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

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

non-corrosive plastic for long-term reliability in wet environments

the 661057R is specifically sized (#57) for Liquid Propane (LP) applications

Nordyne 626422R Limit Switch High-Temp Performance: Designed to maintainThe 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
