this sensor converts physical pressure into a linear 0

Technicians should perform a continuity test across the terminals while manually displacing the internal paddle or simulating a no-flow condition to ensure the microswitch is opening and closing the circuit correctly

the board ensures the heat exchanger reaches a stable discharge temperature—typically requiring a 45-second ignition delay—to prevent cold air drafts during the initial heating cycle

This design facilitates greater discharge flow and reduces the risk of backpressure

Can I return this part if it does not solve my ignition issue
