This OEM Goodman switch is calibrated to the exact -.50\" WC trip point your furnace board expects, ensuring reliable ignition sequencing. Generic substitutes often drift outside tolerance.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy to Moderate\u003c\/h3\u003e\u003cp\u003eTurn off power, transfer the vacuum tubing and wiring to the new switch, and mount it in the original position. Inspect the hose for cracks or condensate blockage while you're in there — a plugged port mimics a bad switch.
