Which risk increases when a refrigeration system's capillary tube constricts?

💡 Explanation

Motor overheating increases due to higher compression being needed because the lower refrigerant flow means increased duty cycle—the isenthalpic expansion cannot occur efficiently. This causes excessive work from the compressor motor, therefore overheating becomes a risk, rather than proper cooling.
