preventing erratic flame signals and potential safety lockouts

Durable Brass Construction: High-grade material prevents orifice deformation and resists wear from high-velocity gas flow

Standard Goodman thermistors typically operate on a 10k ohm resistance scale at 77°F (25°C)

installing a fresh HVAC wireway is standard practice to ensure the system meets original factory safety configurations

Enhanced Pressure Containment: Specifically manufactured to maintain a leak-free seal at the body-to-bonnet junction under standard operating pressures

York S1-3500-3151/A Limit Switch preventing erratic flame signals andThe York S1 3500 3151 A Limit Switch is a critical safety component engineered for precise thermal regulation within HVAC furnace units and air handling systems. This specific high limit safety control operates with a fixed temperature range of 55 155F, acting as a primary safeguard against heat exchanger overheating. Featuring automatic reset functionality, the switch restores the electrical circuit once the internal temperature drops safely below
