Why is my heater blowing cold air after power outage?
Power outage surges can cause the capacitor to fail. If the capacitor blows during a power outage, the compressor will not come back on once power is restored. Therefore, the outdoor unit does not work to perform heat exchange, yet the indoor unit operates normally.
