The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit safety control for AMEH800805CNAA gas furnaces and compatible Goodman/Amana models. This switch monitors furnace temperature and trips to cut power to the gas valve if the unit overheats, protecting against heat-exchanger damage and fire. Because it is a manual-reset design, it requires the button to be pressed after a fault — a tripped or failed switch is a common cause of a furnace that shuts down or won't fire.

Specifications

  • OEM Part Number: 10123529
  • Part Type: Manual Reset Limit / Rollout Safety Switch
  • Compatible Equipment: AMEH800805CNAA and related Goodman/Amana furnaces

OEM vs. Generic

The OEM 10123529 is calibrated to the exact trip temperature specified for this furnace. Generic limit switches with the wrong set point can nuisance-trip or, worse, fail to trip during a genuine overheat. For a life-safety component, always use the OEM part.

Installation Difficulty

Easy to Moderate — two mounting screws and two spade terminals after disconnecting power. Confirm the replacement matches the original trip temperature. Estimated time: 15–20 minutes.

Common symptoms: unusual noises, intermittent operation, complete failure, or visible damage. Visit our diagnostic hub for symptom-based troubleshooting.
Is this limit switch compatible with Bryant or Payne too?
