No, a residential air conditioning system cannot function or provide effective cooling to your home without a working indoor blower motor. Even if your outdoor condensing unit, compressor, and refrigerant lines are operating perfectly, the indoor blower fan is entirely responsible for forcing warm indoor air across the cold indoor evaporator coil. Without the blower motor running, heat cannot be absorbed from your living space, and the stagnant air inside the evaporator coil will drop below freezing, causing the coil to encase itself in a solid block of ice within minutes. This can lead to severe compressor damage. You can troubleshoot by checking furnace fuses and inspecting motor capacitors. You can verify that the system is safe to operate when power is restored and the blower motor circulates powerful airflow through your supply vents.
