General Aire 727-58 Transformer 24V
The 727-58 transformer is a device that reduces the incoming electrical current from 120 to 24 volts AC, which is the proper voltage for the humidifier circuit. These transformers are built to perform effectively year after year, but may eventually fail, likely causing the humidifier to stop working. If this happens, the transformer should be replaced immediately.
