The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety cutout for the WFD18090S4BXCC furnace. It monitors heat-exchanger and plenum temperature and shuts off the gas valve and burners if the furnace overheats — protecting against restricted airflow, a failed blower, or a cracked heat exchanger. Unlike an auto-reset limit, this manual-reset version stays open until an operator presses the red button, so a repeat trip demands attention rather than silently cycling.

Specifications

Part type: Manual reset high-limit safety switch
OEM part number: 10123529
Brand: Goodman
Function: Overheat / rollout thermal cutout
Reset: Manual push-button
Fits model: WFD18090S4BXCC

OEM vs. Generic

The genuine Goodman OEM 10123529 is calibrated to the exact trip and reset temperatures engineered for this furnace. Generic limit switches with a different set point can nuisance-trip on normal high-fire cycles or, worse, fail to open soon enough during a real overheat event. For a safety-critical component, OEM calibration is not optional.

Installation Difficulty

Moderate (2/5). Shut off gas and electrical power, note wire orientation, remove the two mounting screws, transfer the spade connectors, and secure the new switch. Fifteen to twenty minutes for most DIYers. Important: a tripped limit switch is a symptom — always diagnose the underlying airflow or blower problem before replacing.
