The Goodman 10123539 Manual Reset Limit Switch is a genuine OEM flame-rollout safety control for the Amana/Goodman AMSS920803BNAA gas furnace. Mounted on the burner assembly, it senses abnormal heat from flame rollout and immediately opens the gas-valve circuit to shut the furnace down. Because it is a manual reset device, it stays tripped until an operator presses the reset button — a deliberate design that flags a real combustion problem rather than silently cycling.

Specifications

Part type: Manual reset rollout / flame limit switch
Reset: Manual push-button
Action: Normally closed, opens on overtemperature
Circuit: Interrupts gas valve / control circuit on trip
Fitment: Amana & Goodman furnaces (AMSS920803BNAA and related)
OEM part number: 10123539

OEM vs. Generic

The OEM 10123539 is calibrated to the exact trip temperature specified for this burner box and uses factory terminal spacing and bracket geometry for a bolt-in fit. Generic replacements may trip at the wrong temperature or require bracket modification — risky on a life-safety control. Always match the OEM spec on rollout switches.

Install Difficulty

Moderate (2/5). Shut off power and gas, photograph the wiring, unbolt the old switch, transfer the two spade connectors, and mount the new one. A repeated trip after replacement indicates an underlying rollout condition (blocked flue, cracked heat exchanger) that must be diagnosed by a technician.
