OEM vs. Generic

Our OEM option is the genuine Goodman-spec switch with the exact -0.10" WC calibration your control board expects — the safest choice for reliable ignition. The Generic option is a lower-cost aftermarket equivalent matched to the same trip point and terminal layout, ideal for budget repairs where an exact factory match is not required.

Installation Difficulty

Moderate. Requires disconnecting power, transferring the tubing and wiring to the new switch, and confirming the trip point matches. Most experienced DIYers complete it in 20–30 minutes; hire a technician if you are unsure about combustion safety.
