Goodman 10123519 Manual Reset Limit Switch

The Goodman 10123519 is a genuine OEM manual-reset high-limit / rollout safety switch for the GMH951155DXAD 96% AFUE furnace. This normally-closed thermal switch opens the ignition circuit and shuts down the burners if it senses flame rollout or excessive temperature at its mounting location — protecting the heat exchanger and household from unsafe over-temperature conditions. Once tripped, it must be manually reset (press the button) after the fault is diagnosed and cleared, which is exactly how a safety-critical limit should behave.

Specifications

OEM Part Number: 10123519
Part Type: Manual reset high-limit / rollout switch
Contact Configuration: Normally closed (opens on over-temp)
Reset: Manual push-button reset
Compatibility: Goodman GMH951155DXAD and related GMH95 series furnaces

OEM vs. Generic

The genuine OEM Goodman switch is calibrated to the exact cutout temperature this furnace requires. Generic limit switches may use a different trip point or terminal orientation, which can cause nuisance shutdowns or, worse, fail to protect at the correct temperature. For a safety device, always match the OEM specification.

Installation Difficulty

Easy (2/5) — Usually two mounting screws and two spade connectors. Shut off power and gas, note the wire positions, and never bypass a tripped limit — diagnose the root cause before resetting.
