Goodman 10123539 Manual Reset Limit Switch

The Goodman 10123539 is a genuine OEM manual reset high-limit / rollout safety switch for the AMEC960402BNAA gas furnace. This switch opens the ignition circuit and shuts the furnace down if it detects an over-temperature or flame-rollout condition, protecting the heat exchanger and your home. Because it is a manual reset device, it stays tripped until an operator presses the reset button — a deliberate safety feature that flags a fault for inspection. It is the factory-correct control for the Goodman/Amana AMEC-series burner box.

Specifications

OEM Part Number: 10123539
Type: Manual reset high-limit / rollout safety switch
Function: Normally closed; opens on over-temperature to shut off ignition
Reset: Manual push-button reset
Fits Model: AMEC960402BNAA (Goodman / Amana 96% AFUE gas furnace)
Equipment: Gas Furnace burner / heat exchanger safety circuit

OEM vs. Generic

The OEM 10123539 is calibrated to the exact trip temperature Goodman engineered for this heat exchanger. Generic limit switches with the wrong set point can nuisance-trip or, worse, fail to protect the furnace. This is a life-safety control — always use the genuine factory-matched part.

Installation Difficulty

Moderate (2/5). Two mounting screws and two spade terminals. Shut off power and gas first, photograph the wiring, and confirm the switch is fully seated against the mounting surface. If the switch keeps tripping after replacement, have a licensed HVAC technician diagnose the underlying cause before running the furnace.
