Yes both indoor and outdoor fans will operate, the only time 1 will stop in heat mode is in defrost the outdoor one stops briefly to defrost better,
do you have a heat pump? are you running unit in heat? if so and the steam is comming from outside unit, this is normal in the units defrost cycle
It can, but for safety call or check with the banned that you have
Imagine a window AC unit installed backwards, rejecting heat indoors while air conditioning the world, this is a heat pumps heat mode. As the unit is air conditioning in the cool outdoors eventually the outdoor coil will ice up requiring a defrost cycle, defrost is the AC mode except the outdoor fans off to assist with the defrosting. A defrost cycle is time and temperature initiated, time or temperature terminated.

Ice on a heat pump is completely normal. In operation the heatpump removes heat from outside air and delivers this heat into the home. When the temperature falls below about 45F and the humidity is high enough the moisture condenses on the heat pump fins. The heat pumps have sensors to detect the ice buildup and will reverse every 40 to 90 minutes to defrost the external coils and restore the ability to move air through the fins. If the system runs, builds up ice and does not periodically defrost itself the system is in need of service as the defrost cycle is not being initiated properly.

Your heat pump is going through a defrost cycle.
A HEAT PUMP IS AN A/C UNIT OPERATING IN THE REVERSE MODE. THE OUTDOOR UNIT BECOMES THE EVAPORATOR. THE OUTDOOR UNIT IS MOVING HEAT REMOVED FROM THE OUTSIDE AIR TO THE INDOOR AIR USING THE REFRIGERATION CYCLE. TO MAKE THE CYCLE WORK, WE HAVE TO "EVAPORATE" THE REFRIGERANT AT A TEMPERATURE BELOW THE OUTSIDE AIR TEMPERATURE. THIS TEMPERATURE IS MORE TIMES THAN NOT, BELOW FREEZING, HENCE THE FORMATION OF ICE. OPERATION IN THE "HEAT" MODE, BUILDING ICE, REQUIRES THE USE OF A DEFROST CYCLE TO REMOVE THE ICE EVERY SO OFTEN. LC
