Goodman 10123539 Manual Reset Limit Switch

The 10123539 is a genuine OEM Goodman manual reset limit switch (rollout/high-limit safety) built for the AMES920805CNAA gas furnace. This safety device opens the ignition/gas circuit when it detects abnormal heat or flame rollout in the burner compartment, protecting the heat exchanger and household from overheating. Because it is a manual reset device, it requires a deliberate button press to restore operation after a fault — a design that flags recurring problems rather than silently cycling.

Specifications

OEM Part Number: 10123539
Part Type: Manual Reset Limit / Rollout Switch
Reset: Manual (push-button)
Function: High-temperature / flame-rollout safety cutoff
Brand: Goodman / Amana
Compatible Model: AMES920805CNAA (gas furnace)

OEM vs. Generic

Safety limit switches must trip at the factory-calibrated temperature. Genuine OEM 10123539 units are matched to the AMES920805CNAA's heat exchanger and airflow design. Generic substitutes may carry an incorrect trip point, which can cause nuisance shutdowns or, worse, fail to protect the system. For a life-safety component, use OEM.

Installation Difficulty

Moderate (2/5) — Disconnect furnace power, remove the two mounting screws, transfer the wire leads to the new switch, and remount. Confirm secure spade connections. A meter check for continuity is recommended after install.

Fits the AMES920805CNAA and related Goodman/Amana models. Verify your original part number before ordering.
