Goodman 10123533 Manual Reset Limit Switch

The Goodman 10123533 is a genuine OEM manual-reset high-limit safety switch built for GMS950904CXA 95% AFUE gas furnaces and compatible high-efficiency models. This normally-closed thermal switch monitors temperature at the heat exchanger or burner area and opens the circuit if it detects an unsafe overheat condition — shutting down the furnace to prevent damage or fire. Its manual reset button requires a technician to physically restore the circuit, ensuring the root cause is addressed before the furnace restarts.

OEM vs. Generic

Because this is a safety control, an incorrectly calibrated generic switch may trip too early (nuisance shutdowns) or too late (unsafe overheating). The OEM 10123533 is set to Goodman's exact trip point, guaranteeing the furnace shuts down at the right temperature every time.

Install Difficulty: Moderate

Plan 15–25 minutes. Turn off gas and electrical power, remove the burner or blower access panel, note the wiring, and unscrew the old switch. Mount the new switch in the same location, reconnect the terminals, and press the reset button. If the switch trips again, diagnose the underlying overheat cause. Confirm the part number matches your unit before installing.

Safety-critical replacement part. Professional installation strongly recommended.
