This direct spark ignition assembly creates the initial arc and then remains in the flame path to provide the microamp signal back to the integrated furnace control board (IFC)

Featuring a highly stable 1K Ohm Platinum RTD (Resistive Temperature Detector) element

Should I replace the gasket every time I inspect the float mechanism

High-Temp Performance: Designed to maintain a secure seal under fluctuating steam pressures and high-temperature conditions

Nordyne 626422R Limit Switch This direct spark ignition assemblyThe Nordyne 626422R Limit Switch is a critical safety component designed for furnace rollout protection in gas fired and oil fired HVAC systems. This thermal limit switch is engineered to open the circuit at a 155F cut out temperature, immediately interrupting the gas valve circuit if flame rollout or excessive heat is detected near the burner box. As a manual reset rollout switch, it requires a technician to physically inspect the heat exchanger and
