disconnect switch and turning off the 240 volt power at that point. The disconnect is a weatherproof metal box located near the condensing unit.
To turn the power off proceed as follows:
- Open the disconnect switch box and depending on its design, remove the power plug which activates the box, or turn off the power with the shutoff handle or remove the fuse plug.
- Also turn off the power to the unit at the main electrical service panel.
- Wait a few minutes before proceeding with any further maintenance steps. This will allow any stored electrical charge that may reside in the unit's capacitors to dissipate.
