The building up and accumulating of ice in the outdoor system during the winter season is a major reason for the Samsung air conditioner not heating the home.

When ice builds up in the outdoor units, it restricts and limits airflow. Extreme cold weather causes the condensation in your system to ice up.

Moreover, when the refrigerant leaks from the system, it causes the formation of ice inside the air conditioner.

Dehumidifier inhibits the formation of ice in the unit. That’s how you can solve the Samsung air conditioner heat mode not working issue.
