Error 441 — Cooling mode restriction due to low air temperature

What does 441 mean?

The cooling mode operation is being restricted because the ambient air temperature is too low for safe or efficient cooling. This is a system protection to prevent freezing of the evaporator coil.

• Ambient air temperature falling below the system's safe operating limits for cooling
• Faulty outdoor temperature sensor
• System misconfigured for current environmental conditions

Click steps to track your progress.

1. 1

   Check the actual ambient air temperature around the outdoor unit.

2. 2

   Verify that the system's operating parameters for cooling mode are correctly set, if adjustable via the Intesis gateway or Samsung interface.

3. 3

   If the temperature is genuinely too low for cooling, consider delaying cooling operation until conditions are suitable.

4. 4

   Ensure there's adequate airflow around the outdoor unit.

5. 5

   If the ambient temperature is normal, contact a technician to check temperature sensors.
