Condenser control, systems, devices, and methods are described herein. One system includes a number of pressure sensors, wherein each of the number of pressure sensors is configured to sense a pressure associated with a condenser of a refrigeration system, a temperature sensor configured to sense an outdoor air temperature, and a controller configured to activate operation of a number of condenser fans and a number of split valves associated with the condenser based, at least in part, on the sensed outdoor air temperature upon a failure of each of the number of pressure sensors.
