The Goodman 10123529 is a genuine OEM manual-reset limit switch engineered for the WFM18045S3AXCB gas furnace and cross-compatible Goodman/Amana models. Unlike an automatic-reset control, this switch latches open when it trips and must be manually reset with the push button — a deliberate safety design that forces a technician or homeowner to acknowledge and investigate an overheat or flame-rollout event before the furnace can fire again.

Specifications

Type: Manual-reset high-limit / rollout switch
Reset: Push-button (latching)
Terminals: Quick-connect spade
Fit: Goodman WFM18045S3AXCB and cross-referenced models
Mount: Bracket / flange with retaining screws

OEM vs. Generic

Genuine Goodman calibration ensures the switch opens at the precise factory-specified temperature. Aftermarket substitutes may use a mismatched trip point that either nuisance-trips on normal cycles or dangerously delays a shutdown. Because this is a life-safety limit, the OEM part is the recommended choice and keeps your equipment within manufacturer and warranty specs.

Installation Difficulty

Easy (1/5). Plan for 10–15 minutes: disconnect power, remove the mounting screws, transfer the two spade terminals, and remount. Press the reset button after installation. If the switch continues to trip after reset, do not bypass it — a repeated manual-reset trip signals a real overheating or rollout problem that a licensed HVAC technician should diagnose.

Turn off all electrical power and gas before servicing.
