Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset high-limit switch for the AMEC800804CNAA gas furnace and compatible Goodman/Amana models. This safety control monitors combustion-area temperature and opens the circuit to shut down the burner if the furnace overheats or a flame rollout occurs, protecting the heat exchanger and your home. Because it is a manual-reset device, it must be pressed to restore operation after a trip — a design that flags recurring overheat conditions for service.

Specifications

OEM Part Number: 10123529
Category: Limit / Safety Switch
Type: Manual Reset High-Limit / Rollout Switch
Equipment: Gas Furnace (AMEC800804CNAA)
Brand: Goodman / Amana
Function: Overheat / flame-rollout safety shutoff

OEM vs. Generic

The OEM Goodman limit switch is calibrated to the exact trip temperature the furnace was engineered for, ensuring the safety circuit acts at the correct threshold. A mismatched generic switch can trip early (nuisance shutdowns) or too late (safety risk). For a safety-critical control, always use genuine OEM.

Installation Difficulty

Easy (2/5) — Two-wire terminal swap on the burner box; note lead orientation before removal. Cut power at the disconnect before servicing. If the switch keeps tripping, have the furnace inspected — repeated trips indicate an underlying fault.
