The Goodman 10123519 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for Goodman GCH90703BXAB gas furnaces. It senses temperature at the heat exchanger/burner area and interrupts power to the gas valve during an overheat condition, guarding against heat exchanger damage and unsafe firing. The manual reset requires deliberate re-engagement, so a fault condition is always brought to a technician's attention rather than cycling unnoticed.

OEM vs. Generic

This switch is factory-calibrated to Goodman's specified trip point. Note that 10123519 carries a different temperature rating than the closely numbered 10123517 — verify your original part number before ordering. Generic substitutes with mismatched ratings risk nuisance lockouts or delayed shutoff, so the OEM part is strongly preferred for this safety device.

Install Difficulty

Moderate (2/5). Spade-terminal connections and screw mounting; confirm continuity with a meter. Cut power and gas before servicing. Professional installation recommended for safety controls.
