White-Rodgers 3F01-160 Fan Control

The White-Rodgers 3F01-160 is a heavy-duty snap disc fan control designed for precise airstream temperature regulation in residential and commercial furnaces. Built as a close on rise limit switch, this 3/4 inch SPST flanged mount sensor features a fixed 160F cut-in temperature and a 20F differential, ensuring the blower motor engages and disengages at accurate operational setpoints. This unit serves as a direct Replacement for Therm-O-Disc Style 60T12 (Type 610064), making it a standard component for technicians maintaining high-static forced air systems. The flanged mounting profile allows for rapid installation directly into the plenum, facilitating immediate thermal response times. By utilizing a bimetal disc mechanism, the 3F01-160 provides reliable HVAC blower control without the failure rates associated with mechanical capillary tubes. For contractors, this fixed-setting fan switch ensures system safety and optimal heat exchanger cooling cycles, preventing short-cycling and motor fatigue in demanding heating applications.

• Universal Compatibility: Direct replacement for Therm-O-Disc 60T12 Type 610064, reducing truck stock requirements.
• Precision Thermal Response: The 3/4" bimetal snap disc ensures rapid 160 degree fan activation for consistent airflow management.
• Simplified Installation: Standard flanged airstream mount design integrates seamlessly into existing furnace bulkhead cutouts.
• Industrial Build Quality: SPST switch configuration rated for high-cycle reliability in residential forced air environments.

What is the exact wiring configuration for the 3F01-160?
This is an SPST (Single Pole Single Throw) switch that closes the circuit on temperature rise at 160°F, making it the primary trigger for the indoor blower motor.

Can this be used as a high-limit safety switch?
No, this is a fan control switch designed to "close on rise." A safety limit switch requires an "open on rise" configuration (typically the 3L series) to break the burner circuit during an overheat event.

What is the benefit of the 20F fixed differential?
The fixed 20 degree differential ensures the fan continues to pull residual heat off the heat exchanger until the temperature reaches 140°F, maximizing furnace efficiency and preventing rapid cycling.
