Frost on the suction line indicates that its temperature is:

Above the dew point
Below 32 degrees Fahrenheit
Below ambient temperature
Above 32 degrees Fahrenheit

The correct answer is: Above the dew point

Frost on the suction line typically indicates that the temperature of the suction line is above the dew point. When the surface temperature of the suction line is below the dew point temperature of the surrounding air, moisture in the air will condense and freeze on the line, forming frost. This is a common sign of improper refrigerant levels or airflow issues in the system, leading to the temperature of the suction line being above the dew point temperature.
