Goodman 10123529 Manual Reset Limit Switch

The 10123529 manual reset limit switch is a genuine Goodman/Amana high-temperature safety control for the AMES801205DXAA 80% single-stage gas furnace. This switch opens the ignition circuit if it senses excessive heat or a flame-rollout condition, shutting down the burners to protect the heat exchanger and your home. Once tripped, it must be manually reset — a deliberate safety feature signaling that the cause should be investigated.

Specifications

OEM Part Number: 10123529
Component: Manual reset high-limit / rollout switch
Type: Normally closed, opens on temperature rise
Brand: Goodman / Amana
Equipment: 80% single-stage gas furnace

OEM vs. Generic

Safety limits are calibrated to a specific trip temperature. The genuine 10123529 is set to your furnace's exact rating, so it protects without nuisance trips. Substituting a generic switch with a different setpoint can either fail to protect or shut the furnace down prematurely. Always use the OEM-specified limit.

Installation Difficulty

Easy (2/5) — Two mounting screws and two spade terminals. Disconnect power, note wire positions, swap the switch, and reset. Typical time: 15–20 minutes. Diagnose and correct any airflow or rollout cause before restarting.

Disconnect gas and power before servicing. If the switch keeps tripping, call a licensed HVAC technician.
