Goodman 10123519 Manual Reset Limit Switch

The Goodman 10123519 is a genuine OEM manual-reset rollout/high-limit safety switch built for the GCH90453BXAB gas furnace. Like its companion switch, it protects the furnace and home by opening the control circuit if it senses excessive heat or flame rollout near the burner assembly or heat exchanger. It differs from part 10123517 by its factory trip temperature/mounting position — furnaces in the GCH90 series use more than one rollout switch at different points, so verify the number stamped on your original before ordering. A furnace that runs, then abruptly stops with a rollout fault, often points to one of these switches.

Part number: 10123519
Component: Manual reset rollout / high-limit safety switch
Function: De-energizes furnace on overheat or flame rollout
Reset type: Manual push-button
Fits: Goodman GCH90453BXAB and related GCH90 series

OEM vs. Generic

The OEM Goodman switch carries the precise temperature rating and bracket geometry specified for this position in the furnace. As a safety-critical limit, substituting a mismatched generic switch can cause nuisance trips or, worse, fail to protect against a genuine overheat. Match OEM specs exactly.

Installation Difficulty

Easy (DIY-friendly). Roughly 15 minutes with a nut driver — two screws and two push-on terminals. Cut power and gas before you begin, and investigate why the original tripped.
