York S1-025-29083-002 Rollout Switch

The York S1-025-29083-002 Rollout Switch serves as a fundamental safety device within the combustion chamber region of York and Source 1 gas furnaces. This SPST rollout switch is designed to sense excessive heat caused by flame rollout or improper venting, which can compromise the integrity of the cabinet and heat exchanger. The switch is calibrated to provide an open circuit at 300 degrees F, immediately breaking the electrical path to the gas valve to halt combustion. As an automatic reset rollout switch, it will revert to a closed state once the sensed temperature decreases to the 220 degrees F close set point. For contractors performing diagnostic repairs, utilizing this specific York furnace replacement part ensures the system remains within original equipment parameters. Its thermal response profile is specifically matched to the furnace's airflow dynamics, making it a reliable solution for maintaining HVAC safety limit switch standards in residential heating applications.

Key Benefits

• Direct OEM replacement for York S1-025-29083-002 ensures hardware and electrical compatibility.
• Automatic reset functionality eliminates the need for manual intervention after the component cools to 220°F.
• Precision thermal sensing at 300°F prevents hazardous conditions resulting from flame rollout.
• Simplified SPST design allows for straightforward integration into the existing furnace safety string.

Common Questions

What is the difference between a manual and automatic reset switch?
The York S1-025-29083-002 is an automatic reset switch, meaning it re-closes the circuit on its own once temperatures drop. Manual switches require a physical button press to restore furnace operation after a trip.

Why is my York furnace rollout switch tripping?
Tripping is usually indicative of a restricted flue, a clogged secondary heat exchanger, or improper manifold pressure causing flames to roll out of the burner opening during the ignition cycle.

Can I use a higher temperature switch as a replacement?
No. You must always use the manufacturer-specified temperature of 300°F to ensure the safety limit activates before the unit reaches hazardous temperatures or causes a fire risk.
