Reznor 146464 Fan Control

When you're out in the field and the unit isn't cycling the blower correctly, a dependable thermal switch is critical. The Reznor 146464 Fan Control is a purpose-built OEM component designed to manage the blower motor cycle based on heat exchanger temperature. Rated at F135-30F, this fan control switch triggers at 135°F and cuts out once the temperature drops by a 30°F differential, ensuring that your system doesn't blow cold air into the space during start-up or shutdown. This specific model is a fan control without bracket configuration, specifically engineered for direct mounting in tight HVAC unit heater applications where a standard flange might interfere with the installation. As a genuine Reznor replacement part, it maintains the precise calibration required for industrial HVAC systems, eliminating the guesswork of aftermarket "universal" alternatives. If you are dealing with a blower that stays on too long or fails to activate, the Reznor 146464 provides the exact OEM response curve needed to protect the equipment and maintain occupant comfort.

• Precise Thermal Response: Fixed 135°F setpoint ensures the blower activates only when the heat exchanger is sufficiently primed.
• Compact Bracketless Design: Streamlines installation in cramped heating cabinets where standard mounting hardware is redundant.
• OEM Performance Standards: Manufactured to match original equipment specifications for timing and load handling.
• System Efficiency: Prevents premature fan operation, reducing energy waste and ensuring delivered air is always at the desired temperature.

Is the mounting bracket included with this part?
No, this version of the 146464 is provided without a mounting bracket (w/o brkt) for specific applications where the switch mounts directly to a pre-existing housing or faceplate.

What does the F135-30F rating signify?
This identifies a "Fan" logic. The switch closes (turns the fan on) when it senses a rise to 135°F and opens (turns the fan off) after a 30°F drop from that setpoint.

Will this work with other unit heater brands?
While the thermal specs may align, this part is specifically validated for Reznor gas-fired units. Always check your service manual to confirm the factory part number before installation.
