If the indoor unit blows air but the outdoor unit does not run, the air conditioner cannot remove heat properly. The fan, capacitor, compressor, control signal and power supply all need attention.
Continuing to run the system without cooling wastes energy and can increase stress on key components.

It is not recommended. If there is no cooling, the system may be running without useful operation.
No. Fan, capacitor, relay, control board and power supply issues can create the same symptom.
No. Outdoor electrical components require safe testing and proper tools.
