Bard CMA-39 - Low ambient fan cycling control kit

Bard part number CMA-39 is an OEM Low Ambient Control (LAC) fan cycling control kit used to help Bard wall-mount air conditioners operate in cooler outdoor conditions by cycling the condenser fan to maintain proper system pressures and stable cooling performance. This field-installable control is intended for R-410A refrigerant systems and uses a pressure sensor on the suction line to monitor low-side pressure, with control action typically beginning as outdoor temperatures fall into the 65 to 50 degrees F range. CMA-39 is commonly applied on Bard wall-mount models such as W12AB, W30AB, W30LB, W36AB, W36LB, W42AC, W48AC, W60AC, W72AC, W3SAC, W4SAC, and W5SAC, and it is a solid choice when you need dependable OEM control and correct fit without guesswork.
