Goodman 10123519 Manual Reset Limit Switch

The Goodman 10123519 is a factory OEM manual-reset limit switch built for the GCH91155DXAA gas furnace and related Goodman and Amana models. It functions as a temperature-activated safety control, opening the circuit to shut down burner operation whenever compartment or heat-exchanger temperatures exceed the furnace's rated limit. This protects the heat exchanger from cracking and prevents dangerous flame-rollout conditions. As a manual-reset switch, it will not auto-restart — it must be reset by hand once the overheat cause is corrected, ensuring problems are addressed rather than ignored.

Specifications

Type: Manual reset high-limit safety switch
OEM Part Number: 10123519
Brand: Goodman (Amana compatible)
Primary Fit: GCH91155DXAA gas furnace
Reset: Manual push-button
Function: Overheat and flame-rollout shutdown

OEM vs. Generic

Choosing the OEM 10123519 guarantees the correct trip point, terminal layout, and mounting footprint for your furnace. Aftermarket limit switches often use approximate temperature ratings that lead to premature trips or delayed protection. On a safety device, the genuine part is the right call every time.

Installation Difficulty

Easy (2/5). Plan for about 15–20 minutes. Disconnect power and gas, unscrew the switch from its mounting location, move over the wire terminals, and secure the replacement. Confirm and correct the airflow or blower issue that triggered the trip before restoring service. When in doubt, consult a qualified HVAC professional.
