OEM vs. Generic

Genuine Goodman OEM caps are molded to the exact diameter and depth required for a snug, secure fit. Generic substitutes are often loose or oversized, leading to rattles, vibration noise, or caps that fall off during operation. For a maintenance-grade seal that stays put, OEM is the reliable choice.

Installation Difficulty

Easy (1/5) — No tools required. Simply press the cap into the appropriate port until seated. Always disconnect power before servicing your furnace.
