Goodman 10123529 Manual Reset Limit Switch

The 10123529 is a genuine OEM manual reset high-limit / rollout switch for Goodman and Amana gas furnaces, including the AMEH800805DNAB. This safety device opens the control circuit and shuts down the burners if it detects excessive temperature or flame rollout, protecting the heat exchanger and your home from overheating. Because it is a manual-reset switch, it must be physically reset after a trip — and repeated tripping signals an underlying airflow or combustion problem to investigate.

Specifications

OEM Part Number: 10123529
Type: Manual reset high-limit / rollout switch
Reset: Manual (push-button)
Compatibility: Goodman & Amana furnaces incl. AMEH800805DNAB
Function: Overtemp/flame-rollout safety cutout

OEM vs. Generic

The OEM switch is calibrated to the exact trip temperature specified for your furnace. Generic limit switches with the wrong setpoint either nuisance-trip or fail to protect the unit. For a life-safety component, always match the OEM setpoint and mounting.

Install Difficulty

Easy to Moderate (2/5). Typically a two-screw, two-wire replacement. Do not bypass or jump out a tripped limit switch. Cut power at the disconnect, note wire positions, and address the root cause of any trips.
