If HP, LP, overloads, and oil pressure switch are open, which device is still likely running?

Explanation:
The outdoor compressor is protected by high-pressure and low-pressure switches, the overload, and the oil pressure switch. If those protections are open, the compressor won’t run. The indoor blower motor, controlled separately by the thermostat, can still operate to circulate air even when the outdoor unit is shut down. So the device most likely still running is the blower motor.
