Product Details

The Suburban 233383 sail switch is a critical safety component designed for Suburban RV furnaces. This replacement sail switch monitors airflow within the furnace system, ensuring proper combustion air is present before allowing the burner to ignite.

Key Features:

  • Direct replacement sail switch for Suburban furnace models
  • Monitors airflow to ensure safe furnace operation
  • Prevents ignition without adequate combustion air
  • Factory OEM part for reliable performance
  • Essential safety component for proper furnace function

Compatible Models:

  • Suburban SH-35 Series Furnaces
  • Suburban SH-35F Series Furnaces
  • Suburban P-40S Series Furnaces

This sail switch detects when the furnace blower creates adequate airflow by using a small sail or paddle that moves with the air stream. When sufficient airflow is detected, the switch closes and allows the ignition sequence to proceed. If airflow is insufficient, the switch remains open and prevents ignition, protecting against incomplete combustion and potential safety hazards.
