The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for the AMEC800805CXAB gas furnace. This normally-closed high-limit/rollout switch trips and stays open when it detects an over-temperature or flame-rollout condition, cutting the gas circuit until an operator presses the manual reset button. The manual-reset design ensures a technician inspects the furnace before it can restart — a critical safeguard against repeated fault conditions.

OEM vs. Generic

The OEM switch is factory-calibrated to the exact trip temperature specified for this furnace, which is essential for a safety-critical control. Our Generic equivalent is a budget option matched to the same trip rating and terminal type; for safety devices, OEM is strongly recommended.

Installation

Difficulty: Easy. Cut power, remove the mounting screws, transfer the spade terminals, mount the new switch, and press reset. Roughly 15 minutes. Never bypass a manual-reset limit — a repeated trip indicates an underlying fault that needs diagnosis.
