Trane SWT3968 Rollout Switch
The Trane SWT3968 Rollout Switch is a critical safety component engineered for gas-fired furnaces and HVAC systems. As a genuine OEM replacement part, this manual reset flame rollout switch is calibrated to open the electrical circuit when internal temperatures at the burner box exceed the fixed threshold of 190°F (L190F). Designed with an enclosed stainless steel disc and high-grade unplated brass terminals, this SPST (Single Pole Single Throw) control ensures precise thermal response and long-term reliability against nuisance tripping. Contractors typically utilize the SWT3968 to diagnose and prevent unsafe conditions resulting from cracked heat exchangers, blocked flue vents, or inducer motor failures. The switch features a standard 1/4 inch quick connect terminal for rapid field integration and a manual reset button to ensure a technician inspects the combustion area before system operation resumes. This robust limit control is rated for 24 VAC and specifically handles locked rotor currents up to 34.8A, making it compatible with various Trane and American Standard furnace models.
Key Benefits for Technicians- Precise Thermal Protection: Opens at exactly 190°F to mitigate fire hazards and prevent furnace cabinet overheating.
- OEM Standards: Genuine Trane SWT3968 (replaces SWT03968) ensures exact fitment and factory-spec safety ratings.
- Mechanical Manual Reset: Requires professional intervention after a trip, preventing repeated cycling until the underlying combustion issue is resolved.
- Durable Construction: Features tin-plated brass and nickel-plated steel components for superior conductivity and corrosion resistance in high-heat environments.
- What causes a Trane SWT3968 to trip? Common causes include a cracked heat exchanger leaking combustion gases, a restricted exhaust vent, or a failing inducer motor that cannot pull enough draft through the burners.
- Can this rollout switch be bypassed for testing? No. Safety switches must never be bypassed. If the switch trips, verify the heat exchanger integrity and flue draft using a manometer.
- Is the SWT3968 compatible with 24V control circuits? Yes, this HVAC rollout limit switch is designed for standard 24V AC residential control systems and features quick connect terminals for easy wiring.
