Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual-reset high-limit switch designed as an exact-fit replacement for the AMH80603ANBC gas furnace and other compatible Goodman and Amana models. This critical safety control monitors heat-exchanger temperature and shuts off the gas valve if the furnace overheats — protecting against blocked airflow, failed blowers, or heat-exchanger problems. As a manual-reset device, it requires a deliberate button press to restore operation, ensuring a technician inspects the cause before the furnace restarts.

Specifications

  • OEM Part Number: 10123529
  • Part Type: Manual Reset High-Limit Switch
  • Function: Overheat / rollout safety shutoff
  • Reset: Manual push-button
  • Brand: Goodman / Amana
  • Fits Model: AMH80603ANBC (and select Goodman/Amana furnaces)

OEM vs. Generic

Safety limit switches are calibrated to a precise trip temperature. A genuine Goodman 10123529 trips at the exact factory-rated setpoint, so it protects the heat exchanger without nuisance shutdowns. Generic switches with mismatched setpoints can either fail to protect the unit or trip prematurely — never compromise on a safety control.

Installation

Difficulty: Easy to Moderate (2 of 5). Disconnect power, remove the two mounting screws, transfer the wire leads to the new switch, and remount in the same orientation. Confirm the sensor bulb or disc contacts the specified surface. After installation, restore power and verify normal cycling. Recommended for technicians and confident DIYers. Restore safe operation to your AMH80603ANBC with the OEM Goodman 10123529.
