Texas Furnace(Consolidated Ind) 300919 Fan/Limit
The Texas Furnace (Consolidated Ind) 300919 Fan/Limit switch is a critical OEM replacement part designed for forced-air heating systems requiring a precise 8-inch insertion length. Built for high-stakes furnace safety and blower control, this combination controller regulates the fan motor cycles based on plenum temperature while providing a primary high-limit safety shut-off to prevent heat exchanger damage. As a professional-grade HVAC temperature control, it features a helical bimetal sensing element that ensures rapid response to thermal changes. The 300919 fan limit switch is a direct functional equivalent to the Resideo/Honeywell L4064B2236, offering adjustable fan-on and fan-off settings and a fixed high-limit stop. It supports multiple wiring configurations, including push-in receptacles and screw terminals, and includes a manual fan switch for continuous blower operation during the cooling season. For contractors, this universal furnace control is the go-to solution for servicing aging Consolidated Industries and Texas Furnace units where plenum temperature management is paramount.
Key Benefits:
- Integrated Safety: Combines fan cycling and high-limit protection in one 8" insertion probe assembly.
- Technical Compatibility: Direct OEM replacement for 300919 and cross-reference for L4064B2236.
- Field Flexibility: Features adjustable temperature pointers and a manual override for year-round air circulation.
- Robust Electrical Ratings: Designed for 120V or 240V AC circuits, handling heavy-duty blower motor loads.
- Reliable Sensing: The bimetal element provides consistent mechanical switching without the need for external power.
Common Questions:
What is the proper insertion depth for this control?
This specific model requires an 8-inch insertion. Always verify the depth of the previous controller to ensure the bimetal element is positioned in the center of the air stream without contacting the heat exchanger.
Can this be used on low-voltage (24V) circuits?
Yes, the 300919 fan/limit is suitable for millivolt, low-voltage, or line-voltage applications. For 24V limit circuits, the brass jumper must be removed to isolate the fan and limit sections.
How do I set the fan differential?
Use the front-facing dial to adjust the 'Fan On' and 'Fan Off' pointers. A 25-degree differential is standard to prevent blower short-cycling and ensure comfortable discharge air temperatures.
